5 Stars
Surprisingly excellent value for on-the-go and emergencies. A bit bulky for its size
Those who have been following my reviews for some time know that I'm an aficionado for battery power stations and have reviewed many more than I can remember -- from manufacturers like Goal Zero, Jackery, Rockpals, Paxcess, Suakoi, BigBlue, Golabs, Aimtom, and more. This Aimtom is my first experience with the brand. It appears to be a Chinese/Canadian company.If you live in areas hit by disasters (hurricanes, tornadoes, fires, or just plain power outages), I cannot stress how important it is to be prepared for emergencies. There has been an increase in people taking emergency preparation more seriously.IN A NUTSHELLLike the majority of battery power stations, this Aimtom Rebel440 does not produce much noise like a gas generator. As such, it can be brought to camp sites that have noise restrictions and also can be used indoor in an enclosed area. No worries about carbon monoxide poisoning. We use the battery to charge phones, fans (the hot summer heat can be unbearable), a mini humidifier, and multiple light bulbs for the kids to run around at night. The built-in light comes in handy too for cooking or inside the tent. I found the model name curious: "Rebel". What was Aimtom rebelling against? As it turned out, there were a few features and design choices that differed from most of the competition.The "440" in the model number indicates 440W of continuous AC output -- enough to power a car freezer (like Dometic, Alpicool, Foho, Domende, etc) for about 3/4 day, depending on ambient (surrounding) temperatures. It can then be charged from the AC wall, car DC cigarette port, solar panels, or USB-C PD. Keep in mind that the AC output outlets use up 7W more power than the USB/DC/Cigarette ports, and so always try to use those instead of the AC ones. Try it out: turn on JUST the AC outlets without anything connected. You should be able to measure about 7W of power wasted due to the DC-to-AC inverter being turned on.I will explain the difference between Watts (W) and Watt-hours (Wh) later.Of noticeable difference rarely seen with batteries of this size is the inclusion of 3 AC outlets -- many only come with one or two. I also found the outlets to be generously spaced apart and something I would normally see on larger power stations. The Aimtom allows for USB-C PD (Power Delivery) charging and discharging (meaning, it can be used to both charge the Rebel440 or an external device, like a laptop) at an impressive 100W. What should be pointed out is that you can combine the 100W USB-C PD port with either the 96W AC brickwall or up to 100W of solar input for a combined charging total of 200W. Not many batteries at this size include that feature and it is good to see more manufacturers add that. What this means for you is that the battery can be charged to 80% (from empty) in a little over 1.5 hours. It will take another 30-60 mins to go 100% as charging speed automatically gets throttled by the BMS (Battery Management System) as a safety mechanism.How long can you use this 403Wh battery for? It can power up to 403W in an hour. So, if your laptop uses 50W of power per hour, that's 50W x 8 hours = 400Wh. The laptop could last for about 6-8 hours, depending on how you use it.Keep the battery charged between 50-80% when not in use. Don't let it fall below 20%, and don't let it be at 0% for too long, or the Lithium-ion battery cells can become so damaged, it cannot be recharged without deep cycling it with specialized gear.The hard, plastic material used to help shed weight (and cost) could be prone to cracking from hard falls or bumps, potentially exposing the Lithium-Ion batteries to puncturing. The carry handle can be folded, making it not ideal for packing things on top.Functionally, this is a good, portable power station with a multitude of AC and DC outputs.You can use the AC output while its battery is charging. A cigarette port and MC4 solar charging cable are included. The Aimtom includes a MPPT controller for more efficient, faster solar charging.Although the battery is very light (10 lbs), it physically is a bit bulky (9" x 7" x 7") when compared to the Goal Zero Yeti 500x and Rockpals 500W (both of which pack an additional 100Wh of capacity over the Aimtom.) I do like that the carry handle can be folded away flat, making it easier to pack things on top in a car trunk full of other gear. The color scheme looks similar to Jackery's.The built-in light can be used to illuminate the camp site, and when long-pressed, activates the flashing, SOS Help signal. I'm in love with the crisp, bright LED display -- many manufacturers are starting to implement that type of technology into their products.CONTINUOUS VS PEAK OUTPUTIt is important to understand the difference between Watts and Watt-Hours. How much power is used or produced is measured in Watts, and how much energy a battery can store is calculated in Watt-Hours. See the "Calculations" section below for more details.- How much energy a battery can store is measured in Wh (Watt-hours), and how much power is used or produced in W (Watts).- Most devices power on at a higher (Peak) wattage than when they are already on (Continuous). Therefore, if its peak exceeds the power station's max, it may not be able to start- AC Inverter: Converts battery (DC) power into ACThe AC Inverter provides a continuous output of 440W with a peak/surge of 800W- AC Inverter: Component responsible for converting battery (DC) power into AC for use by electronics- Continuous Output: As long as a device (or combination of multiple ones) does not exceed 440W, it can be used-- Example: A TV that uses 100W can be used because it is less than 440W. You can add more devices as long as they do not exceed 440W combined-- Example: A miter saw I have uses 1,800W, and because it exceeds 440W, it cannot be used- Peak/Surge: Almost every device temporarily draws more power when it is turned on. The highest amount it pulls during that time is the Peak/Surge. This power station can accept up to 800W-- Example: A TV that uses 200W (continuous) may temporarily suck up 400W (peak) when powered on. Because 400W is less than 800W (peak), this battery will allow the TV to turn on at that level for a few seconds (any longer, and it might cut power as a safety precaution). After a few seconds, the TV then only uses 200W (less than the continuous 440W limit) until the battery is drained-- Example: An unusual device that uses 250W (continuous) and surges to 1,500W when powered on would instantly be shut off by the battery. Why? Even though the device uses just 250W while already on, it jumps to 1,500W when powered on, exceeding the 800W surge limit of the power stationCALCULATIONSThe below calculations are rough estimates as conditions, quality, and product age can vary.CHARGING TIMES- Wall charger: 5-6 hours-- AC adapter was observed to provide 96W when charging level was at 67%-- AC adapter will gradually charge slower as battery reaches full capacity (for safety reasons)- 100W solar panel: depending on weather conditions, it should take about 5-8 hours. I did not test this as the winter sun is not very strong-- WARNING: do NOT connect panels sequentially or you may output too much voltage and fry the power station! Connect them in PARALLEL with a Y-Branch cable- Aimtom Rebel440 can combine its 6mm (100W) and USB-C PD (100W) ports for a total, maximum input of 200W-- Can fully charge battery in as fast as 2.7 hoursHOW MANY WATTS DOES A DEVICE US?- Calc: Watts used by device = Voltage x Amperage- If a vacuum is 120V and 9.5A, it uses 1,140WIf a device draws more than 500W for an extended period of time, the power station will shut off as a safety precaution. This can also shorten the battery's lifetimeHOW LONG CAN A DEVICE BE USED FOR?- Calc: Hours available for device = Battery capacity (Wh) x 0.85 / Watts used by device-- Generally, about 10-15% of power is lost during power conversion- If a device uses 60W, it could last up to 5.7 hours (403 Wh x 0.85 / 60W)- Amazon TV I have uses about 100W-- If battery is full at 403 Wh, TV could run about 3.6 hours (403 Wh x 0.9 / 100)HOW LONG DOES IT TAKE TO CHARGE A DEVICE?- Calc: Hours to charge device = Device's battery capacity (Wh) / Input Wattage- If a laptop accepts 60W of input and its battery capacity is 200 Wh, it could take 3.3 hrs to charge (200 Wh / 60W)HOW LONG DOES IT TAKE TO CHARGE THE AIMTOM REEL440 WITH SOLAR?- Calc: Hours to charge battery = Battery capacity (Wh) / (Panel Wattage x [0.5 or 0.75])-- In a perfect lab environment, solar panels charge at the indicated wattage (ie. 150W)-- Expect to only receive 50-75% on a good, sunny day (ie. 75W - 113W), depending on environmental conditions, panel's age, and component quality-- Tip: Even if it is overcast, the panels will STILL collect solar energy. Keep charging!- If a solar panel is rated for 100W, it could take as fast as 5.37 hours [403 Wh / (100W x 0.75)] to charge-- If combined with the 100W USB-C PD port, it could be as quickly as 2.7 hours [403 Wh / (200W x 0.75)]HOW DOES ITS CAPACITY COMPARE TO POWER BANKS?- Calc: Powerbank-equivalent capacity (mAh) = Battery capacity (Wh) / Voltage x 1000-- 1 Ah = 1000 mAh- A battery capacity of 403Wh at 3.6V is roughly a 111,944 mAh powerbank (403 Wh / 3.6V x 1000) or a 37,314 mAh at 10.8VTIPS- Always test your devices with the power station before you depend on it on the go- Lithium-ion batteries are volatile-- To minimize fire damage to your belongings or loved ones, store the power station in the garage and not inside the house. Best storage is a dry, cool place, however-- You cannot bring a battery of this capacity on a plane- With the right BMS, quality batteries, and other factors, the power station can be stored in the car while camping during a hot, California summer-- Keep the battery out of direct sunlight. I usually store it on the floor of the car and crack open the windows a tiny bit-- Do not USE in the car if temperatures fall below or exceed the battery's rated, operating temperature (32-104F or 0-40C)Keep your car cigarette lighter with the power station -- you could plug it into its 12V DC socket for starting a camp fire- If using a car charger, make SURE you only charge this station while the car is RUNNING. Otherwise, you'll deplete your car's battery and leave you stranded- If charging with a solar panel, be sure to keep the station out of direct sunlight as it could overheat-- A solar panel is NOT required to use the battery-- Aimtom Rebel440 uses the MPPT solar charge controller--- Smarter, more efficient/expensive than PWM--- Suitable for larger systems- Can be used and charged at the same time. Manufacturers' recommendations for their own products:-- Yes, that's fine: Paxcess, Goal Zero, Jackery, Rockpals, nrgGo-- No/Not advisable: Suaoki- NEVER charge the power station itself in below freezing temperatures, or you will damage the Li-ion battery AND potentially limit its overall capacity-- You CAN use it to power OTHER devices because the generated heat will warm its battery enough to be within operating temps-- At below freezing temps, keep it in an insulated cooler and connected to a power source (ie. solar panels). The heat generated by the battery will keep it running as best as it can- Turn off any output ports (AC/DC) that are not being used in order to conserve power- Do not use any power station in a tightly enclosed area as it can overheat- To prolong the battery lifetime while in storage, keep the battery fully charged every 3-6 months-- Or, keep it plugged in when not in use and discharge it to 50% every 3-4 months-- NOT using the battery for a very long time can actually hurt its lifetime-- There is no "memory effect" in this station's battery. It is better to NOT let it completely drainFINAL THOUGHTSThe Aimtom 500 is a decent battery. In fact, it provides pretty good value when you consider that it includes a feature set commonly found in larger products.The 440W of energy (and peak of 800W) provides enough power for a small amount of electronics and small appliances, and is the perfect size for a quick trip or to charge something for a few hours (like my car freezer).The hard, plastic material commonly used by power stations to help shed weight and cost could be prone to cracking from hard falls or bumps, and as such, this product should be handled with care - a puncture of the Lithium-Ion batteries could cause severe harm. It has a significant price advantage over the industry leaders.I will be keeping a closer eye on Aimtom's batteries and see where they are going.

As such, it can be brought to camp sites that have noise restrictions and also can be used indoor in an enclosed area. No worries about carbon monoxide poisoning. We use the battery to charge phones, fans (the hot summer heat can be unbearable), a mini humidifier, and multiple light bulbs for the kids to run around at night. The built-in light comes in handy too for cooking or inside the tent. I found the model name curious: "Rebel". What was Aimtom rebelling against? As it turned out, there were a few features and design choices that differed from most of the competition.

The "440" in the model number indicates 440W of continuous AC output -- enough to power a car freezer (like Dometic, Alpicool, Foho, Domende, etc) for about 3/4 day, depending on ambient (surrounding) temperatures. It can then be charged from the AC wall, car DC cigarette port, solar panels, or USB-C PD. Keep in mind that the AC output outlets use up 7W more power than the USB/DC/Cigarette ports, and so always try to use those instead of the AC ones. Try it out: turn on JUST the AC outlets without anything connected. You should be able to measure about 7W of power wasted due to the DC-to-AC inverter being turned on.

I will explain the difference between Watts (W) and Watt-hours (Wh) later.

Of noticeable difference rarely seen with batteries of this size is the inclusion of 3 AC outlets -- many only come with one or two. I also found the outlets to be generously spaced apart and something I would normally see on larger power stations. The Aimtom allows for USB-C PD (Power Delivery) charging and discharging (meaning, it can be used to both charge the Rebel440 or an external device, like a laptop) at an impressive 100W. What should be pointed out is that you can combine the 100W USB-C PD port with either the 96W AC brickwall or up to 100W of solar input for a combined charging total of 200W. Not many batteries at this size include that feature and it is good to see more manufacturers add that. What this means for you is that the battery can be charged to 80% (from empty) in a little over 1.5 hours. It will take another 30-60 mins to go 100% as charging speed automatically gets throttled by the BMS (Battery Management System) as a safety mechanism.

How long can you use this 403Wh battery for? It can power up to 403W in an hour. So, if your laptop uses 50W of power per hour, that's 50W x 8 hours = 400Wh. The laptop could last for about 6-8 hours, depending on how you use it.

Keep the battery charged between 50-80% when not in use. Don't let it fall below 20%, and don't let it be at 0% for too long, or the Lithium-ion battery cells can become so damaged, it cannot be recharged without deep cycling it with specialized gear.

The hard, plastic material used to help shed weight (and cost) could be prone to cracking from hard falls or bumps, potentially exposing the Lithium-Ion batteries to puncturing. The carry handle can be folded, making it not ideal for packing things on top.

Functionally, this is a good, portable power station with a multitude of AC and DC outputs.

You can use the AC output while its battery is charging. A cigarette port and MC4 solar charging cable are included. The Aimtom includes a MPPT controller for more efficient, faster solar charging.

Although the battery is very light (10 lbs), it physically is a bit bulky (9" x 7" x 7") when compared to the Goal Zero Yeti 500x and Rockpals 500W (both of which pack an additional 100Wh of capacity over the Aimtom.) I do like that the carry handle can be folded away flat, making it easier to pack things on top in a car trunk full of other gear. The color scheme looks similar to Jackery's.

The built-in light can be used to illuminate the camp site, and when long-pressed, activates the flashing, SOS Help signal. I'm in love with the crisp, bright LED display -- many manufacturers are starting to implement that type of technology into their products.

CONTINUOUS VS PEAK OUTPUT
It is important to understand the difference between Watts and Watt-Hours. How much power is used or produced is measured in Watts, and how much energy a battery can store is calculated in Watt-Hours. See the "Calculations" section below for more details.

- How much energy a battery can store is measured in Wh (Watt-hours), and how much power is used or produced in W (Watts).
- Most devices power on at a higher (Peak) wattage than when they are already on (Continuous). Therefore, if its peak exceeds the power station's max, it may not be able to start
- AC Inverter: Converts battery (DC) power into AC

The AC Inverter provides a continuous output of 440W with a peak/surge of 800W
- AC Inverter: Component responsible for converting battery (DC) power into AC for use by electronics
- Continuous Output: As long as a device (or combination of multiple ones) does not exceed 440W, it can be used
-- Example: A TV that uses 100W can be used because it is less than 440W. You can add more devices as long as they do not exceed 440W combined
-- Example: A miter saw I have uses 1,800W, and because it exceeds 440W, it cannot be used
- Peak/Surge: Almost every device temporarily draws more power when it is turned on. The highest amount it pulls during that time is the Peak/Surge. This power station can accept up to 800W
-- Example: A TV that uses 200W (continuous) may temporarily suck up 400W (peak) when powered on. Because 400W is less than 800W (peak), this battery will allow the TV to turn on at that level for a few seconds (any longer, and it might cut power as a safety precaution). After a few seconds, the TV then only uses 200W (less than the continuous 440W limit) until the battery is drained
-- Example: An unusual device that uses 250W (continuous) and surges to 1,500W when powered on would instantly be shut off by the battery. Why? Even though the device uses just 250W while already on, it jumps to 1,500W when powered on, exceeding the 800W surge limit of the power station

CALCULATIONS
The below calculations are rough estimates as conditions, quality, and product age can vary.

CHARGING TIMES
- Wall charger: 5-6 hours
-- AC adapter was observed to provide 96W when charging level was at 67%
-- AC adapter will gradually charge slower as battery reaches full capacity (for safety reasons)
- 100W solar panel: depending on weather conditions, it should take about 5-8 hours. I did not test this as the winter sun is not very strong
-- WARNING: do NOT connect panels sequentially or you may output too much voltage and fry the power station! Connect them in PARALLEL with a Y-Branch cable
- Aimtom Rebel440 can combine its 6mm (100W) and USB-C PD (100W) ports for a total, maximum input of 200W
-- Can fully charge battery in as fast as 2.7 hours

HOW MANY WATTS DOES A DEVICE US?
- Calc: Watts used by device = Voltage x Amperage
- If a vacuum is 120V and 9.5A, it uses 1,140W

If a device draws more than 500W for an extended period of time, the power station will shut off as a safety precaution. This can also shorten the battery's lifetime

HOW LONG CAN A DEVICE BE USED FOR?
- Calc: Hours available for device = Battery capacity (Wh) x 0.85 / Watts used by device
-- Generally, about 10-15% of power is lost during power conversion
- If a device uses 60W, it could last up to 5.7 hours (403 Wh x 0.85 / 60W)
- Amazon TV I have uses about 100W
-- If battery is full at 403 Wh, TV could run about 3.6 hours (403 Wh x 0.9 / 100)

HOW LONG DOES IT TAKE TO CHARGE A DEVICE?
- Calc: Hours to charge device = Device's battery capacity (Wh) / Input Wattage
- If a laptop accepts 60W of input and its battery capacity is 200 Wh, it could take 3.3 hrs to charge (200 Wh / 60W)

HOW LONG DOES IT TAKE TO CHARGE THE AIMTOM REEL440 WITH SOLAR?
- Calc: Hours to charge battery = Battery capacity (Wh) / (Panel Wattage x [0.5 or 0.75])
-- In a perfect lab environment, solar panels charge at the indicated wattage (ie. 150W)
-- Expect to only receive 50-75% on a good, sunny day (ie. 75W - 113W), depending on environmental conditions, panel's age, and component quality
-- Tip: Even if it is overcast, the panels will STILL collect solar energy. Keep charging!
- If a solar panel is rated for 100W, it could take as fast as 5.37 hours [403 Wh / (100W x 0.75)] to charge
-- If combined with the 100W USB-C PD port, it could be as quickly as 2.7 hours [403 Wh / (200W x 0.75)]

HOW DOES ITS CAPACITY COMPARE TO POWER BANKS?
- Calc: Powerbank-equivalent capacity (mAh) = Battery capacity (Wh) / Voltage x 1000
-- 1 Ah = 1000 mAh
- A battery capacity of 403Wh at 3.6V is roughly a 111,944 mAh powerbank (403 Wh / 3.6V x 1000) or a 37,314 mAh at 10.8V

TIPS
- Always test your devices with the power station before you depend on it on the go
- Lithium-ion batteries are volatile
-- To minimize fire damage to your belongings or loved ones, store the power station in the garage and not inside the house. Best storage is a dry, cool place, however
-- You cannot bring a battery of this capacity on a plane
- With the right BMS, quality batteries, and other factors, the power station can be stored in the car while camping during a hot, California summer
-- Keep the battery out of direct sunlight. I usually store it on the floor of the car and crack open the windows a tiny bit
-- Do not USE in the car if temperatures fall below or exceed the battery's rated, operating temperature (32-104F or 0-40C)

Keep your car cigarette lighter with the power station -- you could plug it into its 12V DC socket for starting a camp fire

- If using a car charger, make SURE you only charge this station while the car is RUNNING. Otherwise, you'll deplete your car's battery and leave you stranded
- If charging with a solar panel, be sure to keep the station out of direct sunlight as it could overheat
-- A solar panel is NOT required to use the battery
-- Aimtom Rebel440 uses the MPPT solar charge controller
--- Smarter, more efficient/expensive than PWM
--- Suitable for larger systems
- Can be used and charged at the same time. Manufacturers' recommendations for their own products:
-- Yes, that's fine: Paxcess, Goal Zero, Jackery, Rockpals, nrgGo
-- No/Not advisable: Suaoki
- NEVER charge the power station itself in below freezing temperatures, or you will damage the Li-ion battery AND potentially limit its overall capacity
-- You CAN use it to power OTHER devices because the generated heat will warm its battery enough to be within operating temps
-- At below freezing temps, keep it in an insulated cooler and connected to a power source (ie. solar panels). The heat generated by the battery will keep it running as best as it can
- Turn off any output ports (AC/DC) that are not being used in order to conserve power
- Do not use any power station in a tightly enclosed area as it can overheat
- To prolong the battery lifetime while in storage, keep the battery fully charged every 3-6 months
-- Or, keep it plugged in when not in use and discharge it to 50% every 3-4 months
-- NOT using the battery for a very long time can actually hurt its lifetime
-- There is no "memory effect" in this station's battery. It is better to NOT let it completely drain

FINAL THOUGHTS
The Aimtom 500 is a decent battery. In fact, it provides pretty good value when you consider that it includes a feature set commonly found in larger products.

The 440W of energy (and peak of 800W) provides enough power for a small amount of electronics and small appliances, and is the perfect size for a quick trip or to charge something for a few hours (like my car freezer).

The hard, plastic material commonly used by power stations to help shed weight and cost could be prone to cracking from hard falls or bumps, and as such, this product should be handled with care - a puncture of the Lithium-Ion batteries could cause severe harm. It has a significant price advantage over the industry leaders.

I will be keeping a closer eye on Aimtom's batteries and see where they are going.

5.0 out of 5 stars Solid performance
Reviewed in Canada on November 30, 2023
This is a good little power station. It outputs a steady 109.8 volts. Full battery discharge test per the pictures involved a mini heater pulling around 225 watts for 1hr35m and a total of 0.357kwh used, or 88.5% of the 403 watt hour rated capacity of the battery. That's not too shabby a result. Under 50% load the fan only kicks on periodically and isn't loud. Charges around 88w with the included charger. Well made and performs according to specs. No complaints.
