Please differentiate between Watts and Watt-Hours. In this context, Watts can be considered a rate, and Watt-Hours can be considered a capacity. Lots of people seem to be conflating these two measurements. They are related, but different.
Yes, that is true - but this device is both 300W (max AC 120V output) and ~300 Wh (actually rated at 293.76 Wh) battery storage capacity. There's no confusion here.
@@FuncleChuck Almost all such devices have a different number between capacity (wh) and power provided (w). In fact, the TSA has confiscated a 100wh battery pack that said it provided 200w output. This confusion can have real consequences. So, it is important to make the distinction.
My travel CPAP machine uses an average of about 20 watts, as I use it. (no heater or humidifier) If that battery truly has 300 watt-hours capacity and I can connect to 12 volts DC directly, then it should last about 300/20 = 15 hours. (Your mileage WILL vary.)
For $130 that's a decent little package, charges from 12VDC or 120VAC or Solar (up to 18VDC)... 300W is pretty weak but it's way more than enough for anything that you could reasonably want to run with only 293 Wh of capacity (1 hour at peak) - plus those cheap 100W solar panels you'd take camping basically only make ~300Wh on an average day anyway. They show that they make a 600 and 1000 version of this too, but the Amazon links do not work for those... That's concerning.
Excellent review y’all! Thank you for the insight and feedback on this product :) I’ve been wanting a battery solution and seeing what you guys test, really has helped!

Remember not to let it overheat. Ie storing in the car on a sunny day.
Is it ok to hook up to e bike? Charge as you go
