  • Great size and options for use when the need arises
Size: S400
Stores on a closet shelf so not too bulky or heavy. Has all the options I think I may need for hurricane outages and can travel easily too

  • Better than I expected. Great value!
Size: S400
Got this because my previously (self-made) lead-acid power box died. You can't beat this thing. -Lightweight -Multiple ways to charge (Wall AC, Solar, 12V) -Pass-Thru charging (The inverter draws 5W at idle. When I was running a 5W device, my output was 10W. Plugged in the 60W charger it comes with and I was charging at 50W. It took 10W of the input to power the load and sent the rest to the battery) -Great Display (Tells you what's on , Net power loss/gain, time to charge/discharge ) I have this thing running a mini-fridge. It's losing 5% per hour. The fridge draws 60W for 15 mins every hour. I'm recharging off a 100W panel. It comes with all the cables you need (wall brick, 12V to 5521, MC4 to 5521) At the price, this thing is a steal! ... show more

  • Excellent, long lasting power station
Size: S400
A few weeks ago our power went out because of a storm for nearly a week. I was able to keep the power station charged with solar power. And the station even ran my satellite internet so that I could keep touch with the world. I was pleasantly surprised how long it lasted.

  • Wont Charge on solar
Size: S400
Hi, guys This unit has never charged off of 220w panels @up to 15.5w. Charges good from car and wall. if you want to charge it from solar buy something else. The customer service help line will tell you its your panels too much voltage , i thought that is what charge controllers do.

  • Great 👍 dispay. Show a lot of useful charge and discharge data so you can plan wisely your usage.
Size: S400
Awesome, took it camping and charged up all my devices and even used some 12v lights at the camp site and still had enough juice in the morning then I charged it up with a 100watt solar panel so we could have it ready to use at night. I like that you can see the % of battery life as well as the time remaining. ... show more

  • It's Great!!!
Size: S400
I currently have two different ExpertPower Generators and they're both wonderful. My satisfaction with the first generator's performance is what lead me to purchase a second generator from the same company.
