Most Helpful Review
"Ordered this with a solar charge cable from their promo offering,when i received the order they only send me the charge cable.Because of this i wrote a negative review for the seller and was about to open a claim.Few days later i received the actual power station.I removed my negative seller review and maybe in the future the seller could inform that the cable ships separately from the actual order to avoid confusion !The power station works great, tested it only with my laptop and was able to get almost a full day out of it.Some weird buzzing occurs when charging the station, electrical noise...Charges really fast but is noisy when the fan kicks in.The power station is relatively light and easy to carry, interface has all the useful info that is needed and it can also be linked to your phone with their app.The only thing i dislike is that you need internet in order to link it with your phone and to create an account. The power station connects directly to your wifi network which makes no sense to me."

This is a wonderful little unit to plug a lamp or fan into and charge phones during hurricanes and other power outages. I consider it a great value for the money.jose guillermo jimenez
