Wall charged the unit to full strength and then tested AC output with two 60 watt light bulbs (showed output of appx 105 watts). Battery lasted 2 1/2 hours, which is about right. (unit automatically shuts off when down to 10% level).


Recharged the unit using a Kingsolar 120W solar panel. Took 6 1/2 hours, but day was partly cloudy and February sun in Pennsylvania not terribly strong… max panel output was only about 80 watts.


Purchased in Feb 2016. Battery was delivered in 3 days. Excellent packaging.

Included In The Package

Unit arrived with four cables: AC wall charger (80 Watt output); solar charger cable (4 1/2′ long) with MC4 connectors to Anderson connectors; DC car charging cable (2 1/2′ long); and jump starter with alligator clip cable (1′ long).

Bottom Line

All in all, very happy with battery and accessories. Performing as advertised. Very light and easy to move about. No noise. Didn’t get hot. Screen easy to read. Fits nicely in 6 gal faraday container. Li-ion the way to go.


Wish they had a 600W version.
