Battery came fully charged but I put it on the charge over night anyway. I connected it up to my new fish finder and ran it 24/7 for the next 7 days. Before connecting the fish finder I checked the voltage and it read 13.35 volts, 7 days later when I unplugged it I checked it again and it read 11.31 volts. I would say this was an excellent buy!!!

An excellent 12v to bring along camping. I do not have a depth finder, but use some 12v devices that have alligator clips. This is a very nice and compact unit that has outlasted our needs many times.
I really like that it included a charger, makes charging easy. I don't know what else to tell ya'll. Looks well made and it works great for all kinds of 12v applications.

I put this in a cheap tool box and added a few 12V car cigarette outlets for power, solar panel charge controller, speakers from an old set of self powered computer speakers and on off switch. made a portable power unit that can be used with a 12V to AC adapter to power just about anything. Used it when the power went out in San Diego. Also use it when golfing, fishing and car trips. It can power cells phones, camcorders, cameras etc. You can also plug a mp3 player into the speakers for tunes.

I like having a power supply in case the solar panels don't charge the battery all the way. Very cool!
