Wouldn't be worth the price IF it held a charge.

The battery can't hold a charge for a week. I've tried 3 different charging methods to see if I could get better results. I tried charging it for over a day using the solar panel, charging it via the power adapter, and leaving it on the power adapter for a week straight. Every time the battery claimed to be full and when I checked it a week later it was completely dead. TOTAL GARBAGE!!! Do yourself a huge favor by not blowing a couple hundred dollars on this battery which doesn't perform, buy a Symtek TF200 for $25 same 50 watts,much smaller size, actually holds a charge, and is a fraction of the cost.

Shortly after writing my initial review I had plugged in my goal 0 battery to fully charge. My plan was to check it every 24 hours to see just how long it was holding a charge. After about 4 hours of having it plugged in I went to check on if it was fully charged, and to my horror it was blinking all sorts of lights and had a huge bulge in the middle of the battery, NOT GOOD! I immediately contacted goal 0 via their online chat. They didn't ask me a single question other than what my address was so they could send me out a brand new battery I was pretty happy about the exchange being hassle free! The very next day I had a package from goal 0 with my brand new battery. I've only had it for a few day's now and I'm trying to run it through it's paces to stress test it. It seems to be holding a charge longer than my original ever did. I still plan on doing my check every 24 hours to see how long it holds a charge for on this new one. Also this battery has some slight differences between the first battery I had. I'll try to post pictures to compare the two.
