## Questions & Answers

**Q: how long charge?**
A: Charge until all of the bars (in display window) are continuously lit up and the "in" volt should read about 5 volts  but more importantly the "in" current will read zero. The amount of time it takes to reach the fully charged state varies drastically depending on the charger you use and also the capacity of lipo batteries that are used. Mine takes a couple of hours to charge and I am using 4x 2000mah lipo batteries with a USB 2.0  2 amp basic wall charger. Hope this helps.

**Q: Will this also charge Cr 123a if you stack 2 together**
A: No it will not fit. Only 18650!

**Q: Does it charge the batteries independently? If I replace one full battery with a dead one, will it charge just the one dead battery?**
A: Yes, and you can see how full each battery is

**Q: Can this use a solar panel to charge?**
A: I dont see why it wouldn't work with solar charging
