With this power bank I can use one of my Efest 3200mAh 32 amp 26650 batteries to charge or keep my cell phone at full charge.Update, stopped working after about a month.

Great little battery charger

Excenlent. Very good.

Quit working after 4 uses very disappointing.

I really wanted this product,Unfortunately it doesn't work. Instead of 5v it outputs just under battery voltage (about 3.9v) except for a brief pulse to our nearly to 5v shortly after installing the battery.I contacted Civictor who quickly and graciously shipped a replacement.Today I received that replacement and it is just as broken as the first exhibiting the same behavior. Is it me not finding some hidden power switch or missing the magic incantation to make this thing work?

love the unit and the under side cable hidden so the kids don't make off with the charge cable.
