The flashlight feature is actually a welcome addition! I get several phone charges out of these. Used one to provide external power to my bike computer during an endurance event and it handled it without fault. Two charge ports are quite convenient.

Maybe a little bulky? Would prefer a more rectangular shape for easier stacking...

These are great. Picked two up for 9.99 each and they have worked flawlessly for me thus far. The flashlight was a surprising bonus when I went camping and for late night trips to bed in the dark. Honestly, simple straightforward reliable product. Great value imo, would buy again!
