Nitecore F2
Nice charger/ powerbank. One nice feature of this charger is that it can charge and discharge at the same time (pass-through charging), which is good for solar charging. Even with the solar panel varying in output, the F2 powerbank charging will auto start after being in the shade, as opposed to some other powerbanks where you will need to take the plug out and restart it. The current input is a bit much at around 1.8 amps, but is meant for faster charging of higher capacity cells, but can also run off much lower current like 500mA from usb2. Also charges the cells individually and not as one which of course is the proper way to charge two cells of different charge levels and capacity. I secure the batteries with velcro instead of the rubberbands which is faster. A very useful item for camping or backpacking. Recommend using 3600mAh 18650's. I drilled a couple holes for threading a loop, in which I can hang the powerbank and a led light which makes a great compact lantern.
