I just had an idea so im wondering if there are any out there already … or if its even possible?
What im thinking of is a Li-Ion batteriy charger that also has a USB output so you can put fully charged batteries in it and use it as a portable battery pack for recharging phones etc. They have them on flashlights now so why not a charger where you can strap in 4 fully charged 18650’s etc
I think i’ll definately grab a couple of those ML-102’s … but i was having a look a t a few others and really liked the design of this one (mainly due to the closed design and being able to handle more than 1 batt.
ML-102 can do that, fits up to 70mm battery though it is a tight squeeze. 68 is fine.
If you want more power just look for some battery packs, cases that hold batteries and have the USB out, and hopefully also USB in for charging the pack.
