Power bank to charge removable batteries??

[degnr8]

I have a 10k mah power bank and was looking at a 20k with solar charging but they all seem to only have usb output and my nitecore charger for 18650s takes 12 volts. Anybody know of a charger that will run off of 5 volt or am I going to have to make one?

I have a Nitecore that runs off a USB cable that I plug into any old USB transformer I have laying around. It has 2 bays and I could run it off my 5k power box I use for my phone and tablet when traveling. Is your Nitecore st up to charge off a 12V car adapter, or did it come with its own wall wart with a custom connection? I didn't think Nitecore made anything but USB cable chargers.

Mine has walwart and 12 volt car adapter. Good to know they make one that will run off of usb. Wasn't looking forward to making one

Lot's of them - preferably not NiteCore. xtar makes at least five I can think off that use a USB power supply, depending on what configuration of features, number & size of batteries etc. you want. www.xtardirect.com
