Nitecore UM10 Mini 1-bay USB Li-ion Battery charger
This is a cool little travel size charger. This is great when you need a stand by battery for your V3 and V4 Henail and never have wait to dab on your Henail, always have a fully charged back up battery ready to go. Charges a single battery at a time, but it’s small enough to even keep in your pocket if you wanted to. It works off a USB port. Can charge most common cylindrical batteries like 18650and 18350 (full list in the specs below).
Allows pretty fast charging, with 0.5A and 1A modes.
Includes USB pass-through as well so that you can plug another USB device into the UM10 so you don’t have to worry about running out of USB ports.
Is made to be very portable, including a internal cable winder so the cord is kept from tangling with everything.
Anti-counterfeit validation code is on the package so you can be sure it’s genuine Nitecore.
