UM20 Review by GrimmGreen:
UM20 Charger ~ By NiteCore ~ My Favorite Charger
Review by: GrimmGreen
Pretty much my favorite charger of all time now. I love being able to charge two 18650 batteries and also charge something with a USB at the same time. It’s amazing for travel and doesn’t take up a whole bunch of space. Loads of safety built in including reverse protection and “stop-when-the-battery-is-done”; protection.

NITECORE UM-10 et UM-20 (chargeurs batteries)
Review by: Vap’ed
French vape expert recently does a hands-on review about the UM10 and UM20 chargers that can recharge batteries in addition to a phone or a box thanks to a second USB port. The charging speed and stability is delightful.
