Nitecore UM10, D2, & D4 Lithium Ion and NIMH Battery Charger Overview and Comparison
This is an overview & demonstration of the UM10, D2 and D4 Nitecore smart Lithium Ion battery chargers. The UM10, the D2, and the D4. The UM10 is a USB based smart charger which works with lithium ion or IMR batteries. The D2 and D4 Digicharger are universal chargers that will charge multiple battery chemistries including NiCad NIMH, and LiFePO4s. While this isn’t a full review, I go over the differences, and features, and try not to put you to sleep. But I probably will.
