Just saw this highly recommended battery charger on sale. Especially useful for bigger 18650 batteries used in high powered LED Flashlight or Vape products.
Works with:
10440/14500/14650/16340/17500/17670/18350/18490/18500/18650/18700/22650/25500/26650/32650 3.6V/3.7V Li-ion and AAAA/AAA/AA/A/SC/C/D Ni-MH/Ni-CD batteries
For you to get an idea. This here is an XTAR VC4 vs Nitecore D4 comparison on video. I own the Nitecore D4 myself but not the VC4 so i can't comment on the VC4. I think the Nitecore D4 may be a better charger in some scenarios.
