Nitecore UMS2 vs Xtar VC2S vs Xstar X2 extended version

Looking for a 2 bay charger that has usb capability.

Which is better?

Nitecore UMS2

Xtar VC2S

Xtar X2 extended versio

What do you actually mean by USB capability?

For me, it could mean:

  • the charger is USB-powered (use a USB power source, could be micro-USB or type-C port)
  • the charger has a USB-out port (usually USB-A) to serve as a “powerbank” feature

For a quick list of capabilities, can refer to HKJ’s table of charger reviews here:

also depends on what type of batteries are you planning to charge?
