Looking for a good (USB) charger with low charging current

Hi guys,

I'm looking for a good charger with following specs:

  • selectable low charging current, i.e. minimum current should be 100mA or even less.
  • slot size should fit for 10180, 10440, 14500 and 18650
  • USB powered would be a benefit but not necessary

Any recommendations? I want to use this one to charge batteries for the Ultratac K18, Acebeam UC15 and the Klarus TP20 Ti. All these batteries must not be charged with more than 0.7C, i.e. less than 250mA for 10440 and equal to or less than 100mA for 10180.

Thanks for your feedback!
