Why use those instead of 'normal' rechargeables? Invest in a battery charger once and each battery will be cheaper.

The only USB chargeable ones I use are 9-volt batteries, those are awkward and I dont want to replace my charger

"normal" ones are usual NiMH which put out 1.25v. Standard alkaline batteries put out 1.5v.

Some devices care about the difference.

The tiny electronics that allows the lithium battery chemistry to be charged via microUSB also converts the 3.?v output to 1.5v.
