Nice features but no capacity (mAH) defined. I don't know what I'm buying. I do know that I can get an XL 380 mAH KR808D-1 battery for about $10.00 and a mid sized 280 mAH battery for less. I can live without the 'smart' charge indicator. So far very pleased with my
three KR808D-1 stick
batteries, and supply of e-smart clearo's, for quick
ejuice swaps on the fly. Three batts get me though the day and then some.
