Hi kids! New device and first time real shopping, got Sony 1800s which fit with adapter, but me wants the biggers! So shopping for 21700s options : iJoy 21700/3750 mAh 40A = 11,95 € ZestQuest 21700/4000mAh = 13,95 € SC 21700/4000 mAh = 11,95 € I'm naturally leaning toward the 400mAh's. But uncertain as to which manufacturer is more reliable. SC is a funny label I find in Germany on many things, the generic (but so far reliable) juices and bases are 'SC' but so are Eleaf mods! Seriously, the Pico box didn't even have the word Eleaf, if I remember correctly [German experts, what's that about?]. I'd go with the obviously more expensive, but given that that isn't necessarily the right criterion... Appreciate the advice!
