Some good discount right there, hope the Vapcell is better than the Xtar(s).

On it's way back to Vampire Vape, charged one set of molicel 21700s and refused to charge via mains lead after that. 2nd time I've owned a Xtar charger, second time the thing had to be returned due to being faulty, the other one was a 4 bay Panzer, back in 2016-ish. Both faulty straight out of the box
I have the same charger but have never used the mains and use usb and no problems, pretty sure i got it from Fogstar but can't remember, did you try with USB, though if it's not charging it's probably cream crackered.
Just for clarity the Xtar is the faulty one, the Vapcell is the one I've just ordered, I like the idea of being able to (also) manually select the charging voltage.I have an extension lead that has 4 Different USB Slots with different Amps, think it goes up to 5 amp. I wouldn't plug it into a PC or anything for the reason you mention. Hope you get it sorted as they are actually pretty good chargers.
I`m almost sure @gary68 has used that supplier.Just ordered 500ml of 7.2 Fairy Liquid from Everything Eliquid, never used them before so fingers crossed.
