So I have a 1000mah Joye eGo Twist. It takes a solid 6 to 7 hours to get a good charge, despite the fact that the charger says 420mah right on it. I know this isnt right, but does anyone else have the same sort of problem? Maybe with a different battery? What charger should I buy if Im looking for a quicker charge time?
First thing is do you clean the contacts on the charger dongle? Little bits of juice on the battery contacts could accumulate on the charger. Mine gets pretty dirty after a while.
But, also, the wall adapters are a little on the iffy side apparently. I've run into them going south on people more often than they really should. I looked at mine today (while talking to somebody else on the forum about this exact same problem) and the output on my Joye branded wall adapter is only 500mA. That doesn't leave any room since the charger dongle's input is 500mA. So the wall adapter is running at capacity all the time. That bothers me. It's not a good idea.
You could try moving the charger dongle to a powered USB port (such as actually on the computer or a powered hub, unpowered ports such as on a keyboard can't drive the chargers). You could also do what I did, nab a USB wall adapter that has more capacity such as:
AmazonBasics Wall Charger with USB Outlet (2.1 Amp Output). 2.1 amps is 2100mA which is four times what the charger dongle needs. So the wall adapter isn't running "full tilt" the whole time. And, anyway, back ups are always a good idea.
Though, now, if your batteries are older, they do age (don't we all?

). A new Twist should charge in around 2.5 hours (ish). Mine are taking up to 4 now. But they've seen pretty heavy use...
