usb and wall adapter charger question

[Sqhertz1]

So, i have a 500 mah wall charger that came with my eRoll kit and a 420 mah that came with my smok 900 mah ego batt.

Can i safely use the USB with the wall adapter for the 900 mah battery? What about the same combo on a 400 mah vision?

Thanks in advance!!

Yes the wall to usb is universal. Just plug the USB in and charge it up. If the usb you are using came with your kit, you should be okay. If you got the usb's seperately I would suggest googling the brand to make sure it has the safety mechanism to prevent over-charging and fires. Most chargers have this mechanism, so I seriously doubt you'll have an issue.
Happy vaping!

The USB came with the smok ego kit and has the red/green led. If that matters any.

The wall adapter is just to provide the 5V input to the charger, and as long as it's output rating is the same or higher than the rating on the charger, it's fine to use.

You say your charger that came with the 900 is a 420 mAh device, and your wall adapter is 500 mAh, so should be good.

The wall adapter is so you don't have to plug the charger into a computer's USB port.

Makes sense, thanks.

I'm guessing the 420 charger would be too much for a 400 battery...

No, that's fine. But don't use it on the stick batteries, get a 200 or 150 mah charger for those.

I use a 420 on 1300 and 900 Spinners and on an old 350 Ego (backup for backups!) with no problems.
