Batterries and chargers

[romkush]

Hello ECF forum, I'm new to vaping and ordered a few batteries and I have a question.
The 3 batteries come with 3 types of chargers and I wanted to know if I must charge each battery with its original charger or maybe I can use 1 charger for all of them? The batteries and chargers are:

Joyetech eGo twist 1000mah VV - came with a Joyetech 4.2V 420ma USB charger.
Unbranded mini eGo 3.7v,400mah and eGo K, eGo Q 650mah - come with a 4.2V 420ma USB charger.
SD keyring 300mah - comes with a 100ma USB charger.

Can the 4.2V 420ma charger can be used with the SD keyring? because that 100ma charger is slow.
One more question - can I use a Standard iPhone 5V 1A AC to USB adapter with these USB chargers?

Thank you!

I use my riva charger with my riva, kgo and ego batteries. 650 mah, 900 mah and 1100.

Idk about key ring.

Yes to iPhone charger. iPad 2amp works good too.

Thank you for the fast reply.
Anyone else knows if I can charge the 300mah SD Keyring with the eGo 4.2V 420ma charger?

Recommend just using the key ring charger with the key ring. Don't use other chargers on the key ring, and don't use the key ring charger on other PV.

A general rule of thumb is that you want the mA output less than the mAh of the battery, so you don't want a 420 mA charger for a 300 mAh battery.

Also, even more important, check the SD charger output voltage -- I believe it is 5V output, a mismatch to an ego charger 4.2V output.

Thank you
I've seen somewhere that the SD keyring charger is somewhat unregulated and may overvoltage the battery, on top of being very slow.

I've had my key ring a while, don't use it all that often but haven't noticed any problems with the charger, though I certainly wouldn't use it for batteries expecting a 4.2V charger.

Why? I dont think it's a 5V charger.

Check the charger nameplate. The type size is tiny, but mine says output 5V. I also looked it up online, others say it's 5V.

 

[romkush]

you're right. I'll stick eGo chargers for eGos and charge the SD keyring with the provided charger.
Thanks!

It was a good question. Even within ego or 510 family, there are some oddballs, reverse polarity (positive on the outside of the connector, negative on the center). Hopefully those have gone by the wayside by now, but there may well still be some sold.

Thanks again.
BTW, any idea why I cant post on the general forum? i have more than 5 posts so...

Greater than 5 posts, plus one hour (the database actually updates at 25 past the hour), is when you should have general posting privileges -- PM OldSoldier if it's not happening.

Got it, thanks again.

UPDATE:
Just got a reply from ECigWizzard, they say they recommend using the eGo 4.2v 420ma charger with the 300mah SD keyring eventhough it comes with a 5V 100ma charger. Not sure what to do now...
