I have the XTAR Dragon, but what back up?.

Is this common with this charger ? I’ve left chargers on overnight & they’ve been fine.

I have 12 chargers from different brands. None of them have overheated or even got more than lukewarm from leaving them charging overnight. That said, I’ve been charging Li-Ion batteries since 2011 with no issues at all. One other thing, I only buy name brand batteries from reliable USA sellers.

I would recommend getting a Folomov A4:

Can charge cells at 2A/slot maximum, and 3A/slot if you need it for large 26650/21700 cells or fast charging.

Has support for 21700 flat tops, LiFePO4 charging, etc.

An all-around excellent charger.

Guess I’m not as fortunate as some.

And XTAR actually warns against leaving cells in the Dragon charger overnight?

I guess that’s not just a lawyer-type caution.

Scary.

I like to have a charger on 24/7 and always there is at least a Sony VTC6 (for ecig use) charging (one I use, one I charge and a few more are charged backups).

Using chargers 24/7 had its downs in the past and, since 2007, I have killed (each after 6-12 months use) these chargers:

  • 2 * XTAR WP6-2
  • 2 * Nitecore 4 slots (one with LCD screen, one with led lights)
  • 3 * Trustfire TR-001
  • 1 * Ultrafire WF-139

For the last year, I am using one of my six Lii-402 24/7 without problems and I keep the better ones (Opus BT-C3100, Miboxer C8, Lii-500) unplugged until I need them. Using Lii-402 as my main charger was decided after making the thought that “no charger, cheap or expensive is going to last 24/7 for more than a year, so better burn cheap but reliable chargers”. And Lii-402 is cheap and reliable.

So, my opinion is get a few Lii-402, use them all the time and keep Dragon for stuff other than daily charging.

thanks , what is the Miboxer C4-12 compared to the dragon?.
seems many like it.

It’s a good charger, if it’s within your budget. The only potential issue with it is the auto current rate selection based on measured IR. This is a hit or miss, in my experience. Thankfully, you can always override the auto rate with a manual setting, but you have to remember to do that.

You haven’t specified a price point in your OP, so I figured you were looking for something inexpensive for backup, so that’s why I suggested Lii-500 earlier. The ability to measure capacity is an added bonus, IMO.

I looove the C4-12.

Its DC internal resistance meter is accurate for a charger(although not as accurate as a constant current load).

It can charge stupid quickly cells. It ends the voltage right at 4,20V.

It supports 21700s, although not protected ones.

It’s the only charger that I have that can super fast charge 14500s if you need to.

AA as in NiMH, or AA as in 14500 Li-Ion?

Max current for NiMH is 1A - not super fast, IMO.
And as for charging 14500 Li-Ion, you probably don’t want to charge them faster than about 0.7-1.0A anyway.

Sorry, I only have a 14500 cell, and mistook it for an AA cell.

for backup just get something 2 or 4 cell and cheap

many lights are now coming with built in charging, so that is ‘backup’ if you have those

wle

I wonder if the A4 currently fits 21700’s better than the two I have…? maybe mine are old…
The Sofirn cell I had, had to be forced in, as does the 50e cell I have…To the point that the wrapper was getting messed up.

That’s the reason I hacked part of my case, to the amusement of some….

Other than that, I agree it is a great charger, esp at $25 on your link… Can do 4 @ 2 ampsper, or slot 1 and 4 (2 cells) at 3 amps per … :+1:

Hope that youtube guy doesn’t get hold of one. :laughing:

Oh. Unless you only use flat top 21700s, I would recommend getting the Miboxer C4 Plus/C4-12.

The A4 only supports up to 70.1mm cells.

Are the button Tops longer?
The sammy 50e is a flat top and doesnt fit to my liking …

Sounds like a mod to me :wink:

got this in the end.

thank you.

I got both Xtar VC4 and VC2. Happy with both.
Unfortunately they don’t do Li-Po4.
so I bought a cheapie little Lii-Kala 202 WHic.
I’m also very happy with. Have left then all on overnight at some time or other
with no problems. So far.

For just basic charging. either do a good job at a good price.

XTAR VP2 Charger can charge LiFePO4 Battery: Amazon.com
