18650 charger

[TinoZgb]

hello everyone, i hope i am posting this in the right place (if not, can a mod please be kind enough to move it?)

i vape on an istick tc100w, powered by a married pair of samsung 25r (green).
i charge the batteries in the mod, using a phone charger, and i dont vape while charging (well, rarely i do), and always charge them until fully charged (almost, i charged them a couple of times for short time until i would get home, and then charged them fully).
i recently ordered another pair which i intend on rotating with the one i already have (so i wouldnt have to partially cherge).

i also ordered this charger. now, as i read the reviews, i reckon it is a safe charger for these batteries (one pic in the reviews even shows what look like 25rs in the charger).

i know it is cheap, but i dont have the money to spend on a nitecore or an efest charger or something like that. would this charger be safe, or is it better i continue to charge them in the mod?

if posting links to sellers is frowned upon here, here is what they say about it:

Brand: OEM
Type: Charger
Plug: EU adapter
Charging Cell Type: Lithium Ion
Compatible: 18650
Rechargeable Battery Qty: 2
Input Voltage: AC 100~240V 50/60HZ
Output: DC 4.2V=1000mA*2

TL;DR: is this charger safe for samsung 25r (green)?

thanks

I'm very particular about my batteries and I don't want to freak you out so hopefully a guru will come along.

It will do the job but My... £3.38?!!
That's crazy cheap.

But also, did you say you use a phone charger for your mod?
I don't think that's a great idea. I thought all mods had dedicated chargers?
If not, you should buy one from eleaf.

Well mine came with cable only, so i dont think they all have dedicated chargers. And what they advertise on their web site looks like a generic 750mah usb to mini usb charger (like the one i use) , and also a generic 18650 charger.

And thats what i need, i dont need branded or led screen, i just need it to work.

 

[Cheallaigh]

the main issue with using the usb is debatable... but, as far as bare bones goes... it looks like a 4.2 max 2amp charger, which can be okay. i wouldn't really recommend it for long term use.

 

[opticruby]

A Nitecore i2 would be a better option (and probably safer), looks like thay have the new one in stock too.

Of course, if it works, it works.
Just bare in mind that when I personally spoke (via email) to customer service at fast tech, they told me that to use any phone USB plug would be fine to use with the lead they provided. They were wrong, luckily I invested in an external charger regardless.
OEM? I don't know the company, or does that stand for original equipment manufacturer.

But it seems as though you have done your research.
Your house, your rules.

I would spend £12.95 on the d2 I've just seen instead of £3.00
If your batteries are genuine they are probably double the cost of your charger each!

 

[opticruby]

Also the istick tc100w charges at 1A so you'll need a charger rated at 1Amp or higher (just thought I'd mention it).

 

[Psofos]

I wouldn't trust a 4$ charger to charge my 18650s.
You'd be better spending 15$ for a cheap branded and be safe.
Lots of things can go bad,from overcharging-venting-house catching fire,to not charging them correctly and reducing their lifespan.
Charging 18650's should be taken very seriously.

 

[Zutankhamun]

Oh yeah just remembered.

Man, you ain't lived until you've got yourself a flashy led screen!

I'd strongly suggest you get a quality, brand name charger (e.g. one by Xtar). Battery safety is important and I wouldn't trust a cheap no name charger to work properly.

The wall adapter used for charging is simply an adapter. The charging circuitry itself is actually inside the mod. Any charger rated for the mod's charging amps or higher (1+ amps in this case) will suffice.

I agree , i have used Efest LUC models , Nitecores and now the Xtar chargers , anytime a single battery cost's more than the entire charger take a step back and think things over a bit more.

Yep. You're right but correct me if I'm wrong.
If your mods circuitry was to fail, the battery wouldn't complete and instead overcharge? I thought that was the reason we use external chargers?
On top of that, a good quality external charger won't let this happen (or at least less likely) and you can keep an eye on your batteries voltage.

E.g. If your battery is on 4.20 and an hour later the LCD says that your battery is still at 4.20 you have a problem?

I'm no expert, but if the mod circuitry would fail the batteries would most likely simply not charge (of course, the mod could fail in different ways). Personally, I feel that one of the worst things about charging in a mod is that the batteries will heat up more as they're in an enclosed space, and for multiple-battery mods that they might not balance charge properly. That, and the possibility of the usb port breaking and firmware updates therefore becoming impossible. I use external chargers exclusively.

A fully charged battery should stay more or less at 4.2v while on the charger so your example doesn't really work. A battery not charging to 4.2v or close and/or the battery no longer holding the same capacity (remembering that the full capacity is calculated from 2.5/2.8 to 4.2v rather than from the 3.2-3.5v that mods usually switch off at) would be better examples.

Oh I know. Just edited that while you were posting to delete that. I reread it and it doesn't make sense. I rarely use a reg anymore and so I'll only get to about 3.6-7 and then charge.
I use a d4 and I get the voltage displayed but I also have 5 little bars that turn solid (instead of flashing), or when it's the last charge the charger says "end".
So excuse that bad example but I am just saying that if my last bar was continuously flashing (indicating charging) for an hour, then I would feel that either the charger or battery had problems.

As well, I don't really feel that safe relying on a fairly inexpensive piece of kit (which is designed to discharge a battery and heat a coil via a circuit) is necessarily adequate when determining the charge of a battery.

I feel as if dedicated pieces of kit are more trustworthy. Particularly the ones we like to use which are highly regarded in many other forums.

Again, excuse the poor example.

I might use that charger if I absolutely had too. But I wouldn't trust it on batteries that get that close to my face on a regular basis. I would charge in the mod before I would use that thing.

That is just based on looking at the link. No actual experience.

You can get a nitecore I2 for about $12.

 

[Two_Bears]

A Nitecore i2 would be a better option (and probably safer), looks like thay have the new one in stock too.

I would say either get a Nitecore or an Xtar charger.

The jury has spoken, go on a Ramen noodle diet till you can scratch up the cash.
A cheap charger is an invitation to a train wreak..
