probably the worlds smallest Li-ion charger,USB.

[John]

I decided to try one of these chargers and it's that good it's replaced my two mostly used wall chargers   these are custom built pre-order to your specs,mine is a 90 ma/500 ma switchable USB charger.The 90 ma is good for my 10440 3.7 volt batteries and the 500 for the higher capacity RCR123,18650,14500's in fact it'll charge any 3.7v battery   the cool thing about it is: it give out a volt reading(which is refreshed every sec,so you know at a glance exactly where your battery is at.

Unplugged from your laptop it can be used as a battery tester, some other spec as follows:

Charger details:
The USB Charger is a true constant current/ constant voltage charger. Suitable for rechargeable 3.6v /3.7v li-ions.

* It will taper the current as full voltage is reached. (so you get to 4v quite quickly, and a slower finish to the charge)
* Low voltage protection (will limit current below ~2.9v to protect batteries)
* Thermal limiting
* Reverse polarity protection
* Short circuit protection
* Cut off voltage is approx 4.15v (higher ma versions typically cut off around 4.12v, lower ma versions typically cut off 4.18v)

All I can say this is a breath of fresh air to the normal cumbersome wall chargers I've used,it's much more convenient easily stored and it's travel friendly too as there's a solar panel available which you can plug the charger into,recommended  


The first pic I borrowed just so you can get a feel for how small it really is

So where can one get one of these then?    I have plans for my SF 3P and will need a decent charger.

Is this the Sabrewolf charger John?

I'm using a very similar setup to what MWClint is using in the Sabrewolf barebones sales thread on CPF, but my 4xAA power source is optional/detachable.  It's a great portable solution, but it won't be replacing my Turnigy Accucel-6 for use at home.

Only good for Li-ions mate but yes it's a bit of a animal

It's basically the same as the Sabrewolf barebones unit I built.  The one I have will charge from USB, 4xAA, and solar is a possibility with it also.  This one is cheaper as a complete package, but doesn't charge to 4.2 like the Sabrewolf.

I don't mind that though.  It's easier on the batteries and acceptable for a portable unit.

No! it doesn't charge to 4.2 but rather 4.15 which it's been said before,batteries last longer because of that   yours must be a good charger also otherwise you'd not have mentioned it

I bought the barebones, standalone charger board and put together a system similar to MWClint's setup in post #12 & #14.  I used alligator clips like the pre-made USB unit.

If you're going to buy a complete unit though, I think the one John has is a better and less expensive option.  However, I would recommend removing the magnets and soldering on alligator clips for a more durable setup.
