Thanks wshyhang!
It is my understanding that the intelicharger is safe and does charge AAA batteries, but you have to charge 2 or 4 of them at once to reduce the charge imput to a safe level for AAA batteries. Says so in the instructions. Or charge them along with other batteries in the charger. You will need a battery in #1 and# 3 or # 2 and #4, or one battery in all 4 slots if charging AAA batteries. I have charged some with no problems that I can tell. I am happy with my Intelicharger so far.
I have got some 15270, CR2 from FastTech and realise that none of my chargers fit!
Would this charger be able to charge those CR2?
The batteries have a warning label on other side saying, “The voltage of full charge and empty condition is 3.6V and 2.0V respectively”.
No, the charger must be marked 3.0 or 3.2 volt.
Thanks HKJ for your very fast response! :bigsmile: Two quick questions (sorry for hijacking the thread). Which charger would you look at if you are charging CR2? Also I have the TR-001 and planning to charge those CR2 using magnet spacers in TR-001 at the 3.0V option, would you recommend it?
That depends on the chemistry of the cell, I believe yours are LiFePO4 and I do not know a good charger for that.
For LiCoO2 I would look for a CottonPickers charger or modify a TP4056 module.
I do not know much about the TR-001 (I will probably know more in a couple of weeks).
My guess is that it will work fine, but the charge current is probably to high and might increase the wear on the cell.
Thanks very much for your professional advice once again. Probably would try it.
By the way just a compliment. I really enjoyed your reviews (though I don’t know much how to really interpret the diagrams) of chargers, batteries and also flashlights. Amazed by your extensive collection of batteries, and small flashlights 
Can it do 26650 and 18650?
If you read the review that starts this thread, there is a table with the answers:
So can the Xtar SP2
Just received this charger from Fast tech and the included wall charger states the output to be 12.0V - 0.5A. Should the output not be 1A? Soshine packaged Huawei switching power adapter model HF-120050U3.
Why?
If it had uses a linear regulator it would get very hot.
When using 12 volt input, it is most common to use a buck converter to reduce voltage and this will increase current.
Thanks for that helpful explanation. Even when I think I am gaining an understanding of a certain aspect, I find there is lots more to learn.
The Soshine SC-F3 also has this faint clicking. It can also be heard whilst charging.
Good review and discussion. I ordered one on AliExpress.
I plan to use USB power to charge my Li Co non-IMR 14500s, the peak power is low enough and I don’t think starting at 0.8A average will hurt them.
It appears to me to be very well designed and maybe better than the Xtar WP2 II, if the quality is as good. The pulsing after charge is complete to maintain voltage seems a good feature, in case one wants to leave a cell in the charger to have it ready at maximum charge. The reduced charge rate as the voltage rises with USB appears to be to avoid overloading the USB port. The only thing I miss is an option to charge to 3.9 or 4.1 V, which may extend batter life. (At least some hybrid cars don’t fully charge or fully discharge their batteries, in order to extend battery life.) As it is I can only do this by watching the voltage LCD display and taking it out.
Thanks! Ordered one of these, as I was looking for a USB powered single channel NiMH AA charger for a bit. Seemed to fit the bill. Have also wanted to get a rough capacity measure on my 18650 laptop pulls, so seems to be a win win.
My new SC-S7 seems to consistently only charge Li-Ions to 4.16v. The voltage on the display (though only shown to a tenth of a volt) always seems to read slightly high. Other than that is seems to be working out well for me. You do have to be careful not to knock the battery out which will cause you to lose your "mAh charged" data (I know from experience).

I’ve been putting the cell in, slide the neg term up to it, take the cell out and then carefully push it one click shorter - battery fits nice and snug… YMMV
