Is it possible that the strange pulses ar due to a faulty charger ?
Would another one of these chargers show the same strange pulses ?
Have you looked inside to see what chips are being used ?
Great review , many thanks.

No.
Yes.
No, I would expect a microprocessor and a buck converter.
Superb review, thanks HKJ!
For those who want to see the retail packing
Charge using the supplied adapter, Li-ion end voltage 4.19V, while on USB power end voltage was 4.14V, same battery, is it due to my USB power adapter cannot supply enough current ?
Thanks HKJ! What kind of retail price are we seeing on this? Is this charger worth using to measure capacity of Li-Ions? Is the capacity reported close enough to "true" capacity? I realize this won't give us capacity at high discharge currents (i.e. 3A or 5A), but would the stated capacity be similar to a 1A discharge rate capacity?
Thanks,

Thanks for the review. But I miss something in the conclusion about 14500/16340/18350/10440 being charged at 1 A. Do you think that 1A is OK.

So putting in a nearly-charged NiMH risks cooking the cell? or having a power flicker cause a reset when one is almost charged?
NiMH is fairly tolerant with over charging, i.e. I do not know how much damage it does and how this behaviour compares to other chargers.
Thanks alot, HKJ, for another quality review ;)!
Im looking at this as a cheap and portable, no clutter Li battery capacity tester, I know hobby charger would be more versatile and with better accuracy and option, but it will cost more and take up much more space with all the wires and caddies, so Im not sure why would someone who needs only simple testing to make sure their batteries are within manufacturers specifications choose something more complicated and expensive.
Do not expect it to show if a battery is 2500 or 2600 mAh, the actual reading will depend on how much you discharged the battery.
But it will be good to check if the battery has lost a lot of capacity or you got a fake cell.
Thanks very much! Frontpage’d and Sticky’d.
Could you use this charger to tell whether a NiMH cell is weak or damaged?
As long as you always run the cell empty, before charging, the mAh display is a good indicator of problems with the cell.
Would the Xtar WP2 II be a better option than this? Is it true Xtar will be releasing a new version with a display very soon?
That is difficult to say:
Personally I would prefer the WP2, but I can always use some other charger to check the capacity of a battery.
I have seen some rumors on CPF about it. If these rumors are true I would very much like to test it.
How can I measure the charging rate for my chargers with a DMM?
I want to charge My Trustfire 10440 blacks when they arrive.
My charger are the Trustfire TP 001 and Ultrafire WF 139
