HKJ will do you a roundup of chargers for 2018? Or do you think this page is good enough: https://lygte-info.dk/info/roundCellChargerIndex%20UK.html ?

thanks for all the hard work!!

I have never done a roundup of chargers, in late December I do a status where I list some noteworthy products from my testing during the year.

That's what I probably meant.. I thought you sometimes showed a list of recommended chargers...

@Wimpy Water

I’m not looking for a power-bank but a portable/small form factor LSD Rechargeable battery charger, able to use it as a power-bank will be useful/bonus but not a criteria.
Question is….has anyone come across a USB portable AAA AA charger which also acts as a power-bank and charges individual cells. Something like a Xtar PB2 but for MiNh

How do you think about XTAR VC2S?

I do not have anything to say about it yet, but Xtar has promised me a review copy.

Nitecore UMS4

UMS4 is a QC input available intelligent USB four-slot superb charger with a total max output of 4,000 mA and a single slot max output of 3,000 mA.
With LCD display for real-time charging information, it is equipped with a USB charging port for outdoor charging

UMS4

I definitely want to review that charger, but it will first be next year, I have a lot of chargers in queue.

That looks a bit similar to the Nitecore SC4 (SC for “Superb Charger”), except it uses USB Quick Charge voltage to power that charger.

If it’s sort of a modification from the SC4 to adapt for USB QC input voltage, hopefully it won’t have the bugs/”features/annoyances” that are present in the SC4 (the SC4 time-sharing of charging certain slots seems to be also present in other Nitecore chargers; but also in some SC4, the capacity charged display can display grossly incorrect charged capacity results, as mentioned by several user reports when the SC4 is charging all 4 slots, maybe related to the “charging time-sharing”?)

Hi HKJ, hopefully you can fit the Zanflare C2 into your queue.

Probably not this year, I have a lot of chargers in queue at the moment.

How about flashlights with built-in chargers?
Here’s a comment on the charging behavior of the Sofirn SP32A V2.0
that’s currently being offered at a discount (read the first post, email them for a code):

Review Sofirn SP32A V2.0

Thank you for the hint with AliExpress. Concerning the voltage: I’m not saying the charger is dangerous nor safety would be at risk for the battery. Instead, the battery will be worn down quickly for pushing it to/beyond its specifications. It’s not only the 4.21V but also the extreme long CV phase that is applied to the battery. Usually, voltage drops from 4.20V to 4.14-4.16V when charging is finished as the termination phase is rather short.

I like to measure the battery voltage while testing chargers, that is rater difficult on a flashlight without drilling holes!

[hank]

Can a charger that’s capable of providing say 1 amp to a slot somehow detect a smaller cell and reduce the charging current?

[HKJ]

That depends on the charger, some can, either by testing the length of the cell or by measuring the internal resistance.

Some Nitecore chargers do that, I know the SC4 and the F1 does that. I think 14500 or 18350 get 0.5A while 18650s get 1A (for the Nitecore F1). The SC4 also has something similar (check HKJ’s reviews for detailed info).

[contactcr]

Not a huge nitecore fan but the new UMS2 and UMS4 really interest me since it has QC3 input. I really dislike barrel plugs with only 1 purpose when I always have half a dozen various high speed USB all around the house.

Consider this my request for expediting any future QC2/3/PD chargers with that for the INPUT

[Jaded]

Would you consider including the Liitokala Lii-PL4 in your review queue? This model is the same Liitokala Lii-PD4 sans the LCD readout. Quite similar to the Lii-402 which you reviewed more than a year ago.

Not at the current time, I have way to many chargers in queue.
