Most of the time I have old cell, but how old varies a bit. With LiIon the 18350-IMR has been used for many years on all chargers. With NiMH it is usual a 2500mAh cell that gets old.
Yes, I know that, but I do generally not now which chargers gets updated.
I do usual not ask manufacturers or dealers for chargers, the contact me with the charger they want tested.
That is the first time I hear about more updates (I do not check around for new versions), but I do not have time to check it now. I have a couple of chargers and some manufactures has told be I can expect more very soon.
Thank you so much for indicating which chargers can also be used as power banks in this tabulated data! This is a feature I am currently researching and you are making my job much easier.
One small thing that I could suggest is that the provided links to each charger open in a new window versus inside the table space. This provides much more viewing room for the charger data and allows multiple chargers to be compared, each in their own window.
All of this work you are doing for us is incredible! Thank you!
First, allow me to thank you for making those comprehensive charger reviews, despite the fact that sometimes, there may be new revisions that may warrant a re-test of that specific charger (only functions that changed, but may not be easy to identify without a complete test…).
I would like to mention there seems to be an inaccuracy in the table — the Miboxer C4-12 is listed as an “analyzer” — AFAIK, it does not do discharge testing, so it’s not an “analyzer”.
am trying to find a charger for my 18650’s using your “table of tested chargers” but am having a problem using it.
Under the “select index”…… I can NOT remove a search option, once I click on it.
For example, say I click ‘LiIon only’. It (the text) turns red. But then if I want to search ‘NIMH only’ I try to get rid of the ‘LiIon only’ by clicking on it but it just stays red and is still included in search.
The only browser I have is Firefox. Does the page only work on IE?
It works with Firefox (I am am using Firefox).
I do not know why it turns red, each index is a separate page and when you click on it you simple changes to that page. The title shows what page you are on.
OK, so a nice feature would be for it would be:
Able to search multiple features at one time. In other words…. (as in my case on the “search index/options”), I would press the LiION ONLY, DISPLAY V and mAh, 12v Power Imput, 2 slots, (options) and the resulting page would only show chargers that have all of these features…since those are the features I must have in a charger.
That is the way I was trying to use your informative index (my bad) since most search charts work this way. (Parametrek Batteries)
Just a thought, thanks for all your hard work and info !!!
You can search on two parameters, the first is select the best table, the next is sorting a column. If you select the right parameters the remaining list will be fairly short.
Parametrek is something else, is uses a database, my list is just a html page. I have found a script that can filter on each column (tablefilter.js), but it cannot sort. If anybody knows a free javascript library that can do both, please say.

HKJ, what’s your favourite charger in 2019? I would like to test mAh, charge 2/4 cell, display.
I have single cell tp4056 charger, 4 wire battery holder, skyrc b6 mini, zb206 battery tester, but all these can charge/test only one cell. I am looking for a decent charger in the price range of 20-30usd.
I have only published 7 charger reviews in 2019 and only two of them are 4 slot with mAh display and only one of these has adjustable current, that is the Nitecore UM4.
If you want to discharge batteries to measure them, the Lii-500 and BT-C3100 are still good cheap chargers.
