18650 Battery Charger with Testing Functions, POWXS Universal 3.7V Charger for Li-Ion Rechargeable Batteries IMR Lithium 26650 21700 18650 16340 14500 10440, Ni-Mh/Ni-Cd AA AAA C Batteries

At first I intended to return it since many batteries are not on the list but I went ahead and used it and works perfect. price is VERY good. It is very useful if you want to recharge such as high powered flashlight batteries and dont want to have to use the lite to charge. (then you cant use the item) This charger WILL detect and properly charge the RECHARCHABLE batteries and scrolls through a list telling everything about the battery as it charges. classic example is batteries for tactical flashlights. I intend to upload a youtube review raving about it.

My opinion, it charges faster than the other chargers I own.

I have had mine for quite a while now. Still works great. My only issue is certain batteries are given the wrong type which if not watched can cause major issues. You can only change the type of it is lifepo4 or 4.35v lithium. Sometimes it labels regular lion batteries as nimh/nicd. There is no way to correct this. Also my charger is in my work area and gets dirty and now the slides to insert batteries are difficult to fully extend to fit battery. In the positive i have gone thru 4 other testers in this time and all have crapped out. This one is still going strong

Would recommend this item.

The media could not be loaded.  I bought one of these a while back and it didn't last but a couple weeks so they sent me a new one and it did the same thing as the first one. The first Bank just randomly quit working. The battery percent level bounces all over the place and it acts like the batteries being taken out and put in every 5 seconds. It was working great and all of a sudden it started getting hot so I took the battery out before it ruined it and now it does that. Bank 2,3, and 4 still work just fine. It sucks because Bank One does the 2 amp charging and obviously I can only charge three at a time now. I thought I sent this review months ago but I guess it never sent and I noticed it just now.

The media could not be loaded.  This is a generic 3.7V charger that I needed to recharge 18650 batteries for my tactical flashlight. It comes packed with fancy features like showing current charge level, charging voltage and amperage, allows you to choose charging current, and many others. It's a very straightforward and simple to use fully automatic charger - just insert a battery and come back when it's ready. It automatically identifies battery chemistry (Li-Ion, LiFePO4, Ni-MH, Ni-CD) and chooses a proper charging mode. The LCD is large, with a backlight, and is easy to read. The coolest "advanced" feature is its ability to test batteries and estimate their real capacity, which is especially important for old batteries to know when to retire them or for batteries made in China with unrealistic capacity claims stamped on them :). The only feature I'm missing is an ability to run a refresh cycle to "unstuck" old batteries and push capacity to their limit that some even more advanced charges have.There are four battery ports, and each port features a spring-loaded contact that allows different lengths of batteries to be inserted, that's why the charger is suitable for such a wide variety of batteries. Basically, any battery of 3.7V, 1.5V or 1.2V and Li-Ion, LiFePO4, Ni-MH, Ni-CD types can be charged in it. I tried it for my 18650 Li-ion batteries, AA and AAA NiMh, and I even tried it with the new type of AA/AAA batteries Li-ion 1.5V and it worked as well! Looks like it can charge absolutely anything I throw in it, which is cool. Said that, it works quite well, does what it is supposed to do, power off from 110 VAC wall outlet or you can connect it to 12 VDC power source (like car's 12V cigarette adapter). Unfortunately, there is no 12 VDC connector provided, and I don't know how to get it, so this 12V power option is useless.One thing that I did not like is the buttons and user interface. There are two tiny buttons below the LCD display, which you probably will not see if you don't know where they are. One lets you select a battery slot and another one allows you to change the charging current. They are hard to press, and they are inconvenient to use. By default, charging current is 500 mA, but I prefer 250 mA to extend battery life. You can't select the charging rate for all slots at the same time, you have to meticulously scroll through each of them with button #1, then press button #2 to enter setup mode and then scroll again through all charging currents until you find the one you need. Gee, this takes time. And once you remove a battery, its charging mode resets back to the default one, and you have to repeat the whole procedure. This really needs to be improved.*** TL;DR ***Yes, I would definitely recommend this battery charger, it really works for every type of battery existing on the market. It's a little bulky compared to other chargers I have but it can be powered directly from 110 VAC outlet. The only issue is the very inconvenient user interface with two tiny buttons. But it works great otherwise. Therefore, I am still gonna give it 5 stars, I like it!+++ Pros +++1) Works for 1.2V Ni-MH Ni-CD batteries.2) Works for 3.7V Li-Ion batteries.3) Works for 3.2V LiFePO4 batteries.4) Works ever for 1.5V Li-ion AA/AAA batteries!5) Fully automatic.6) Can estimate battery capacity.7) Simple to use and efficient.8) Very large backlit display.--- Cons ---1) Requires 110 VDC power source.2) Large and bulky.3) Can't run a battery "refresh" cycle.

Overall, a very powerful and informative charger.A small design issue: I didn't like the plastic adjustment holder for AAA batteries that comes with it. Many other chargers can do without it. It's flimsy and may be easily lost.
