Universal Battery Charger EASTSHINE S2 LCD Display Speedy Smart Charger for Rechargeable Batteries Ni-MH Ni-Cd AA AAA Li-ion LiFePO4 IMR 10440 14500 16340 18650 RCR123 26650 18500 17670 & Car Adapter

I now own 2 of these. First one still in use and works great. Bought a second one as I have a lot of 26650 batteries. Great product!

I ordered two of these for reasons I don't remember. I opened both immediately and charge some batteries. I wanted to ensure they worked. I have two lights that use 18650 batteries. These are Liion batteries. These multi-size chargers have a sliding bar at one end so they can take various batteries. I find that if you pull them back with your fingers and insert the battery, they work better than trying to push them back with the battery. They will slide more easily and you are less likely to damage them. This charger was easy to connect the battery. Some chargers are hard to get good connections. I did not have any problems with this unit. They immediately measure the battery voltage which determines the battery type. Note that if you are charging LiFe batteries, you have to press a button to set that type. The voltage tells the charger the battery type because the maximum voltage for NiMh and NiCd battery maximum voltage is less than the minimum for Liion. If the battery is excessively discharged, It may start as a NiMh or NiCd battery type. The charger defaults to 500mA charge rate and you can press the button to select 1A. I left the current at 500mA. Charging slower is good unless you are in a hurry. The display alternates between the voltage and the current during the charge and a timer shows how long the battery has been charging. A display of a battery with bars shows the state of charge. All the batteries charged as expected. They were at different charge levels and they all charged correctly. The charger stopped the charge cycle when the battery was full. The display was easy to read and the information was also easy to understand for me anyway. I charge a lot of batteries and use a number of different chargers so I am very familiar with them. This look like they work OK and I hope they last. I only used these on AC power.

Good recharger, takes about 3 hours , made well, comes with car adapter

I've had this charger for around 7 years and it works as good as it ever did -- which is pretty good, overall. It will charge a great variety of battery types and gives you a good idea of what is happening and how much things have been charged. My only gripe, with the product I have at least, is that if your rechargeable battery is drained to the bone (like, say, it was powering a flashlight that had been left on) the unit may reject the battery, telling you there's an error, and there's no way to convince it to charge the battery unless you first charge it at least a little in another unit. And once it's in the other unit, there's not much point of transferring it back to the EASTSHINE. This is a pain and means you need an auxiliary unit. Worse, you may become convinced a battery is dead prematurely, and throw it away, even though in most ways it's as good as ever. Indeed, this can seemingly happen to any battery, old or new, so long as it has been completely drained. Also, it does not charge D batteries -- which I knew ahead of time, so... can't complain, right? Would I buy it again? Well, I'm glad I bought it originally, and like I said it still works fine, but given it's drawbacks I think when I replace it I will purchase a different model.

I've had this for 2 yrs now and love it. I use it almost every day to charge batteries for my headlights. It does a great job.

I bought this specifically to charge rechargeable batteries meant for an old Sony Walkman from the 90's. Specifically, it was a HQRP battery that's compatible with devices taking Sony's NC-6WM battery which I don't believe is made anymore. Even though the listing says it takes cylindrical batteries and stretches up the C size, it looks like this can stretch to fit D sized batteries and it will hold and charge a gumstick battery like the NC-6WM just fine. The only thing to look out for is that the original batteries were supposed to be charged at 100ma but this charger only does 500ma or, if you turn on fast charging, 1000ma. Newer NiMh batteries should be able to take the the higher milliamperage just fine like the ones I got from HQRP here on Amazon but even if it isn't supposed to be charged at 500ma the only negative result would be that you get fewer charging cycles out of the battery which isn't that big of a deal considering you can get replacement batteries pretty easily and newer NiMh batteries are all made to handle the power coming from these new universal chargers. The car adapter is nice but not useful for me. The display is super helpful for seeing how much power is going into the battery, what the power output of the battery actually is, how much time the battery has been charging and it'll show you clearly when the battery is charged and how full the battery is. It's a simple, good overall universal charger. The charger will also automatically shut off if your battery takes more than 8 hours to charge which may be a good thing and the safety features all seem to work.
