Snado Intelligent Charger, Universal Smart Charger LCD Display for Rechargeable Batteries Li-ion Batteries 18650 18490 18350 17670 17500 16340 14500, RCR123A, Ni-MH/Ni-Cd A AA AAA Batteries (4 Slots)

Last time I purchased this battery charger was back in November 2022, and I have a large inventory of 50 18650 rechargeable batteries and about 25 of the 26650 type. We have around half of the amount of flashlights that we use a lot at work for things related to our job. I always have my batteries ready thanks to these chargers (I say chargers bc I have like 10 of them). It has the options of fast charging (2A), slow charging (0.5A), and medium charging (1.0A). I highly recommend charging your batteries at the minimum Amp if you don’t need them right away, this charger has that option, if need a quick charge, you may use the fast charging set. I have even brought back to life quite a few batteries that were dead after too much fast charging discharging cycles, I simply charged them on the lowest Amp set and voila. I’ve had other brands and types of chargers that really disappointed me, because they either not fully charge my batteries, or had no slow charging mode. If you want my unbiased opinion and advice, get this one, you’ll thank me for that.Pros:- 3 charging speeds modes- There’s a lot of battery types that can be charged with it ( AAA, AA, 21700, 18650, 18660, you name it)- It does not get hot to the touch even if charging 4 batteries at the same time- Able to fix damaged batteries in slow charging mode- If fits any where, making it handy when traveling- Sturdy cable, short though as some has complained about it, but I’m still using the original cable that came with it.Cons: None

I like this as a universal smart charger when traveling, and it has work flawlessly, with one exception that I had to demote the product one star for - safety. While I was able to charge 18650, AA, and AAA batteries most of the time, fast and at normal speeds, the product malfunctioned once pretty bad. I was charging one NiMH rechargeable battery once, and the readout indicated that for that whole time, it was not actually gaining charge. In 20 minutes time, the charger and battery became very hot, and part of the charger began melting and smell of burning plastic. Luckily, I was in the room and safely removed the battery and unplugged the charger. I disposed of the battery, but the charger is partially melted and warped where that battery sat. Since then, there have been no other malfunctions, but just watch this product if you have or end up buying it. Thank you for reading and I hope this helps!

Charge great and simple. Like the LCD screen. However poor material. After 9 months the back split and crack. It probably cause by tension of the springs when placing the batteries in and out. Not worth the $20. Now I have to buy another. Maybe not this one.Update: 1/18/24. a few days ago customer service reach out to me. They were able to send me out a replacement at no cost. Note that I had the original less than a year. They sent me an updated version; got USB-C instead of the mini and the material casing has been upgraded too. No question ask. Works well. Thank you and excellent customer service.

I am using a lot of rechargeable batteries all of which were Ni-MH batteries. I then bought some Lithium AA batteries for motors (shades, locks) but my charger wasn't able to charge those types of batteries. So after doing some research I decided to buy this charger. It handles both battery types perfectly. There are indicators for each of the 4 slots that show how much the battery in that slot is charged. So if one is one earlier then others you can switch in a new battery that needs charging. I am not sure if it can distinguish between Ni-MH batteries and Lithium batteries on a slot-by-slot basis. I usually just charge one battery type at a time. The only drawback is that the charger only comes with a USB charging cable. so you need to have some (phone) power brick to connect it to. In our case we have several 120V outlets with USB charging ports so I just plug it into one of those ports.

I love this charger! I bought it to replace an older charge I had for charging 3.7 volt 14500 batteries. They are the same size as AA batteries, but higher voltage Li-ion. It will also charge the larger (longer) 18500 Li-ion batteries. It shows the rate they are charging at, the current voltage of the batteries, the percentage of charge and how long they have been on charge. You can charge any mix of batteries and as a plus, the charger will also do 1.2 volt Ni-MH and Ni-CD batteries! It has adjustment to vary the current to 3 settings of .5 A, 1 A or 2A so you can slow charge or fast charge batteries. You do have to supply a 5 volt 2 amp power source to utilize it's full potential, but I have used smaller supplies at the slower charge rate. What a great charger for the money!
