18650 Battery Charger Combo 3.7V, VICTAGEN Universal Smart Chargers for Rechargeable Li-ion Batteries 26650 22650 21700 14500 10440 RCR123, Ni-MH Ni-CD AA AAA C

Works great! Feels well made, and charges very quickly.

Quality charger. Display actively shows battery voltage increase in increments of 0.01V up to full (rated) 4.2V for 18650 Batteries separate from the overall charging percentage (peak voltage was attained at around 75% charge). Charger is compatible with certain other standard and exotic batteries as well per included manual. Charging speed is a bit slower with USB 2.1 to micro-USB at 0.5A per each battery, but seems reliable/transparent and batteries don't get hot. Batteries are very high capacity for 18650s at 3,200 mAh. Haven't tested actual longevity yet. Seems like a great upgrade to my diving light kit. Batteries and charger made in China.

So I had been using the Two Battery Victagen with 18650 batteries for awhile. Both batteries lasted in my Nitecore and Streamlight flashlights. I got this 4 port charger for USB-C and for more 18650 batteries for other torches and as backup. However I also got it in hopes of it would charge my Nitecore 21700 which is slightly wider and about 5mm longer than 18650 or about 5 dimes stacked. It does state it supports 21700 batteries but not quite in my case. I tried forcing the Nitecore 21700 into the charger and it nicked the edge of the battery and wouldn't make contact at the positive button side. It needed another 2mm or so to clear the charge points comfortably. It may work with flat 21700s, but I'm not sure. Other than their overlook on taking 21700 batteries, it works well on charging 18650, AA, and AAA. Not sure if they actually charge AA and AAA all the way since I get varying Voltage cutoffs showing on the 2 battery charger version. I usually reinsert the "Full" AA or AAA a couple times till it reaches a FULL 1.45V or above 1.5V shown on the screen. I wished the 4 port version also displays the voltage of the battery inserted while charging. The bright display sucks at night as it is quite bright and stays lit as long as it is plugged in. The next version should include auto dimming of the screen or shutoff after the batteries are done charging. I do like the addition of the USB-C charge port since most of my cords are using USB-C, micro USB is outdated just as much as mini usb!

I unfortunately did not know the difference between flat top vs button top batteries therefore the batteries did not work on the intended application. They do however work in my flash light, and it is twice as bright! The charger works for both styles of batteries and is USB c and micro USB charger compatible which is awesome! Charges quickly and even brought a battery I thought was on its way out back to life. It functions perfectly fine after charging on this charger once.

Updated review... I was contacted by the seller and they sent me another set absolutely free of charge. I received them very quickly. This new set works great!! I guess the previous batteries were just a bad set. Completely satisfied with not only the product but the customer service was top notch Now a 5 star review!! Got these to replace Orbitronics batteries i have been using for almost 3 years. I do inspections for a living and use my flashlight all day. From the moment I put these in the flashlight started blinking and the battery indicator lights were flashing. I fully discharged them properly recharged them and they still did same thing. I found a couple old cheap 18650s I had that had never been used and it works fine. Possible i just got a bad set??? Maybe. Seems like junk to me. The charger is decent to keep as a back up if my nice one dies on me.

I bought a great headlamp at a thrift store and upon arrival back home discovered that it took special batteries. I bought these rechargeable batteries and charger to fill the need. The charger seemed to work well. Unfortunately, I don’t have a good feel for how long the batteries will last, as I’ve only used the headlamp for less than an hour thus far. I’ll update this review when I have a better idea how good they are, and how resistant they are to self discharge.

When I initially received this product I was a bit disappointed that one of the batteries didn’t work. I didn’t even request another battery but they sent me a set of 2 batteries to make up for it. Much appreciated and I actually like the batteries they sent me now, more than the initial ones I requested.. I’ll likely be ordering another set of batteries!

The charger Seems to be working OK as of right now however The issue I have is the outright lie and fraudulent posting of the batteries that come with it. The one and only reason I bought this charger was because it came with two 3200 mA hour battery’s. However I noticed the batteries drained insanely fast compared to my others at 3000 mA hours. Well come to find out they just bought some cheap batteries and wrap them with their own rapper that says 3200 mA hour but in reality one battery is 2500 mA hours the other one is 2600 mA hours not even the same battery. Plus the batteries don’t even last five minutes which tells me they’re very old used batteries that they fraudulently wrapped a new sticker on do not buy this product at any cost. If they’re willing to do this then I’m sure this charger is going to die within a week.

Funciona muy bien, tal como prometieron
