18650 Battery Charger, Dlypow 2 Bays Battery Charger with Auto-Charging Current for IMR/ICR Li-ion 22650 18650 18490 17500 RCR123 14500 and 1.2V Ni-MH Ni-CD AA AAA Rechargeable Batteries

Well built

I've charged several AA and AAA li ion batteries in mix or match trials and all have charged fully with no problems. The only thing I noticed as compared to other chargers I've used is that this one takes quite a bit longer -- like 7-8 hrs for a AA battery -- to charge. I don't have a problem with that, but thought it was noteworthy. The price has dropped since I ordered it (currently ~$8), so I think it's a great value and can recommend it.

Good quality. Exactly as stated

Used these to charge my 18650 batteries without any issue. They didn't take any longer than usual, and seem to be lasting as long as they do with other chargers.Be aware that this charger uses a micro USB cable, which are becoming less common. It DOES come with it's own cable if you don't still have one.

The media could not be loaded. I tested this unit with an Li-ion 18650 battery. The red light started flashing (see video) which is an indicator of wrong battery type, bad battery or wrong polarity as per manual (image attached) which is definitely not the case. The battery I used is fully functional and 18650 type is mentioned in the manual as well. I would not recommend this product.

This charger works great and can charge batteries from sizes AAA all the way to 18650 batteries. I love the versatility between battery ranges. It is built sturdy and only takes a few hours to charge. The batteries can be charged separately so that is really cool, most chargers make you charge 2 batteries in order to work but this one lets you charge 1 at a time or 2 at a time. I think that this device comes at a great value for the quality and functionality. I would recomend this item.

When I’m traveling in my camper van it’s nice to have a small charger for my flashlight batteries. I replaced one that charged a single battery, but all of my flashlights use two batteries so it made sense to upgrade to a double. This one works great and charges up my batteries just fine.

This DIYFull battery charger is a simple 2 battery charger that works fast enough (a couple of hours) to charge 2 18650 batteries. It is very versatile as it can charge large mAh 18650s down to diminutive AAAA batteries. It comes with a USB-A cable so you can connect the charger to your PC or a phone charger (not included).If you need a relatively fast charger that is able to charge AAAA up to 18650s, this charger can do it.
