Slot LCD Fast Intelligent Battery Charger SD4

11/06/18 After posting a 1 star review on this product, I was promptly contacted by a representative. They mailed me a replacement and requested I give a 5 star review for this purchase. I've been using the replacement item for a few days now, and it has been able to fully charge my 18650 and 18500 li-ion batteries to 4.2V. I am not giving a 5 star review for this item because the quality control needs work. If you need a cheap charger for some li-ion batteries and you happen to get your hands on one of these charges that work, then this is a pretty good deal!--original post--I bought this charger to recharge a few sets of brand new 18500 li-ion and Samsung 18650 Q30 li-ion batteries. It charges for an indeterminate amount of time, and then jumps from 25% to 100% complete. Upon checking the voltages of the batteries, they are still 3.7v. A fully charged li-ion battery should be 4.2v. I plugged the batteries into my keenstone C1-xr charger, and it charged them up all the way without trouble in about 45 minutes. Don't get this charger, seems a good way to ruin a set of batteries which were likely worth more than the charger itself.

So far I enjoyed this charger. It has the ability to charge AA, AAA, and also 18650 cells all at the same time. I just bought it to charge batteries for my demo vaporizers but it turns out that it also charge my batteries for my Xbox controllers and all at the same time and that is great. Added bonus. One thing I did notice that in the instructions it said to use the charger that came with it and it did not come with a charger. It came with a charging cable but not the box part of the charger. I don’t know if that was a mistake and packaging or if it was a mistake in the manual but it seems to work OK with my higher powered cellphone chargers. I would imagine it would work off of any USB source. I really like the display and the fact that it tells you what each batteries status is. Very nifty device for the price. If it breaks in a short amount of time I will get back on here and re-review it.

The charger we received originally was defective, but the seller was very quick to replace it - and the new one works wonderfully! Very fast shipping and excellent customer service! (Bad products happen - it's the desire to do the right thing for their customers that makes a difference!)

A bit disappointed in that it only comes with a USB cord and I have to supply my own USB charger to attach to the 3' USB cord supplied. I was hoping it came with a normal plug to plug into the wall as some of the reviews suggested it might have. Not so. With it's limited power input, I'm not so sure this will charge very fast.

Great for 18650's not so great for 26650 batteries26650 batteries stopped charging after a month of use

This item was perfect. I travel and use a power bank for all my needs when away from a mains outlet. So to find a charger I can plug into the power pack was fantastic. The product itself has great charging displays which are a lot easier than the previous chargers I've bought.

Not exactly as described, but it does what it says it will do. I have not been able to figure out how to select the charging rate yet. Unknown on durability at present. It does give you a reading of the batteries(individual) charge status. Seems OK

The outside slots work, but you have to wiggle the battery to get a connection. The two middle slots won't work.Update: the company immediately contacted me after seeing my review and offered to take care of my problem. That is great customer service and worthy of 5 stars!
