Universal Intelligent LCD External Battery Charger Wall Plug Unit 4.2V/800mAh Output & USB Output Port 1300mAh for Samsung Galaxy S3 S4 S5 Note 2 3 4, Edge, Mega etc

Did not work right out of the box. No instructions. I watched several YouTube videos to make sure I was using it correctly. Small electronic items (and even large ones) fail every now and then. Bearing no ill will to seller. Fair return policy. I will purchase a replacement.Review update: changing from 1 star to 2. I bought a different brand to replace this, and in watching a YouTube video for that specific brand got the idea that of the 4 'slots' on my Galaxy S5 battery, insert the prongs into 1 and 3 rather than 1 and 4. Works beautifully. This one might have, too, if they provided instructions.

It works almost as it should. I enjoy the LCD screen that shows the battery in increments of 25%, but the one flaw is that it only charges my Samsung S5 batteries to max of 92%. This isn't terrible as the phone will last all day with minimal use, but I can't use high draw apps or I will be switching to my extra battery before the end of the day. It's strongest quaility is its pins as they are much stronger than the other off the wall charger that I purchased and returned due to the pins falling out. Would recommend to anyone that would like to have a spare battery charged up and ready to go .

A few months after being purchased and used, the continuous "charging" animation partially stopped working -- it still indicated how full it was charged (0%, 25%, 50%, 75%, 100%), but didn't have the animation to indicate if it was actively charging. Yesterday, the sliding mechanism broke and no longer keeps the battery firmly in place, mostly likely from overuse or repeated sliding. It still charges but I had to use a rubber band to keep the battery attached. Still worth the 7 bucks, even with having to use a rubber band. (Delivered Feb 22, for reference)

Worthless, didn't work, no instructions or reset button. Do not buy it.

idnt charge my battery at all waste of money

A good product does its job, but it is so slow to charge the battery, wish the process will be more speedy

It works great. It is a trickle charger. It takes 8 to 10 hours to charge my battery.

Recharges well. I just wish it could be faster. Thank you
