VidProPT-UNV Universal Li-Ion Battery Charger - Adjustable Programmable Travel Friendly Charger with Overcharge Protection and Automatic Polarity Detection Compatible with Most Battery Types

It works well. I was able to charge 2 of my batteries for my original 3DS. Let’s see how long this will last.Update: i tried to charge the batteries for my samsung galaxy avant phone from when i was in 9th grade back in 2015, and the phone turns on but, does nothing else :(

It does what it Says

Excellent product, but due to the varying design of camera batteries, this doesn't work with every brand, even if you're careful to align the positive & negative contacts.

My game boy advance sp charging port is jacked up. Removed the battery and purchased this charger hoping it would work. Glad to say it worked on my battery perfectly. I do want to add that my gameboy is using a Nintendo DS battery so results may vary.

This worked great charging my husband's cellphone battery. I can't wait to try it on my camera battery. Easy to use.

did not work!

Since this basic dimension isn't included in the description, here it is: the adjustable clamp opens to a maximum of 82 mm. It's the only charger I could find that holds my device's large battery. It charges that particular battery to ~80% (light never changes from red to green, so you need to put the battery back in its original device to check the charge level). Does not come with car adapter or EU plug adapter.

It works, with caveats.I've used this a couple of times to charge batteries for my Moto E6 cellphone. It does work. A few things to think about:1) This battery is about the longest that will fit into the mounting bracket. A Motorola KE40 battery.2) This is a universal charger and you must slide the terminals to match the battery. This can be tricky, or fiddly as the Brits say. You have to pull back the spring loaded mounting bracket, hold it there, and slide the battery in so it matches the sliding terminals, then let the spring loaded bracket go slowly. You may have to move the battery off to sone side so you can hold the spring loaded bracket with one hand and the battery with the other hand. I find it easiest to mount the battery then plug it into an outlet.3) This is a slow charger. It works at about 600 ma. It takes about 5 hours to charge a 2500 mah battery and ends up about 4.2 v for a single cell battery. The labeling says it will also do 2 cell batteries, which end up at 8.4 v. It has a light that's red when charging and green when charged.4) The terminals blades that contact the battery are very thin and may break or bend in the future. I haven't used it long enough to know. You should make it a point to be very gentle with them. These blades are also moderately sharp and may scratch the battery terminals a bit.5) The spring loaded mounting bracket can be rotated 180 degrees to accommodate shorter or longer batteries.6) It did not come with any external power adapters nor instructions.Overall, a good product and usable if you're careful. No idea about long term longevity.Ron
