This is a great product! It works for many batteries, does a fast charge, stops charging (so protects your battery) when it's full. Very good value!No instructions included. You have to set it to your particular battery. Here's how:1. Look at your battery. Find where the + and - points are on it. They should be marked, inside little circles.2. Look at the charger. To fit in a battery, you will have to pull firmly, sideways on the spring-loaded door.3. Put the battery in the spring-loader, with the metal contacts facing the pins, but not up tight. Leave a small gap.4. SLIDE THE 2 CHARGER PINS so they match up with your + and - contacts exactly.5. Push the battery up against them.6. Plug it in. If the light is magenta (pink-red), your battery is charging. If the light is blue, either your battery is fully charged, or you don't have the pins lined up yet.When the light turns blue, your battery is charged, and the charger is no longer active. The pins slide easily, so you'll have to check them each time for alignment. Or tape the sliders in place.Using this with Samsung Note 3 batteries.

Exactly what is needed for anyone who still has a phone with a removable battery.Charging is not any faster than when in the phone itself, however, given that it's a standalone device, it isn't a big deal for me.It can be a bit annoying trying to fit the charger on certain outlets, as the prongs fold out from the device. In addition, plugging it into a standard wall outlet means your battery is hanging vertically, only held in by the clamp. It's unlikely to ever fall, but to get a good connection, you will likely have to fiddle with the battery and clamp while the charger is already plugged into the wall.Ideally, if they make a version 2, I'd like to see a little extension cord or something else similar to allow more choice as to where it can be plugged in, as well as to allow for easier battery connections.Finally, it whines when it's plugged into an outlet without a battery to charge. It's pretty high pitched, and surprisingly loud, but not enough to be very annoying, but you may feel differently.
