Replacement 3.7V 3500mAh Battery Pack + US / EU Plug Power Adapter for Samsung Galaxy Note 2 N7100

Pros: The quality of construction for both the charger and battery is surprisingly quite good. Charger also offers a spare USB port with 5V supply to charge another device. Battery doesn't get heat up much while charging. I was quite conscious about the safety aspects as this is a Li-ion cell, so was monitoring if the battery gets heated up. LED shows different colors to indicate the different status: "charging", "charge completed", "USB port in use".

Cons: Charges the standalone battery quite slowly, estimated at about 300mAH, but this probably explains why it doesn't heat up the battery too much when charging.

Other: Good value for money. Great as a standby for peace of mind in case my original phone battery runs down and I have nowhere to charge.

Pros: You can load an extra battery while you use your phone! Fit and quality is fine. The one I have is a little bit different to the current picture. The battery is turned 90 degrees and kept in place in the other direction. I don't know how this is with the current one. A replacement battery for great money.

Cons: Loads terribly slow. SLOWWWWW. Many times it doesn't load the spare battery over night (6-7 hours sleep) which I think is bad. Ok 95% of the time it doesn't matter as I most of the time put it in the loader just after dinner time. The replacement battery is 400 mAh more than the original, but in use it discharges 25% faster.

Other: An ok replacement battery and the ability to load the spare battery. Only the capacity of the battery is ok not great, less than the original. The loading process is SLOOOWW

Pros: Cheap, usefull, extra battery and charger small, You can charge the phone and the battery at the same time because of the usb connection.

Cons: none found. It's a charger with an extra battery.

Other: Cheap extra battery in case you're original battery is empty when you are outside and can not charge the original battery. Then this is a very good battery because it take just a litte room in your purse, coat, jeans
