I like to use a second battery and external charger so I'm never waiting for a charge.

First one broke in two days. Company sent me a new one. It works fine. The fact that it is universal in design makes it a little tricky. There are small moveable pins that you align with battery contacts per included instructions. They tend to move. A shot of hot glue may be in order if being used for only one battery type.
The battery lasts as long as the phones original battery.

These are designed for 2 batteries in series.  If you only need one battery,  simply install 2 with the top one upside down.  Now you have a spare handy.

So nice to be able to change multiple batteries at once.  Never without Go Pro battery power now.

I have use this seveal times already, and now I have 5 tools that run off this same battery.  Nice to have tools that you only need one type of batter to run.

Nice to be able to open two different doors (even different manufacturers), but doesn't last long until it needs a new battery. This wouldn't matter so much if it used AAAs, but it's a flat, watch-style battery.

I love that you can charge each battery individually instead of in pairs. Each "channel" has it's own display readout to let you know each battery's charging progress, which is super helpful. It is a trickle charger so charging times are longer, but that's supposed to help with battery longevity. I'm happy with this product so far.

It's great to have a spare battery and it was a lot cheaper than buying it from Battery's plus bulbs !!

I spend a lot of time out and about, it's great to be able to carry a fully-charged spare, and pop it in when the battery you were rocking gets used up. These work great in my Samsung Galaxy S

I bought two of them so I can charge one while using the other battery! I can now check for battery charge longevity in my CoolPix885 camera! Thanks!

I always like to have three batteries for my digital cameras, one in the camera and two fully charged ready to go.  This fall we left the camera case with the charger and the two extra cameras at a sports field and it did not show up again.

I looked at buying the original battery from Panasonic or these OEM batteries and charger.

In the past I have for the most part had good luck with OEM batteries, but not always, once I bought batteries that physically were a little bit bigger and got stuck in the camera, once I got a battery that simply wouldn't hold the charge.

In this case I must say I am very pleased.  Not only did two batteries AND the charger cost less than only one single Panasonic original battery without a charger.  These two batteries hold the charge longer than the one original Panasonic battery I have left.

The charger is the nowadays typical smart model with the 110V prongs foldable so they both take up less space and will not break as easily when in the camera case.  It also came with a 12V cable that comes in very handy when you have forgot to charge the extra batteries at home and instead you can give at least one of them a bit of a charge in the car to wherever you are going.

All in all - an incredibly good value - I would recommend these batteries and charger to anyone wanting some extra batteries to be sure to not miss the action.

Gave me more than enough battery. Can charge two things at once to 100% with a little to spare. Awesome

It's nice to have a couple spare batteries around. These are a good price. They're a good quality product. They work in the note 4.

Bought this to replace worn out gopro battery.  Good price and nice to be able to charge two batteries at the same time.

Nice to be able to buy additional connectors without having to buy a whole new unit.  I use these on all of my battery started "toys".

Very happy to be able to charge 2 items at once. Works well.
