ADIKA Hero 4 Dual Charger + Battery Eliminator USB Car Charger for GoPro + 2 pcs for Go Pro Hero4 Rechargeable Batteries Pac AHDBT-401 Accessories Bundle for GoPro Camera Back up Batteries

This charger and battery set work well. The batteries do not outlast the go pro battery but they are pretty close. The charger does its job and pretty quickly. Good product for,the money.

Works correctly and the car dual charger is wonderful.

doesn't work with one of my eken action cameras

This is a great battery pac, I use my gopro with my drone and I do not have to be worry about my gopro battery level, I land my drone and just change the battery on my camera. This also gives me more flying time since my drone is not charging the camera.

Works the way it should.

This was a Christmas present for someone else so I'm not really able to give you an opinion on the quality of the charger and batteries.

If you are an adrenaline seeker like me, the last thing you want is to have your c go dead in the middle of an amazing jump! Plus- having to fumble with charging in your pocket risks water damage... I love that I can just switch the battery and keep pushing my winter (and summer scuba hobbies to the max!)

Work good !
