EforTek 1000mAh Li-ion Battery (2-Pack) and Dual USB Charger Kit for SJ4000,SJ5000,SJ6000 and Geekpro,DBPOWER,Gookit,SJCAM

SJCAM and DBPowerHave been using these for a couple years with SJCAM SJ5000wifi, charge fairly fast, work great, no issues.Regarding my new DBPower N5 Pro, batteries are a tight fit along the thin outer edges, they will power the camera, BUT, removal is difficult, thought the pull tab would break before the battery came out. Doubt I'll try using them again with that camera. DBPower N6 has a completely different battery design and connectors, do not buy them for that model camera.

The unit will not charge two batteries at the same time with a common 0.5 amp power supply. The unit charges the batteries in serial (charges one battery to completion and then charges the other battery, thus potentially taking twice as long as it could. This unit does not come with a power supply.Note to manufacturer/seller: I think you would be well served to add the suggested power supply into this kit and adjust the price accordingly.One of the batteries heated up a little too much for my taste during one event when I was using the camera in the water proof case. That and the serial charging are the reason for the 3 stars rather than 5. Be careful with the battery getting hot. This can cause catastrophic failure which can result in bodily harm. My battery did not get that hot but be cautious.

Battery fits extremely tight in Geekpro camera. Once in, it powers the camera but you cannot remove it from the camera! The plastic tab completely broke off when I attempted to remove the battery. I had to carefully wedge it out with a flat blade. Totally defeats the purpose. This is going back today.

I was wondering what will happen to my little GoPro knock off camera after the included batteries go bad, so I was on a hunt for a replacement. I came across this one and the Wasabi one. Both come with two batteries and a dual charger.The set is small and convenient and the batteries are charged relatively quickly. However, they don't last much longer than the ones that came with the camera even though they have higher 1000mAh. They last about 30min of continuous shooting. Overall, I am happy to have this set with me for some extra action time.I paid for full place and my reviews are unbiased on how much I paid for the item.

These fit might gookit camera just right and I charged them. Both charge at the same time and both turned green at the same time. I put both in the camera and they showed a full battery on the camera screen. Very handy to have a double charger and two more batteries. I would recommend this.

Well I bought this for my GEEKPRO EOV1 4K HD. The batteries will not fit the camera, they are to big to fit into the camera. The battery on the Geekpro is rounded on one edge. A total disappointment ! The charger seems to work with no issue. The chart showed that these batteries are supposed to fit the Geekpro. I would be sending this back, but I don't know what happened to the box. Buyer beware.

I purchased this for my GoPro knockoff. I only get about an hour of use before the battery is dead. If I charge the batteries fully and take them off the charger. I go to use them in the morning and they are dead.The charger worked for the battery that came with the knockoff GoPro. That is why I gave it an extra star.

They are cheap but good for sparing.
