Egen Cellink NEO 5 Dash Cam Battery Pack by EGEN with Smart LifePO4 Technology for Extended Parking Mode Operation and Recording Time, Black

Charges really well when hardwired so it has enough to run my omni 4k surveillance dashcam all night

I purchased this battery after reading lots of reviews on this and the BlackVue models. Turns out they are made by the same company. Fitted under the passenger seat in my Porsche with a 2 cam BlackVue system and it's great. lasts for at least 4 days on parking mode. charges is 45 to 50 mins while driving. easy to fit. worth the money compared to the branded over pirced, less powerful ones!

Used for my car dashcam plus it provides power to my dash camera when car is parked, it lasts about 20 odd hours while parked and filming any motion, would be great if it lasted double that time and also if it had a power charge lead to be able to charge it from home, bought it about 2 months I think and I am still happy with it.

After using it for four months via cigarette connector cable to charge Cellink NEO 8+ Dash Cam Battery Pack, the cigarette connector was too hot and melted. Eventually, when I opened the cigarette connector, I realised that there are a spring and a 10A fuse. The contact of the spring was too hot due to too thin having too high current passing through it when charging.Finally, I soldered a short 13A electrical cable to the two end of the spring and reinstalled it to the cigarette connector cable to solve this problem. With this short electrical attached in parallel with the spring to branch the high current, now the cigarette connector charging cable working perfectly without getting hot again and the Cellink NEO 8+ Dash Cam Battery working good.

Had the Neo 6 now since Jan 2021 and it’s still going strong after nearly daily use. Can’t fault it at all, very reliable.

Firstly, the good:- Fantastic build quality, it really feels solid and well made.- Well packaged- App is a great addition, it shows you the current battery levels and input/output, with an estimate on time left on the batteryHere's the flaw.TLDR (Explained in detail below) -> If the battery completely runs out of power, it won't start the dashcam as soon as your engine turns on, which results in missing footage.If your dash cam uses too much power in sleep mode, or you don't drive very far - this just doesn't work.I drive my car 5mins up the road in the morning to walk the dogs out in the fields. 10mins up the road to the supermarket once a week and a 45min round trip to drop my wife at work twice a week. The dashcam is correctly turning into parking mode when stopped, and only recording when motion is detected, which is the lowest power usage that's actually useful to use. (G-sensor recording misses the impact, or if the car is keyed, might not even trigger)I've not driven far enough to keep charging the battery up long enough for it to survive through the night. It gets to around 3/4am, and then runs out of power. That's not a big problem in itself, as I don't need it running when my car is parked on the drive, as I have CCTV in the house.The real problem is when I go to start the car in the morning to drive to walk the dogs - when the battery is dead and you start the car - it doesn't immediately pass through power to the dashcam, it takes anywhere between 3-10mins to turn the dashcam on. I can only assume the battery is charging itself before it decides to pass power through to the dashcam. I didn't notice this until the 3rd time, when I pulled the footage to check the parking mode footage, to find most of my real journeys weren't covered at all because the battery was still charging and hadn't turned the dashcam on.This is a fundamental flaw in the design which makes this useless for my use case.

Same as before come as quick as possible, Very happy with this

Bought this to use in my driving school car as i wanted a battery back up for the dash cam without draing my car battery.great compact size and powers my blackvue dr900s 2ch camera for a good 18+ hours when parked.much cheaper than the blackvue version.
