THINKWARE iVolt Mini Hardwired External Battery Pack Dash Cams, 20-Hour Parking Mode, 45-Min Recharge

I was looking for alternatives to hard wiring a dash cam to my car to record while parked, and to have a longer battery life. Although this is pricey, it has held up just fine especially in extreme Florida heat for a summer. After a year I still get over 8 hours of footage after parked, and usually only takes about 10-15 minutes to charge it all the way.

Excellent product

(5/5) – Great support, clear instructions, just hope the new unit holds up I installed the iVolt Mini in my 4Runner to support a dash cam setup, and the installation guide was excellent — very clear and easy to follow, especially for someone who prefers doing things right the first time. The included fuse tap instructions and detailed wiring diagrams made the process simple. Unfortunately, after about 8 months, the battery suddenly stopped powering on. I used Thinkware’s online troubleshooting and self-diagnostic guide, which was straightforward and very clear. It helped me isolate the issue — power was reaching the unit, but the battery pack itself had failed. I reached out to Thinkware customer support and they were fantastic. They responded quickly to every email, confirmed the issue, and sent me a prepaid return label to send back the defective unit. A replacement is already on the way. Overall, I’m very satisfied with the 10/10 customer service. I just hope the new battery lasts longer — but if it doesn’t, at least I know their support is solid

I wasn't planning on getting an ext. battery pack for my Viofo A229 Plus, but after some consideration and not wanting to put unnecessary drain on the battery in my GLC43, I bit the bullet and bought this battery. Everything you need to install this ext. battery is included with the exception of your hardwire kit for your specific dashcam. That said, the output wire is a good length and once you solder/connect your hardwire kit to the wires, you'll have more than enough length to snake this around your car. I decided to place my battery under the cargo space next to my spare tire as this kept it away from vehicle guests kicking the battery if I were to place it under the driver's seat. Overall, the ease of installation and included wires is a nice touch. This ext. battery does support my Viofo A229 Plus, you just have to be mindful of the wiring. Between the output wire and the hardwire kit, ACC is yellow on the Viofo HK4 while ACC is red on the Thinkware iVolt. Once you connect the proper wires together, parking mode works flawlessly. It's not the most robust battery when you compare it to others in the market, no app, limited in how many hours it can record. Where it does excel is its small footprint, if you want to tuck it away somewhere in your car.

Review: After getting hit and run, I needed a external battery for the dash cam. This one works great. Essentially plug and play. Comes with fusetaps to hardwire and after it is all set up, there are no issues. Parking mode works right away after hardwiring Pros: -Included Hardwiring supplies -LiFePo Battery for better wear resistance. Cons: -Price
