12V Battery For Remote Car Starter

I purchased this to scavenge the fake battery with the DC cord (the part of this Watson kit that plugs into the camera's battery bay), in order to create a 12V battery eliminator, which I use for astrophotography from remote sites that do not have AC power available. It worked perfectly! I combined the fake battery part with a separate 12V DC to 8V DC converter (actually a variable output DC to DC converter set to 8V output) that I already had in order to power the camera from a 12V source, such as a vehicle battery, automobile power outlet, or a 12V portable solar power system. This allows shooting all night long in remote locations without worrying about either having enough camera batteries or having to switch out batteries during hours-long photo runs. It also eliminates the heat of the discharging battery from inside the camera body, thereby allowing the camera to run cooler and reducing sensor noise (dark current) I tested the AC adapter and it also worked perfectly. Excellent performance, low price, well made. I recommend this item.

All I can say is wow, this tiny lithium jump starter got what thought was a dead as a doornail car battery back to life

A very cost effective, multi-featured charger. The 12V. car cord and USB power output jack are handy, included extras.

I bought this, and was delighted that it came with a 12V connection for the car/Jackery as well as a 240V adaptor. Can't beat that for $20.

works great as wall plug and 12v car charger for Watson and Sony batteries and has USB port to charge any additional device

It charges a battery using your car. Not much else to say.

Needed a 12v power supply for a remote PTZ camera controller. This power supply has worked out great so far.

I really love my tiles because I’m always looking for my remote or my car keys.

Other than a jack, this compact jump starter is the number one item every car should have in it. Completely discharged my battery overnight, hot the"boost" and the car turned over immediately.

Perfect for the right occasions!!! Let's first talk about the mounting option accessories that ship with it so you can configure it to mount to cameras, providing various solutions. That's sooo smart. The build... DTap and other sources are well placed and can be used for multitudes of equipment. Crazy. The battery lasts a. Long. Long. Time!! I used it for more than it's "intended" purpose on a music video shoot. I rigged a 7" 12v monitor (DTap), powered a follow focus knob (5V), a wireless HD video receiver (12v), and .... something else. Effortless. The team loved the rig!!... you could see the gears in their minds spinning with possibilities !!!!!! Think outside of the box with this unit. Each item also had a battery attached for backup power IN CASE the handle dropped out at anytime. At that point, it could still be a handle. It lasted the ENTIRE duration of my needs... easy 6 hours without depleting. It's chunky even in a large hand, so be mindful of fatigue if rigged onto a heavy system. I first used it on a caged BMD 6K and it flowed easily for 3.5 hours. It powered the camera, and a 7" monitor for what I recall to be the entire live event (intermittent use, but powered up 85% of the time) Have a great time with the unit!!! I got mine on Daily Deal for about 25% off. I'm a fan!!!
