Will Electric Cooler Drain Car Battery

I used this product because it is less drain on my camera battery

Love it so much, did not experience any noticeable battery drain while sitting.

I have a small hatch back and was looking for a mobile power station to use with my electric cooler. The space in my trunk is very constrained and simply put, this knocks it out of the park. This unit easily runs my cooler for 24 hours, even in my confined trunk with minimal airflow. I have also been using it as a portable power station to run my Laptop, charge USB devices, etc. with zero difficulties. It really is as simple as plug in and go. The light weight is also a massive bonus and makes loading the car very simple!

The drain battery feature is brilliant. It helps maximize the life of your batteries.

This is exactly what I needed. I still haven't managed to drain 1 full battery on a busy shoot.

I like the separate meters for each battery and drain option to get the batteries back to full charge.

You can never have enough juice. You're constantly reviewing off the LCD can drain the battery charge so having a spare is a must.

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

I enclose my electric car key in the Keymaster and loop it to the inside of my wetsuit when I surf. The 'pac has endured some good use and remains dry on the inside with light submersion in water. It's seal is of two, heavy-duty, interlocking plastic pieces and the bag is of very thin yet durable plastic. It does fit an iPhone 4 without a case.

recommend spare back up battery for cold weather battery drain & about the time you want a shot---the battery is dead.
