External Battery / 20V Power Bank for longer run time
« on: October 17, 2018, 03:43:46 AM »
Hi everyone!

Baptiste here from the ExperimentBoy French YouTube channel. As I do a lot of outdoor experiments filming that require long preparation times before the event -or the explosion- can happen, battery time is often an issue when I have to set up the camera and let it run for a while.

I've stumbled upon this Litionite power bank, it has a massive 50,000mAh capacity (185Wh), and can output both USB and DC Jack at 5V, 8.4V, 9V, 12V, 16V and 20V, which works perfectly for the Chronos and the amount of current the camera draws. (Also works great with an Atomos monitor at 12V) It comes with a ton of adapters.

It's a no-brand Chinese product, so you should be able to find branded copies everywhere. It cost me 150 (~USD 175)
Amazon FR/EU:
Amazon US (try searching related products):

I've run the camera only with the external supply (no battery in the camera, otherwise it draws much more current to charge it at the same time), and the power level dropped by 5% in 24 minutes. Pretty impressive...

Happy filming!
-- Baptiste

The external battery I bought is this one off of amazon:

It's handled things fairly well thus far, surviving being tossed around in my work bag and multiple coffee spills.. though it appears to have gone up in price by ~100CAD since I bought it..
