Ravpower Portable External Battery Charger

I was looking for a charger that I can use to charge via a USB-C port, to take advantage of fast charging using a battery pack while traveling. The Jupio charged a single battery from just 3% charge left, all the way up to 100%, in 2 hours and 38 minutes. After 2 hours the battery was up to 93%, so it took the remaining 38 minutes to charge the extra 7%. I also have a RavPower charger (no longer available) that uses a micro-USB port for the charger. The micro-USB specification limits the amount of current traveling from the battery to the charger, so it's not as fast. A similarly depleted battery took 3 hours and 20 minutes to charge in the RavPower. When buying such chargers, pay attention to the current supplied to the battery. I couldn't find many chargers that can supply 8.4V at 1A to a battery as the Jupio does. For example the RavPower is rated at 8.4V and 0.7A, so it charges much slower. The other notable charger that seems to handle 1A is the SmallRig one, but it was not available when I got the Jupio. Note that charging 2 batteries at the same time will limit the amount of current going to each battery to 0.8A, which means slower charging overall. I have not tried to see how long it takes to charge 2 batteries.

easily portable battery charger

Needed to connect RAVPower USB battery to MixPre 6. Works great.

Using a RavPower 28600 mAh battery pack I've been able to power my GH5 camera recording 4K 10-bit video for 12.5 hours. My GH5 got fairly warm, but everything worked flawlessly. I may use this system to power the new Blackmagic Pocket Cine Camera 4K by adding a $35 Canon LP-E6 battery adapter to my kit.

Great extra battery and an external charger. Perfect for going on long trips when you need more battery life.

Quality inexpensive battery charger. Ideal in that it is better to charge the batteries in an external charger vs. thru the camera.

Running off a laptop means it helps to have an external that has its own power source so its not draining my laptop battery. I have a portable drive so I use this one when in the studio and both always contain the exact same files. I have used Western Digital for years and trust them as I have never had one fail.

This is a great little portable battery charger. I carry it in my camera bag. It gets t he job done quickly.

If you shoot much at all, must have the external charger

The battery works fine. It does take some time to fully charge the battery using the external charger, but I like the higher capacity of the battery. Also, the price came down which make it even better.
