DSLR Power Bank for Outdoor Photography

[sakibnaz]

Hi All.

I want to buy a good quality Power Bank for my EOS 6D. I have very bad past experience of Power. I went to a Nepal Mountain Trip with high altitude and cold ... where all my Battery goes down also the AA Battery did not work.

So I am looking for a good quality Power bank with High Capacity (30A +) which can work well in High Altitude and Cold Environment as well.

I am planning to buy a USB Based Canon 6D Battery Charger so I can charge the DSLR Battery from the USB Port of Power Bank without need of an AC Inverted. Also I need 12V Out in Power Bank for my Motorized Dolly system.

Can anyone advise a good quality Power Bank?

Thank you in advance.

Regards.

I have used USB power pack for cell phones and tablets but I'm not sure about DSLR's

Which brand and model you used?

Thanks.

I am not a 6D user, but I believe it uses a 7.4 volt battery. USB is 5.5 volts. So USB alone cannot charge up a 7.4v battery without some other special circuitry (a step up or boost converter), which is less efficient than using a higher voltage, say 12v+, like a car charger would.

Since your other equipment requires 12v, and since 12v is very common, I'd go with that instead. There are tons of 12v options out there; from DIY to commercial battery packs. Depends on how much weight you wanna carry, and charging time (various lithium-based 12v options would charge faster and discharge deeper than lead acid, and be lighter, but are also more expensive).

Start here: http://www.powerstream.com. They make high grade stuff, and have some good info for someone without much experience in this area. They have either ready made stuff, or components if you wanna cobble something together yourself.

Hi.

Thanks for reply. Actually I found this below Charger which can charge Canon 6D LP-E6 battery from USB.

That's why I am looking for a good 5V Power Bank for my outdoor photography.

Regards.

No power bank will deliver 30+A but I think you mean you want a capacity of 30+Ah. RAVPower 26,800 mAh is the biggest I have come across. These types of power bank only deliver 5V through USB ports so if you want 12V you need to look at vehicle batteries. Either way you are going to have to step up/down voltages for your different needs.

There is no magic battery technology which will work well when it gets cold.

Hi.

Yes, I mean 30+ AH.

The RAVPower looks good and cost effective. I found the below one by XTPower ... it also have 12V Output.

Any idea how is that?

Thanks.

Hello

I think most power bank are 5V output. I don't know that if you could charge your camera directly in this way:

Also when you want to charge your battery, I do think the EasyAcc power bank can help you. Because it's ok for all 5V devices.

If you want, I can send you a sample to test it.

In case I don't get back to this thread and someone questions the math, etc.. (It's close enough.)
Here's the circuit and graph for the step-up design:

no idea (I use a cheap $10 Amazon power bank for cell phone)

but if it works for DSLR's let us know!

I had a feeling someone would call me out on that...just what I deserve for oversimplifying. And no excuse since I use a step-up myself.

And I kinda wonder why more of them (quality ones, not some of the cheapo junk out there) aren't available considering how ubiquitous USB is becoming as a power spec.

And I think I was wrong about the power of the camera battery too...

Thanks for the clarification.
