I'm going hiking in the Himalyas next month. I just purchased a new 760D body. The problem is, I cannot purchase spare batteries because they are not being sold in India. I can import them from the US, but it costs $250 to get it shipped here. I regret not purchasing a 70D body.

I won't have access to power source for atleast 10 days or so, and specs suggests this camera can only take about 440 shots. It will be even worse if I take long exposure Astro shots or shoot videos. I can't purchase DC Coupler and attached a external power source because even the DC coupler is not being sold here.

Can can I charge the batteries? I can carry USB power source.

  • Can a battery be charged whilst inside the body using a USB lead? My D80 allows this. – Paul Uszak Aug 14 '15 at 23:17
  • I think the basic problem here applies even if you had a handful of spare batteries. You'd want to be able to charge them, not hope that you had enough and that they retained charge for the duration of the trip. – mattdm Oct 22 '15 at 14:31

Perhaps a small power inverter and a solar panel would serve your needs. This would allow you to use your existing charger regardless of whether you have access to power or not

I finally figured out a way to charge my Canon 760's LP-E17 battery with 5v USB output and was able to go 15 days without power. I was able to charge my batteries 12 times using Xiaomi 16000mah power bank.

Here's how I did it.

  1. Purchased Neweer USB battery charger for Canon 1100D batteries. (Link: http://www.amazon.com/Neewer-Battery-Charger-LP-E10-Rechargeable/dp/B00ZHJ8XHQ)

  2. Opened the charger and hacked a piece of copper. Works as flawlessly as the original charger.
