I’m taking a Canon EOS 760D on a long trek where I may have no mains power for 10 days or more. The camera uses the LP-E17 battery, and spare batteries or Canon power accessories are difficult to get locally. I can carry a USB power bank, but I need a practical way to recharge the battery in the field. What are my options for charging an LP-E17 battery while hiking?

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

A practical field solution is to recharge the LP-E17 from a USB power bank using a compatible external charger. One community member reported successfully charging a 760D battery multiple times from a high-capacity USB power bank and lasting about 15 days without mains power.
Another option is to carry a small inverter with a solar panel so you can use your normal wall charger away from outlets, though this is bulkier and less efficient than direct USB charging.
For hiking, the simplest approach is usually:
- a USB power bank
- a charger that can charge LP-E17 batteries from USB power
- one or more batteries if available
Be cautious about modifying chargers or using improvised metal contacts: it can work, but it also carries safety and battery-damage risk. A purpose-built USB charger for the LP-E17 is the safer choice if you can find one.
To extend runtime, minimize video, Live View, image review, and unnecessary screen use, and keep batteries warm in cold mountain conditions.
