The short version
How do you charge phones, cameras, and power banks on a Nepal trek? Guide to electricity on the trail — teahouse charging costs, power banks, solar, plug types, and keeping batteries alive in the cold.
- Carry a fully charged power bank (10,000–20,000mAh) — the single best way to stay powered without paying per charge.
- Teahouse charging works but costs more the higher you go (roughly $1–4 per device/hour) and can be slow or unavailable in bad weather.
- Cold drains batteries fast — keep them in an inside pocket by day and in your sleeping bag at night.
- Use airplane mode and a universal adapter; download offline maps before you go.
Power on the trail
Keeping your devices charged on a multi-day trek takes planning — electricity gets scarcer, costlier, and less reliable the higher you go. Here's how to keep your phone, camera, and power bank alive across a Himalayan trek.
Charging at teahouses
Most teahouses have electricity (grid, micro-hydro, or solar) and let you charge devices — but usually for a fee that rises with altitude, often charged per device or per hour (roughly $1–4). High up, where power comes from small solar setups, charging can be limited, slow, or unavailable in bad weather. Don't rely on it for critical power.
Bring a power bank
The single best solution: a good power bank (10,000–20,000mAh), fully charged before you start. It keeps your phone topped up for days without paying per charge, and means you're never caught with a dead device. For longer treks, a larger or second bank helps.
Solar options
For remote or camping treks with little teahouse power, a portable solar charger clipped to your pack can trickle-charge a power bank or phone during sunny days. Useful in dry, sunny regions (Mustang, Dolpo); less reliable in cloud.
The cold-battery problem
Cold drains batteries fast — a phone or camera battery can die surprisingly quickly at altitude. Keep batteries and power banks warm: carry them in an inside pocket close to your body during the day and inside your sleeping bag at night. A cold battery that seems 'dead' often revives once warmed.
Plug types
Nepal uses 230V and a mix of socket types (commonly Types C, D, and M). Bring a universal travel adapter. In cities you'll have reliable power; on the trail, sockets in dining rooms are shared, so be patient and considerate.
Smart power management
Keep your phone in airplane mode (GPS still works for offline maps) to dramatically extend battery life. Lower screen brightness, close apps, and only power up when needed. Download offline maps, books, and music before you go so you're not searching for signal. Carry spare camera batteries and keep them warm.
The bottom line
Bring a charged power bank (10,000mAh+) and a universal adapter, keep batteries warm against the cold, use airplane mode to conserve power, and treat teahouse charging as a paid top-up rather than your main source. Do that and your devices will last the whole trek — leaving you free to capture the Himalaya. See our trekking packing list for the full gear checklist, or contact us with any questions.
Frequently asked questions
How big a power bank do I need for a trek?
A 10,000–20,000mAh power bank, fully charged before you start, keeps a phone topped up for days. For longer treks or if you also charge a camera, bring a larger bank or a second one.
Why does my phone die so fast at altitude?
Cold temperatures drain batteries quickly. Keep your phone and spare batteries warm in an inside pocket or your sleeping bag, and use airplane mode to extend battery life dramatically.
