How to Charge a Smartwatch While Traveling or Camping

Know your watch's charging setup

Smartwatches charge in two main ways: a magnetic puck that attaches to the back, or a cable that plugs into a proprietary port. Apple Watch models rely on a magnetic charger, while many Android-compatible watches use a small dock with pogo pins. Some newer models have a standard USB-C port on the watch itself, which simplifies travel because you can use any USB-C cable.

Check the manufacturer's spec sheet or the included accessories to confirm the correct charger. If you lose the original cable, you can buy a replacement that matches the connector. For travel, pack a short cable and a small dock that keeps the watch stable on a table or nightstand. You might also want a compact carrying case so the charger doesn't get tangled in your bag.

Choose a power bank that works for your watch

A power bank is the most reliable way to charge your watch when outlets are scarce. You don't need a huge battery bank; watch batteries are much smaller than phone batteries. Focus on finding a bank that has the right output port and a reliable cable. Most power banks have a USB-A port, which works with almost any watch charging cable. Some have a USB-C port that can also power the cable if you use the right adapter.

If you plan to charge multiple devices, a power bank with two output ports lets you top up your phone and watch at the same time. Look for one with a capacity that suits your trip length, but remember that weight matters if you're backpacking. A compact bank that fits in a pocket is often easier to use than a larger brick. For a rugged trip, consider a rugged GPS watch that pairs well with a small power bank.

Pack the right cables and adapters

For travel, the ideal cable is short, durable, and has the correct connector for your watch. A coiled cable can be convenient, but avoid cables with sharp bends near the connector. If your watch uses a detachable magnetic puck, you can replace the cable with a longer one if needed. Carry one wall adapter that has multiple USB ports so you can charge the watch and phone overnight.

Some watches support wireless charging, but the charging coil is often positioned differently than on a phone. A standard Qi pad may not align properly with the watch's coil, so a direct cable connection is more dependable. If your watch has a proprietary dock, bring the dock rather than experimenting with a third-party charger on the road.

Plan your watch's battery for the trip

Your watch's battery life can vary drastically depending on which features you use. GPS, cellular, an always-on display, and frequent heart-rate checks are the biggest drains. Before you leave, go into the settings and enable a battery-saver mode if your watch has one. This usually reduces screen brightness, disables the always-on display, and extends the interval for background health measurements. Learn more about battery modes with GPS on.

Many watch operating systems let you customize power budgets. On Wear OS, you can turn off tilt-to-wake and reduce the timeout. On Apple's watchOS, you can enable Low Power Mode to temporarily reduce background activity. For Garmin watches, you can switch between different battery profiles, such as Expedition mode, which records GPS points less frequently to stretch the battery for days. For more on battery management, see battery-saving features.

• Turn off the always-on display and use raise-to-wake instead.
• Reduce screen brightness and shorten the screen timeout.
• Disable LTE when you don't need it.
• Use a simple watch face with fewer complications.
• Limit notifications to only important apps.
• Set GPS recording interval to every few minutes instead of every second.

Charging strategies while traveling

Charge your watch whenever you have a few minutes, not just when it's nearly empty. In a car, plug a USB charger into the vehicle's port. In a hotel, use the wall adapter by the bed. When you're out hiking, keep a small power bank in your backpack and top up the watch during a lunch break. This keeps the battery above a comfortable level and reduces the risk of running out during a long day.

If you're camping without power, try charging your watch during the day while you have sunlight. A solar panel can charge a power bank, and later you can use that stored energy for the watch. Direct solar charging of a smartwatch is still rare, so plan on using a power bank as the middle step. For multi-day trips, a power bank with a higher capacity will give you more overnight top-ups. Learn about solar charging if you're considering a watch with that feature.

Choose a watch that fits your travel needs

Your watch's battery capacity and charging method matter more for travel than for daily use. If you plan to spend nights in a tent, look for a watch that can last multiple days on a single charge with GPS on. Outdoor-focused watches from Garmin, for example, are known for extended battery life and can go several days between charges. Explore our best Garmin smartwatches for models with long endurance. Apple Watches and Wear OS watches generally require daily charging, though they charge quickly.

Consider how you'll charge the watch. A watch that uses a standard USB-C cable is easier to keep charged with the same cable you use for other devices. A proprietary magnetic charger is still fine, but you'll need to carry that specific cable. If you want to go longer without charging, some Garmin models offer solar charging, which can extend the interval between charges without adding much weight.

What to pick for your use

Questions

Can I charge my smartwatch with my phone's charger?

Yes, as long as you have the correct cable. Most smartwatch charging cables end in a USB connector, so you can plug them into any USB power source, including a phone charger or a power bank. For faster top-ups, consider looking at fast charging features.

Do I need a special power bank for a smartwatch?

No, a standard power bank with a USB port is enough. The key is having the right cable that connects from the power bank to your watch's charging puck or dock. Just make sure the power bank has enough capacity to cover your trip.

How long does a power bank last for a smartwatch?

That depends on the watch's battery size and the power bank's capacity. A typical power bank that charges a phone once can often charge a smartwatch multiple times because watch batteries are much smaller. See our smartwatch battery mAh guide for more details.

Can I charge my watch from a solar panel?

Indirectly, yes. A solar panel can charge a power bank during the day, and then the power bank can charge your watch. Direct solar charging for watches is rare and only available on select Garmin models. Check out our solar charging explainer for more.

Should I turn off GPS when I'm not using it?

Yes, GPS is one of the biggest battery drains. Only enable it when you need to record a track or navigate. Turn it off after your activity to save power. You can also use a GPS battery mode to extend usage.
