Charging your Apple Watch without a wall outlet: tricks and alternatives
Low battery icon on your Apple Watch. No charger handy. We've all been there. You're on the go, far from the nearest outlet, and your smartwatch gives up the ghost. The solution is usually in your bag: extra cables, power banks, the whole arsenal of accessories . But what if your iPhone could save the day? Sounds like a fairy tale, right?
Apple never officially said it's possible. There's no built-in feature for it. However, with the right tricks and a bit of creativity, you can power your Apple Watch with your iPhone's battery. No magic required, just clever use of what you already have. Just like you share AirPods with your iPhone, you can also breathe life into your watch. In this article, we'll explain how to keep your Apple Watch running even when you're not connected to a power outlet.

The reality: direct charging does not (yet) exist
Let's be clear: you can't currently charge your Apple Watch directly from your iPhone. Apple hasn't (yet) built this feature into its devices. The watch needs its own magnetic charging ply that draws power via USB. However, this doesn't mean your iPhone is completely useless when your smartwatch runs out of juice. There are clever solutions that can indirectly use your phone's battery to revive your watch.
Reverse wireless charging: the future?
Several Android smartphones already offer reverse wireless charging. This allows you to charge other devices by placing them on the back of your phone. Samsung, Huawei, and OnePlus have had this technology in their top models for years. For iPhone users, it remains a pipe dream for now.
Rumors have been circulating for years that Apple is working on similar technology. Patents have been filed, and prototypes are reportedly being tested internally. Future iPhone models are expected to feature this feature. Until then, we'll have to make do with alternative solutions.
Practical solutions with existing technology
Wireless power bank with MagSafe
A wireless power bank that can charge both your iPhone and Apple Watch is currently the best option. These accessories usually have a MagSafe charging surface for your phone and a separate magnetic charging ply for the watch. You charge the power bank first, after which it can power both devices without an outlet.
These power banks range in capacity from 5,000 to 20,000 mAh. A 10,000 mAh model can fully charge your iPhone about twice and your Apple Watch more than ten times. Perfect for weekend getaways or long workdays.
Lightning to USB adapter
With a Lightning to USB adapter (also called an OTG adapter), you can theoretically connect your Apple Watch's charging cable to your iPhone. However, this method doesn't work natively. iOS blocks power transfer to external devices to protect the battery. Only a jailbreak is a way to bypass this restriction, but we strongly advise against it due to security risks.
Battery cases with extra functionality
Some iPhone battery cases have a built-in Apple Watch charger. These cases do make your phone thicker and heavier, but they provide extra power for both devices while on the go. The case charges your iPhone first, then you can charge your watch via a fold-out magnetic puck.
Optimize energy management
Instead of searching for ways to charge, you can extend the battery life of both devices. For your Apple Watch, this means:
- Turn off the always-on display
- Reduce the number of notifications
- Use power saving mode during workouts
- Turn off Wi-Fi and mobile data when not needed
- Decrease the screen brightness
Similar tips apply to your iPhone. You can also activate low-power mode when the battery drops below 20%. This will extend your battery life by a few hours.
Accessories that make a difference
Good preparation prevents problems on the road. These accessories are essential for those who regularly find themselves without a power outlet:
Portable charger for Apple Watch
A compact charger specifically designed for your watch fits in any pocket. These mini power banks often have a capacity of 1,000 to 2,000 mAh. Enough for three to five full charges of your smartwatch. Some models come with a keychain, so you can always have them with you.
Multi-device charging station
A charging station is ideal for your home or office. You can place your iPhone, Apple Watch, and AirPods on the station simultaneously. A single cable to the wall socket is all it takes. All your devices charge overnight, so you can start the morning with full batteries.
Solar power bank
Power banks with solar panels are an attractive option for outdoor enthusiasts. These charge using sunlight. While solar charging speeds are limited, you can still generate extra energy during hikes or bike rides. This is especially useful for multi-day trips without access to electricity.
Future developments
Apple is constantly working on new technologies. Besides reverse wireless charging, the company is also researching other innovations, such as more efficient, longer-lasting batteries and faster charging technology. The latest Apple Watch models already charge faster than older versions.
Device integration is also improving. There might be a feature where devices automatically share energy when one is low. Or a system where you can set priorities: charge the iPhone first, then the watch.
Conclusion and practical tips
While you can't currently charge your Apple Watch directly from your iPhone, there are plenty of alternatives. A wireless power bank with dual charging is the most practical solution. Combine this with smart power management, and you'll rarely run out of power.
Looking ahead, we'll have to wait and see when Apple introduces reverse wireless charging. Until then, the right accessories can make the difference between a dead battery and being able to keep working. So invest in a good power bank or portable charger. Your future self will thank you the next time you're far from the nearest outlet.
Conclusion: smart alternatives until Apple offers the solution
Charging your Apple Watch directly from your iPhone remains a dream for now. Until Apple introduces reverse wireless charging , you'll have to rely on smart alternatives. A compact power bank with dual charging functionality or a portable Apple Watch charger will solve the problem on the go.
Combine this with conscious energy management—fewer notifications, lower screen brightness—and you'll go a long way. The right preparation will save you frustration the next time you're without a power outlet.
