Keychain Apple Watch charger is great for emergencies

I have an Apple Watch keychain charger and it's one of the most useful accessories I own, especially when traveling.

I use the keychain charger to charge my Apple Watch at night, then toss it in my pocket or backpack if I think the watch might need a top-up during the day.

It's great when there's no easy access to outlet power, like touring a foreign city or when camping.

Apple Watch keychain chargers are quick to recharge, easy to carry, and very handy in lots of situations.

We have a well-reviewed keychain charger on sale for just $18.99 (regularly $49). And it doesn't even have any cables!

Apple Watches seem to get better every year; their only limit appears to be their batteries. If you’re not willing to shell out $799 to get the new Apple Watch Ultra, which boasts up to 60 hours of battery life, you can still get enough juice for multi-day excursions with this Apple Watch-compatible wireless keychain.

This very portable Apple Watch charger is on sale now for just $18.99 (regularly $49).

An Apple Watch charger, anywhere you need it

This keychain-style charger is compatible with all models of Apple Watch. Measuring just 2.5 inches by 3 inches by 0.5 inches, this Apple Watch charger is ready to go anywhere. Just attach it to your keyring, connect it to a zipper pull, or clip it on a carabiner to keep it handy.

Its matte finish will easily blend in with your other gear. And its strong magnetic connection will securely hold your Apple Watch while allowing you to rotate it freely.

Four LEDs on the front indicate the charger’s status. Plus, it protects your smartwatch from overheating, current spikes, excessive voltage and short circuits.

The keychain packs a 950mAh battery and offers pass-through charging. This means you can set it up on a nightstand or desk to charge your Apple Watch as you juice up the charger itself. (The charger comes with a micro USB port.)

Once you’re set, clip the charger back on your keyring and resume your adventure.
