The worst part of Apple Watch ownership is packing the power cord when you travel. Not only is it a lot bulkier than a Lightning or microUSB cable, it’s also probably the only one you own, meaning you have to remember to take it out of your nightstand charging dock, and put it back when you get home. So annoying!

That’s what makes this battery pack so genius. At only 700mAh, it’s small enough to attach to your keychain, but big enough to charge your watch 1.5 times, which should get you through a weekend with ease. And for longer getaways, you can even plug in a microUSB cable (which you probably already have in your bag) and use it as a wired travel charger too, allowing you to keep your main charging cable at home. Just use promo code RHLDHVS5 at checkout to save $12.
