Rambo would be impressed.

Do you think that the guy who invented the carabiner would be impressed to see the state of his invention today?

Surely he imagined a bunch of crazy climbers using them to scale mountains, but he probably underestimated just how many would end up dangling from stroller handles or hanging from belt loops carrying keys.

Well 100 years later, we can do even better.

This is a carabiner that will not only carry your keys, but it’ll carry your next phone charge as well. Always have a backup charge when you need it, just by keeping your Mophie keychain with you.

In fact, we can send you two of them. And we’re not sending you two of them because we think that you’re so hopelessly addicted to digital devices that you need multiple eight-hour charges at your disposal. We’re sending you two of them so that you can keep one charging and one with you so that you’re always ready to go.

Get used to living life without charging worries with a backup battery always at hand and a charge-level indicator so you always know where you stand.

Maybe you aren’t climbing a mountain anytime soon, but you can be ready for a phone charging emergency wherever you go (mountains included, we suppose).

Free yourself from low battery anxiety and look at least a little bit cool doing it.

Otto Herzog would be proud. Oh he’s the carabiner guy, buy the way. Parting fun fact: his nickname was Rambo before Stallone was even born.
