It clips onto keys or a bag like an ordinary carabiner, but it hides a short charging cable and has a bottle opener built into it, which covers two of life's more frequent small emergencies.
The cable is the part people don't expect. It's short by design so it doesn't tangle, and it's there in a café, a car or an airport when the phone is at four percent.
It's compact enough that it doesn't turn a keyring into a brick, which is the single reason most multi-gadget keychains get taken off again within a fortnight.
The carabiner clip means it also goes onto a backpack, a belt loop or a gym bag depending on what someone carries, rather than being locked to keys.
Having the bottle opener on your keys is quietly brilliant at barbecues, camping trips and festivals, where there's always one opener and it's always with someone else.
It suits tradies, travellers, festival-goers and anyone who likes a practical gadget with a bit of attitude, which is a broad group and an easy one to buy for.
You're giving something that gets a genuine reaction on opening and then stays in daily use, which is the ideal outcome for a gift at this price.
Check which connector their phone takes before you buy. A charging keychain with the wrong end on it is just a carabiner with a bottle opener, which rather halves the point of it.
