Our take on the Keychain Power Bank

This is a tiny emergency power bank that clips to your keys and plugs straight into a phone, built around a roughly 1500mAh cell. That capacity is enough for a partial top-up, not a full recharge, so it suits people who want a safety net for a dead battery rather than a day of heavy use. Against standard 5000mAh to 10000mAh pocket banks it is far smaller and lighter but delivers a fraction of the charge, and it skips cables entirely. Treat it as a backup for one call, a ride request or a ticket, not as your main power source.

Questions and answers

How much charge does a 1500mAh keychain bank add?
Expect a partial top-up, not a full recharge. On most phones it covers an emergency call or a short stretch of use before you reach a real outlet.
Do I need a cable to use it?
No. The bank plugs directly into the phone, which is the main reason it stays useful on a keyring.
Can it charge a tablet?
Only marginally. The cell is sized for phones and quick saves, so a tablet will draw it down almost immediately.
Is it worth carrying over a normal power bank?
If you want something you never forget and only need emergency power, yes. If you need a full recharge or two, a 5000mAh or larger bank is the better fit.
Will it fit my phone case?
A thick case or a case with a raised lip around the port can block the plug. Thin cases usually work fine.
What is in the box?
The keychain power bank itself. There is no cable to pack because the connector is built in.
Where is the Keychain Power Bank cheapest?
At Tecnoant, for $29.99, as of our latest check.
