Music all day: a power bank charging case that keeps the earbuds ready to go
- Earbuds running out of battery away from a charger
- Not knowing how much charge is left
- Juggling music and calls across two devices
- Needing a separate power bank for phone and earbuds
Music all day, without the battery panic
Stop watching your earbuds die mid-song. This charging case carries its own power, so the music lasts from the train to the gym.
One case, two jobs: buds and power bank

Your phone gets charged too
The 1500mAh case doubles as a power bank for your phone. The earbuds stay topped up from the same case, so one charger in the bag covers both.

Know exactly how much is left
A digital display on the case shows the battery percentage. Glance at it before the commute or the run and you know where you stand, no guessing.

Two devices, one pair
Separate the earbuds and each one connects to a different device. Music can play on your phone while a call comes through on your laptop. Put them back in the case to pair again.

Charges the case
Dead buds on the platform, fixed in one case

The playlist dies on the platform
The train pulls in, the chorus hits, and the left bud cuts out. A basic case is a plastic box with no way to charge anything when you are stuck away from an outlet.

The case that charges the buds
The AKZ-S18 case is a 1500mAh power bank. Drop the buds in and they top up while you are out. The LED percentage tells you exactly what is left before you leave the house.

Music all day, no charger needed
A full day of listening, calls on the way home, and your phone topped up from the same case when the battery dips. No second power bank in the bag and no charger left on the desk.

Questions and answers
For a single session, yes. Each earbud runs about 5 hours on a charge. The case holds 1500mAh, so you can top the buds up between a train ride and a run without finding an outlet.
The shell is glossy plastic, so it shows fingerprints and light marks sooner than a matte finish. Keep it in a pocket or bag with the lid closed and it stays clean.
The case power covers the earbuds first, then leaves room for a phone top-up. Expect a partial charge, not a full one. For a full phone charge on a long day, keep your usual charger handy.
Yes. Separated, the earbuds connect to two devices at once, so music can play on one while calls come through on the other. Each earbud has touch controls for playback, skipping tracks and calls.
The LED display on the case shows the battery level as a percentage. Check it before you leave and you know whether the buds need a top-up on the way.
A separate power bank is one more thing to carry and charge. This case handles the earbuds and gives your phone a top-up, so you carry one charger instead of two.
