Mini Power Bank 2000mAh with USB-C Direct Plug, Keychain Format and Water-Resistant Casing for Smartphone

Battery at 4% – on the train, no outlet, and that important call is still pending

It's 5:20 PM, the train is overcrowded, the next free power outlet is out of reach, and the smartphone shows 4% battery remaining – while the train app displays the next platform, ticket, and connection. A classic power bank is large, heavy, and sits at home on the desk because it never fit in a pocket. The charging cable isn't even with you. This mini power bank, in a keychain format with a fold-out USB-C connector, fits on a keyring, in a pocket, or in the smallest purse compartment – and plugs directly into the smartphone without a separate cable.

What makes this mini power bank different

• Fold-out USB-C direct connector without separate cable – the integrated connector folds out and plugs directly into the smartphone's charging port; the constantly forgotten or misplaced charging cable becomes obsolete, and the power bank is immediately ready for use as soon as it comes out of your pocket.
• 2000 mAh battery capacity for emergency charging – the capacity is sufficient to bring a smartphone from a critical battery level to a safe reserve, ensuring that calls, navigation, train tickets, and payment functions do not fail on the go; the reserve is designed to bridge the gap until the next power outlet.
• Keychain format for constant availability – the compact, lightweight design can be hung on a keyring or carried in a pocket without being perceived as additional baggage; unlike bulky power banks, it genuinely stays with you instead of lying at home.
• Water-repellent and dust-protected casing – the robust casing withstands raindrops, splashes, and the jostling in pockets without moisture or dust affecting the electronics; this makes the power bank a reliable companion even in changeable weather.
• Compatible with Android and current iPhone models – the USB-C variant directly charges Android smartphones, tablets, and iPhones from the 15 series upwards; depending on the model variant, a Lightning version is also available for older iPhones, ensuring the right device is served.
• Lightweight for everyday use – the small size and low weight make the power bank a constant companion that neither weighs down the keyring nor bulges out the pocket; it is small enough to be carried permanently instead of just packed for planned trips.

Who it's for

For commuters on buses, trains, and subways who rely on navigation, tickets, and accessibility on the go and don't want to wait for a free power outlet. For festival and concert-goers who are without charging options for hours and need their smartphone for photos, meeting points, and payment functions. For frequent travelers who want an emergency reserve in their pocket between terminals, taxis, and hotels. For hikers and day-trippers who don't want to carry weight in their backpack but still don't want to be without emergency power. Also as a practical souvenir or small gift for tech enthusiasts, students, and anyone who uses their smartphone intensively and regularly finds themselves in the red battery zone.

Charge, plug in, keep using

Fully charge the power bank via the corresponding port before first use until the status indicator signals a full charge. For emergency charging, fold out the USB-C connector and plug it directly into the smartphone's charging port – the device will automatically start charging. The smartphone can continue to be used while charging; if the battery level is very low, it is recommended to close energy-intensive apps so that the reserve is used efficiently. After use, fold the connector back in and store the power bank on your keyring or in your bag. To clean, wipe the casing with a dry or slightly damp cloth; despite the water-repellent casing, do not immerse the power bank in water and protect the charging port from direct moisture. If not used for a longer period, recharge the power bank every three months to maintain the lithium battery's capacity and keep it ready for long-term use.

For everyone who never wants to be left with a dead battery again – with an emergency reserve that's always on your keyring.
