The VIYISI 10000mAh Power Bank is revolutionising the way Americans stay connected by offering a true “no-cable-required” charging experience. Featuring a unique integrated AC wall plug and built-in fast-charging cables, this ultra-slim 5-in-1 powerhouse eliminates the need for bulky adapters and messy wires. Whether you are commuting or travelling, its 22.5W high-speed output ensures your devices stay powered with maximum efficiency and unmatched portability.
Pros and Cons VIYISI 10000mAh Power Bank
The Advantages
- Integrated AC Plug: No extra wall chargers needed for the unit itself.
- Ultra-Slim Profile: Highly portable and travel-friendly (TSA approved).
- Built-in Cables: Simplifies your carry by removing cable clutter.
- Fast Charging: 22.5W output is superior to standard 10W or 12W chargers.
- LED Display: Clearly shows the remaining percentage of juice.
- Weight: At nearly 170g, it feels like feather-light.
The Drawbacks
- Integrated Cables: If a built-in cable is damaged, it cannot be easily replaced (though the USB-A/C ports remain functional).
- Input Limitations: While the AC plug is convenient, it recharges the power bank slower (approx. 5 hours) compared to using the dedicated 18W USB-C input port (approx. 3 hours).
- Built-in Cable Wear: If a built-in cable is eventually damaged through heavy use, it cannot be replaced. However, the external USB ports ensure the device remains functional with your own cables.
- US-Centric Plug: The integrated AC plug is a standard US 2-pin. If you are travelling to the UK or Europe, you will still need a physical plug adapter.
Technical Specifications of VIYISI 10000mAh Power Bank: A Deep Dive

Design and Portability: Engineered for the Pocket
One of the most striking features of the VIYISI 10000mAh Power Bank is its ultra-slim profile. Measuring a mere 14.9mm in thickness (roughly 0.58 inches), it is significantly thinner than many of its competitors in the 10000mAh category.
For the American audience who values sleek, minimalist aesthetics, VIYISI has hit the mark. The chassis is constructed from a high-grade ABS and PC fireproof material, providing a matte finish that resists fingerprints and offers a secure grip. Whether you are navigating the subway in New York or hiking in the Rockies, this device slides into a jeans pocket or a laptop sleeve without adding noticeable bulk.
All-in-One Convenience: The 5-in-1 Factor
The standout innovation of the VIYISI 10000mAh Power Bank is its “no-cable-required” philosophy. It features an integrated AC wall plug, allowing you to recharge the power bank directly from any standard US outlet. This eliminates the need to carry a separate wall brick and charging cable just to keep the power bank itself topped up.
Furthermore, it boasts built-in cables—typically including USB-C and Lightning—ensuring compatibility with the latest iPhone 16/15 series and Samsung Galaxy S24/S23 devices. This multi-functional approach is a game-changer for commuters who want to declutter their bags.
Performance: Fast Charging and Reliability
Equipped with 22.5W Quick Charge (QC) and 20W Power Delivery (PD) technology, the VIYISI 10000mAh Power Bank doesn’t just store energy; it delivers it at a blistering pace. In our testing at Gadget Info, we found that it could charge an iPhone 15 from 0% to 50% in approximately 30 minutes.
The 10000mAh capacity is the “sweet spot” for most users. It provides roughly 1.5 to 2 full charges for a modern smartphone, which is more than enough for a full day of heavy usage, including GPS, video streaming, and social media.
