Frequently asked questions
What is Mine Power Cap?
Mine Power Cap is a portable-power brand. We design and present power banks, high-capacity battery packs and "power caps" — the compact energy packs that keep phones, laptops and outdoor gear charged away from a wall socket.
What is a "power cap"?
It is our name for a portable battery pack: a self-contained cap of stored energy you carry with you. Some are pocket-sized for a phone top-up, others are high-capacity packs that recharge a laptop several times.
How do I choose the right capacity?
Think in device charges, not just numbers. A slim pack is ideal for a day's phone top-ups; a high-capacity pack suits laptops, tablets or multi-day trips. Each category page explains what a pack is built for.
What about USB-C and fast charging?
Modern packs use USB-C Power Delivery to charge phones and many laptops quickly. Our Fast-Charge & USB-C PD category groups the packs made for higher-wattage charging.
