Small cell, specific job: under-1,000mAh power banks are the tier built for pocket carry, keyrings, gift programs and single-charge top-ups. The shells are compact by definition – card format, keychain format, lipstick format – which caps the cell in the 200–1,000mAh range. Typical configuration (customizable per order): 500mAh or 1,000mAh Grade-A cell, 5V/1A output, one USB-A port or a built-in Lightning/USB-C tip.
Be clear about what this tier does: it will not refill a modern phone from empty. It buys a few hours of talk time, one emergency call, or a branded giveaway that a client actually keeps. If you need a full recharge, step up to the 1,000–5,000mAh tier. Every model here ships on the same terms as the rest of the catalog – factory-direct pricing from MOQ 100 pcs, custom logo and packaging, capacity and port layout locked to your order rather than to a spec sheet.
