charmast 10000mAh Power Bank with Built-in Cables, Purple Review

charmast builds this power bank around convenience as much as capacity, integrating output cables directly into the body so a phone, tablet or earbud case can charge without needing a separate cord. Between the built-in cables and the added USB-A and USB-C ports, the bank supports up to 4 devices charging at once across 5 total outputs.

Recharging the bank itself is handled through a built-in AC wall plug, letting it plug straight into an outlet without a separate charging brick, with a Type-C input offering a second recharge method. That built-in plug is specifically what the listing frames as removing the need to carry an extra charging accessory while traveling.

An LED display shows the exact remaining battery percentage rather than a rough indicator, and pass-through charging lets a connected device keep charging while the bank itself recharges. At 0.5 pounds and a slim profile, the listing positions it for pockets, purses, backpacks and carry-on bags, with the 10000mAh capacity specifically called out as within standard flight carry-on limits.

The cell capacity is rated at 10000mAh, equivalent to 37 watt-hours, a figure the listing ties directly to flight carry-on approval limits. Built into the body are output cables covering iOS and USB-C/Micro USB connectors, supplemented by separate USB-A and USB-C ports, bringing the total to 5 available outputs for charging up to 4 devices simultaneously.

Charging the bank itself uses an integrated AC wall plug that folds into the body, removing the need for a separate charging brick, alongside a Type-C input as a backup charging method. Output is regulated at a stable 5V/3A, which the listing says is gentle on connected device batteries, with smart protection built in against over-charge, over-current and overheating.

Measuring 5.95 by 2.76 by 0.72 inches and weighing 0.5 pounds, the bank is built slim enough to slip into a pocket or bag easily. The LED display and pass-through charging are both built into the control logic, letting a user monitor exact charge level and keep devices powered even while the bank itself tops up.

For travel and daily commuting, the combination of built-in cables and a built-in AC wall plug removes two of the most common reasons a power bank ends up useless in the moment, a missing cable or a missing charging brick. Being able to charge up to 4 devices from one 10000mAh cell across 5 outputs covers most short trips without needing a second bank.

The listing's own reference figures estimate about 1.6 full charges for a newer iPhone model or about 1.2 full charges for a comparable Galaxy phone, giving a concrete sense of real-world capacity rather than just the raw mAh number. Stable 5V/3A output with built-in overcharge, over-current and overheat protection supports safe charging across different connected devices.

Because 5 outputs draw from a single 10000mAh capacity, charging multiple devices at once will split available current between them, which matters if several devices are plugged in simultaneously rather than one at a time. The LED percentage display and pass-through charging both support practical day-to-day monitoring and flexibility during use.
