Ttec Power Stones Trio Review

The Ttec Power Stones Trio is a portable charging set built around one idea: keep a charged power bank ready while another one refills on its own station. The set includes two portable power banks and a charging station that tops the banks back up, so recharging does not depend on remembering to plug each bank into a wall charger. This review looks at the design and build, the capacity and output, the charging performance, and the extras in the box.

Design & Build

The design gives the set its name. Each power bank has a rough surface that resembles a stone, and the unit reviewed here is the gray model. The charging station uses LED lighting while it refills a bank, so the charge state stays visible during the process. Ttec also lists a switch guard among the set’s features.

Capacity & Output

Each power bank holds 5000 mAh, and the charging station refills the banks at up to 2.4 A. A single 5000 mAh bank recharges a current smartphone about 1.5 to 2 times, which fits a system that keeps a second bank in reserve rather than relying on one large cell.

Charging Performance

The station is what sets the routine apart. Because the set carries two banks, one charges while the other discharges: a drained bank goes onto the station, and the charged bank goes into a bag or pocket. This keeps a ready bank on hand without waiting for a cable to top it up. For a longer trip, both banks can travel together.

Extra Features

The box includes a standard micro USB cable. Ttec offers a separate Trio charge cable that carries three outputs on one lead — Type-C, Lightning, and Micro USB — so it can charge three devices from a single cable. The Trio cable is sold separately and is not part of the box.

Who Is Ttec Power Stones Trio For?

The Ttec Power Stones Trio fits users who want a charging set rather than a single power bank, and who value keeping one bank charged while the other refills on its station. Each bank covers a current phone once or twice, so users who need to recharge larger devices or want more capacity per unit can measure that against their own use before deciding.
