The input also supports up to 30 W for rapid recharging (about 4 hours with a 30 W charger, sold separately). Features trickle-charge mode and a digital percentage display. Ports: Offers 3 total outputs—2 × USB-C and 1 × USB-A. Physical Properties: Dimensions are approx 15.1 × 7.1 × 2.8 cm (5.9" × 2.8" × 1.1"), weighing around 485 g (17.1 oz). Eco-friendly design using about 80% recycled materials. Fast charging and long battery life: Many users report multiple phone charges and swift recharge capabilities. Build quality & functionality: “Compact yet powerful… excellent build quality,” says one user. Digital display: Verbally praised for its accurate battery percentage readout. Weight & size: Some find the unit bulky—not ideal for lightweight travel kits. Mixed reliability reports: A few users reported early failures (e.g., short lifespan of just a few months). Efficiency varies depending on charging wattage. For low-power devices (phones, earbuds), expect around 60–70% transfer efficiency—roughly 11,000 mAh effectively usable. Some users appreciate the ability to charge devices while the power bank itself is charging (pass-through charging), although recharging can take upwards of 7 hours
