Can it really charge my iPhone 17 twice?Many 10,000mAh power banks only give me one full charge.
Yes. Its ~6,800mAh usable output provides about 2 iPhone 17 charges, 1.8 Galaxy S25 charges, or 1.5 iPad Air charges. The built-in AC plug recharges directly from an outlet.
Will the built-in cables break after a few weeks? My last charger cable failed within a month.
Yes. They feature stainless-steel tips, thicker wiring tested for 10,000+ bends, and dual-spring retraction. Free replacement is covered by our 3-year support.
Can it charge my Apple Watch and AirPods? My old power bank shuts off when charging small devices.
Yes. Its smart chip detects Apple Watch, AirPods, Galaxy Buds, and Fitbit, then activates trickle charging automatically. No button is needed.
Does it get hot while charging? Some power banks become so warm that I’m afraid to leave them plugged in.
An NTC sensor monitors heat and reduces current when needed. Each port has overcharge, overcurrent, short-circuit, and overvoltage protection for overnight charging.
What if it stops working after a few months? Will someone actually help me?
Every charger includes 3-year support. If anything goes wrong, message Charmast through . We’ll reply within 24 hours and provide a free replacement—no return or shipping fees
