Will this really charge my iPhone 17 twice? Many 10000mAh power banks only give me one charge.
Yes. iPhone 17 (~3,322mAh) gets ~2 full charges. Our high-efficiency circuit delivers ~6,800mAh usable output — not just a theoretical number. Galaxy S25 ~1.8x, iPad Air ~1.5x. And the built-in AC plug means any outlet recharges it directly.
Will the built-in cables break after a few weeks? My last charger cable died in a month.
Our cables are built differently. Reinforced stainless steel connector tips, thicker wiring rated for 10,000+ bend cycles, and a dual-spring retraction mechanism. Covered by our 3-year support — free replacement,
Can this charge my Apple Watch and AirPods? My old power bank shuts off with small devices.
Yes. A built-in smart chip auto-detects low-draw devices like Apple Watch, AirPods, Galaxy Buds, and Fitbit. It switches to trickle charge mode automatically — no button needed. Just plug in and it handles the rest safely.
Does this get hot while charging? Some power banks get so warm I am afraid to leave them plugged in.
An NTC thermistor monitors temperature in real time and auto-reduces current if it gets warm. Every port has overcharge, overcurrent, short-circuit, and overvoltage protection. Safe for overnight charging.
What if it stops working after a few months? Will someone actually help me?
