The ONF77 is a 10,000mAh power bank that snaps onto magnet-compatible phones and charges them wirelessly at up to 15W. It also has two wired ports: USB-C at up to 20W PD and USB-A at up to 22.5W, so it can top up three devices at once. At 3.94 × 2.56 × 0.7 inches it slips into a pocket, and the magnets hold it against the phone while you walk or move around. It suits people with a MagSafe-style iPhone or a magnetic Android case who want cable-free top-ups; phones without wireless charging can only use the ports.

This is a slim 10000mAh magnetic power bank with wireless charging and two USB ports. It attaches to magnet-equipped phones with high-strength magnets, so it stays in place while you walk or move around. For the best alignment, use it with a magnet-compatible case or no case.
It has three outputs: a wireless pad, a USB-C port and a Smart USB-A port. USB-C Power Delivery can charge a smartphone from 0 to 50% in 30 minutes. The Smart USB-A port supports fast charging for Samsung and other compatible devices. It can charge 3 devices at the same time and provides about 2 charges for a phone.
Wireless charging works only with phones that support it. If your phone does not, charge it with a USB cable. The power bank is compact enough for pockets and bags, and it has a dual input design for recharging.
