Anker 3000mAh Magnetic Power Bank

"We picked this over thicker 10,000mAh bricks because most people just need enough juice to reach bedtime. The 9N magnet force is solid—it snaps cleanly onto the back of an iPhone and doesn't rotate or slide around when slipped into a tight pocket."

"At 8.6mm thick, it fits neatly on standard MagSafe cases without blocking the camera bump on smaller base-model phones. Just note that non-magnetic cases will cause it to slide off immediately, so stick to MagSafe-compatible covers or bare phones."

"Wireless power banks usually get uncomfortably hot, but internal graphene sheets kept this one right around 104 degrees Fahrenheit under load. Wireless output hit the full 15W mark on Qi2 devices, while the USB-C port held a stable 20W wired output."

"At $54.99, you are paying a slight for the -thin form factor and official Qi2 certification. You can find bulkier 5,000mAh magnetic packs for less money, but nothing near this thin that stays this cool under active load."
