LISEN 15W Qi2 Magnetic Power Bank

"Most magnetic power banks feel like carrying a brick taped to your phone. We brought this model in because the 0.38-inch thickness sits flush and comfortable in hand, while the 13N magnets lock on securely."

"The slender housing stays well below the camera bump on recent iPhones, so it won't interfere with your lens alignment or MagSafe cases. Just keep in mind that non-magnetic cases will severely weaken the hold."

"During thermal testing, the internal NTC control kept surface temps right around 105°F under full load, which is noticeably cooler than standard battery packs. Wireless efficiency stays consistent up through 75% capacity."

"At under thirty dollars for Qi2 certification, this is one of the better values in the -slim category. You're getting true 15W wireless output where most competitors in this price bracket max out at 7.5W."
