A ZDNET teardown found a graphene coating inside the Momax Q.Mag X, confirming the cooling claim behind the pack’s notably low heat during testing.
The 5,000 mAh battery pack stayed only slightly warm under use, with no hot spots while charging or being charged—an uncommon result for a 15W magnetic wireless power bank.
The disassembly also showed heavy use of sealant, adhesive and thermal silicone, alongside what the reviewer described as top-tier internal components and solid assembly.
Momax’s Q.Mag X pairs that build quality with an 8.3 mm, 125 g design, 15W Qi2 wireless charging, 20W USB-C output and dual-device charging for just under $30.
How does a sub-$30 power bank use graphene while pricier competitors from major brands reportedly overheat?
Is graphene the key to solving the overheating problem inherent in the new, mandatory Qi2 wireless charging standard?
Beyond impressive teardowns, what is the real-world impact of a graphene coating on a battery's long-term health and safety?
