The Sharge Icemag 3, a 10,000mAh Qi2.2 MagSafe battery with 25W wireless output and a 35W USB-C cable lanyard, is available for $69.90 on Amazon Prime with a free 60W USB-C cable included.
How the Icemag 3 improves on typical magnetic power banks
The device combines wireless charging for iPhone 16-series and newer models with passthrough capability via its USB-C port, allowing simultaneous charging of the battery and a connected device. Its built-in kickstand and transparent design featuring an LED-cooled fan differentiate it from slimmer but less feature-rich competitors. The 35W USB-C cable doubles as a lanyard, adding portability not commonly found in this category.
Why the current pricing matters for consumers and competitors
At $69.90 with a free cable, the effective cost drops below $70 for a 10,000mAh Qi2.2 power bank with 25W wireless and 35W wired output — a segment where similar models often exceed $90 without accessories. Sharge’s direct storefront offer at $67.92 with code ICE15 undercuts Amazon’s deal slightly but omits the free cable, creating a tiered value proposition. This pricing pressure could force rivals like Anker or Belkin to adjust bundles or discount older Qi2 models to maintain market share.
What the inclusion of active cooling suggests about thermal limits in fast wireless charging
The Icemag 3’s see-through housing reveals an LED-packed fan that activates during recharging, indicating Sharge is addressing heat dissipation challenges inherent in sustained 25W wireless output. Most magnetic power banks rely on passive cooling, which can throttle speeds or reduce battery longevity under load. By integrating active thermal management, Sharge may be setting a new benchmark for performance consistency in compact Qi2.2 designs, though long-term durability of the moving parts remains unverified in the source.
Does the Icemag 3 support passthrough charging?
Yes, the Sharge Icemag 3 includes a USB-C port that enables passthrough charging, allowing the battery to recharge while simultaneously powering a connected device.
Is the free USB-C cable included with the Amazon Prime offer compatible with fast charging?
The free cable is a basic 60W USB-C cable, which supports fast charging for most smartphones and laptops, though it is not the same 35W lanyard cable built into the battery unit itself.
