Keep a top-up and a phone grip together in your daily kit. The Techsmarter MagBoost 5,000mAh magnetic power bank pairs wireless charging for a compatible MagSafe-equipped iPhone with a slide grip that also works as a stand. Use it for a steadier one-handed hold or hands-free viewing while your phone charges. An 18W USB-C output gives this portable charger a wired fast-charging option too. Attach it directly to a supported phone or through a MagSafe-compatible case.
