Wireless & Magnetic Charging

Learn how to get predictable Qi2 power bank performance: match phone support, use e-marked cables, mind heat and cases, and read real Wh, not mAh.

Learn why MagSafe banks deliver less than claimed and how Qi2 certification, case thickness, and proper Wh labeling ensure reliable, airline-ready charging.

Understand the physics and protocol negotiation behind Qi wireless charging - why alignment, distance, case thickness, heat, and MagSafe/EPP support determine real-world speed and efficiency. Use these insights to choose a power bank, estimate true delivered capacity, and know when to switch to wired charging for predictable results.

Learn why mAh ratings overstate real-world output - after voltage conversion, wireless inefficiency, and heat - and translate specs into usable power with simple Wh math. Apply a quick checklist (Wh label, verified efficiency, UN38.3 match, thermal derating) to choose reliable, airline‑safe power banks.
