❓ Power Bank FAQ
1. What’s the difference between PD and PPS?
PD (Power Delivery) is a USB-C fast-charge standard used by iPhone and many tablets;
PPS adds fine-grained voltage steps—ideal for many Samsung models for cooler, efficient fast charging.
2. Is MagSafe the same as magnetic?
MagSafe-compatible packs snap to iPhone 12+ models and support aligned wireless charging.
Some “magnetic” banks attach with magnets but may not deliver full MagSafe features—check each product page.
3. Can I take these on a flight?
Yes—carry-on only. Most airlines allow ≤100Wh without approval (10,000mAh≈37Wh; 20,000mAh≈74Wh). Check your airline policy for exact limits.
4. How many charges will I get?
As a guide: 5000mAh ≈ ~1 phone top-up; 10,000mAh ≈ ~1.5–2 charges;
20,000mAh ≈ ~3–4 charges; 30,000mAh ≈ ~5–6 charges.
Actual results vary by device battery size and usage.
5. Do these support pass-through or charging multiple devices?
Many models support two or three outputs (USB-C/USB-A/wireless). Pass-through varies—see each product’s specs for details.
