Wholesale power banks Charging type (output current) Fast charging technology 2.0 (2-3A)

Portable power banks with Fast Charge 2.0 (2–3A) — power banks for wholesale and dropshipping: an output of 5V/2A or 5V/3A provides 10–15W of power, so a 6000 mAh smartphone charges in ~3–4 hours, a 4500 mAh in 2–2.7 hours, and a 3200 mAh in 1.5–2 hours. A 10,000 mAh power bank typically provides 1.3–1.7 charges for a 5,000 mAh device, and a 20,000 mAh one — 2.6–3.2; the actual efficiency is 65–75%. A 5V/2A output is suitable for LED lamps: a 10,000 mAh power bank lasts 3–4 hours, a 20,000 mAh one — 6–8 hours. The power bank itself charges from 0–100% in 5–6 hours or 10–12 hours at 2A, and faster at 3A; when charging two gadgets, the current is split. Awei power banks are often purchased wholesale in this mode as a basic ‘fast’ option without PD, when compatibility with most USB-A cables is required. When selecting external batteries wholesale, choose based on USB-A/Type-C and safety features.
