Mobile Phone Power Supplies – Product Details & Advice
Mobile phone power supplies include power banks (outdoor battery, 10,000–30,000 mAh), car chargers (12/24 V), desk chargers (USB-C PD, Qi wireless) and multi-port charging stations for office and fleet use. Power banks with USB Power Delivery (PD, 45–65 W) also charge laptops; important for mobile employees without a socket. Car chargers with Quick Charge 3.0 or USB PD fully charge the phone during long journeys. Multi-port charging stations (4–10 ports, USB-A + USB-C) are ideal for conference rooms and reception areas.

Frequently Asked Questions
▶ How large should a power bank be for the working day? Rule of thumb: smartphone battery capacity (e.g. 4,000 mAh) times 2.5 = recommended power bank capacity (10,000 mAh for 2–2.5 charges). For full-day field service without a socket: 20,000 mAh (3–4 charges). Note: efficiency approx. 80–90% (not all mAh reach the device). Flights: max. 100 Wh permitted in hand luggage (approx. 26,000 mAh at 3.7 V). |
▶ What is the difference between Quick Charge and USB PD? Quick Charge (Qualcomm, QC 3.0/4.0): proprietary standard that charges quickly via varied voltage (5/9/12 V). Compatible with Snapdragon devices. USB PD: open standard (USB IF), works manufacturer-independently with USB-C, up to 100 W (PD 3.0) / 240 W (PD 3.1). USB PD is the more future-proof standard; many new devices (Apple, Samsung) support both. |
▶ Are power banks allowed on aeroplanes? Power banks (lithium-ion) may only be carried in hand luggage – not in checked baggage (IATA regulation). Limits: up to 100 Wh per power bank without approval; 100–160 Wh with airline approval (max. 2 pieces); above 160 Wh prohibited. Formula: mAh × Volt / 1,000 = Wh. Check the Wh indication on the power bank. |
