What is the best power bank capacity for load-shedding in South Africa?

A 20,000mAh power bank is the sweet spot for load-shedding. It holds enough for several phone charges plus a tablet or earbuds across a 2-4 hour outage while staying compact and flight-legal. To keep a laptop running through an outage, step up to a 25,000mAh or larger USB-C PD model.

How many phone charges does a 20,000mAh power bank give?

Around 3-4 full charges for a typical smartphone, not the 5+ the raw number suggests. Voltage conversion and cable losses mean usable output is roughly 60-70% of the rated 20,000mAh, so plan around the real-world figure rather than the label.

Can a power bank charge a laptop in South Africa?

Yes, if it has a USB-C Power Delivery (PD) output. A 65W PD port charges most ultrabooks and a MacBook Air, 100W covers larger and gaming laptops, and PD 3.1 banks reach 140W. Match the PD wattage to your laptop's original charger for full-speed charging.

What is USB-C Power Delivery (PD) and why does it matter?

USB-C PD is the fast-charging standard that lets a single port safely deliver anything from 18W to 140W, negotiating the right voltage for each device. It is what allows one power bank to fast-charge a phone, tablet and laptop, and it is now the default on modern hardware.

Are power banks allowed on flights from South Africa?

Yes, in carry-on hand luggage only, as they are prohibited in checked bags. Capacity up to 100Wh (about 27,000mAh) is allowed without approval, and 100-160Wh needs airline sign-off. A 20,000mAh pack sits near 74Wh, so it is cabin-legal on all major carriers.

How long does a large power bank take to recharge?

It depends on the input. With a slow 18W charger a 30,000mAh bank can take 6+ hours, while a 45-65W USB-C PD input typically refills it in about 3-4 hours on SA 230V mains. If fast turnaround matters, check the bank's rated input wattage before buying.

Can I charge two devices at once from one power bank?

Yes. Multi-port models charge a phone alongside a tablet or earbuds, though total output is shared across ports so per-device speed drops. For fast simultaneous charging, choose a bank rated for high combined wattage across its USB-C and USB-A ports.

What safety features should a good power bank have?

Built-in protection against over-charging, over-current, short circuits and overheating, plus recognised certification such as CE and RoHS. Genuine lithium cells and proper quality control matter more than the mAh figure, since cheap counterfeit packs often overstate capacity and run hot.
