Black Friday Power Bank Deals

Capacity in milliamp hours is the headline figure, but the useful number is lower than the one printed on the case, because voltage conversion loses roughly a third along the way. So a 10000mAh bank delivers something closer to 6500mAh into a phone, which is one full charge for most handsets and a little over. Work from that. Five thousand milliamp hours is a pocket sized top up for a day out. Ten thousand is the sweet spot for a phone and the size most people should buy, since it still fits a jacket pocket and covers a weekend. Twenty thousand and upward covers a tablet, several phones or a few days away, and is where the weight starts to be noticeable. Output is the second thing to check and the one most often ignored. A bank rated at 18W will charge a modern phone quickly where a 10W one will not, and a laptop needs 45W to 100W over USB-C Power Delivery, so a bank without PD will not charge a laptop at all no matter how large its battery. Look at how many devices it can charge at once and whether the total output is shared or per port. Pass through charging, where the bank charges devices while itself being charged, is worth having. Wireless charging pads built into a bank are convenient but slower and warmer, so treat that as a bonus rather than a reason to buy. Note that airlines limit lithium capacity in cabin baggage, so check the rating before flying.

Beyond the bank itself, the cable is what limits real world charging speed as often as anything else, and a cheap cable will cap a fast charger. A built in cable saves the one you always forget, and a bank with both USB-C and Lightning built in covers a mixed household. For anything bigger than charging phones and laptops, a portable power station with mains sockets is the right tool instead.

Black Friday falls on Friday 27 November 2026 and Cyber Monday on Monday 30 November, though reductions here run through the season rather than only across that weekend, so anything showing a saving is genuinely reduced today. Anker accounts for most of the reduced range. The full year round range sits in Power Banks, with everything currently reduced in Power Stations and Power Banks Sale. Larger units with mains sockets are in Black Friday Power Station Deals, and cables and chargers in Mobile Phone Accessories.
