Anker Laptop Power Bank (25K, 165W, A1695)

around £70 (price checked 14 Nov 2026)

A 25,000mAh (90Wh) laptop power bank with two built-in USB-C cables, one retractable and one that doubles as a carry strap, plus a USB-C port and a USB-A port. Each USB-C connection can supply up to 100W on its own, and 165W in total.

Why we picked it

Expert Reviews names it the best power bank for air travel and calls it fantastically flexible for the money in its review. It found that plugging in a second laptop didn't slow the first, and that the built-in cables mean there's nothing to forget. At 90Wh it sits under the 100Wh limit for carrying a power bank on a plane without the airline's approval. The downsides are weight (595g) and no wireless charging. Anker's UK store listed it at £89.98 but showed it as sold out when we checked.

Best for: Travellers and laptop users who want one bank that charges everything, cables included

Skip it if: You want something that fits in a jeans pocket, or you need wireless charging.

Capacity	25,000mAh (90Wh)
Max USB-C output	100W per port, 165W total

No. 2 · BEST VALUE

Cuktech 10 Mini

around £25 (price checked 14 Nov 2026)

A compact 10,000mAh power bank from Cuktech, with two USB-C ports (up to 55W) and a USB-A port (up to 33W), plus a small display showing the charge left.

Why we picked it

Expert Reviews makes it its best cheap power bank and calls it one of the best mid-capacity banks it has reviewed, praising the fast ports, the clear display and the size (216g). The headline 55W only applies to laptops and some Xiaomi phones: Expert Reviews saw about 40W from an Android phone. There's no wireless charging. Cuktech launched it in the UK at £24.99, and it has sold for between about £21 and £27 since.

Best for: Anyone who wants a small, cheap pack to keep a phone going through a long day

Skip it if: You want to charge a laptop properly, or you'd rather drop your phone on a wireless pad.

Key specs
Capacity	10,000mAh
Max USB-C output	55W
Ports	2 USB-C, 1 USB-A
Weight	216g
Hand luggage	Yes, well under 100Wh

No. 3 · BEST PREMIUM

Anker Prime Power Bank (26K, 300W, A110A)

around £160 (price checked 14 Nov 2026)

Anker's flagship power bank, with 26,250mAh (99.75Wh), two USB-C ports that can each deliver up to 140W, a USB-A port and 300W in total. A touchscreen and a Bluetooth app show what each port is doing. It can recharge at up to 250W using both USB-C ports.

Why we picked it

Expert Reviews names it the best power bank overall and calls it the ultimate mobile power bank, praising charging speeds no rival matched and the genuinely useful display and app. Anker rates it at 99.75Wh and calls it hand-luggage approved, so it just squeezes under the 100Wh airline limit. It weighs about 600g and the glossy panel picks up fingerprints. Anker's UK store lists it at £179 but showed it as sold out when we checked. Expert Reviews tracked an average of about £162 over six months and a Black Friday deal at £129, so it's worth waiting for a sale.

Best for: People who travel with two laptops' worth of kit and want the fastest charging they can carry onto a plane

Skip it if: You're on a budget, or you mostly charge a phone; it's far more than you need.

Key specs
Capacity	26,250mAh (99.75Wh)
Max USB-C output	140W per port, 300W total
Ports	2 USB-C, 1 USB-A
Weight	About 600g
Hand luggage	Yes, just under 100Wh

UGREEN Nexode Power Bank 20000mAh 145W (PB771)

around £100 (price checked 14 Nov 2026)

A 20,000mAh power bank shaped like a small tower, with a 100W USB-C port, a 45W USB-C port, a USB-A port and a fold-out magnetic Qi2 pad (15W) for iPhones and other Qi2 phones. It can deliver 145W in total.

Why we picked it

Expert Reviews picks it as the best power bank for charging several devices, calling it a mini-tower of power. In its review it measured about 98W and 42W from the two USB-C ports at the same time, and liked the MagSafe-style pad. It's bulkier and heavier (555g) than most rivals, and it doesn't recharge especially quickly. UGREEN's UK store had it on sale when we checked, and Expert Reviews lists it at £90 to £100.

Best for: Desks, hotel rooms and bags where you want to charge a laptop, a phone and earbuds at once

Skip it if: You want something slim; this is a chunky block rather than a pocket pack.

Key specs
Capacity	20,000mAh
Max USB-C output	100W (second port 45W), 145W total
Ports	2 USB-C, 1 USB-A, Qi2 wireless pad
Wireless	Qi2, 15W
Weight	555g
Hand luggage	Yes, under 100Wh

No. 5

INIU SnapGo Air

around £45 (price checked 14 Nov 2026)

A thin 10,000mAh magnetic power bank (about 14mm thick and 196g) with Qi2.2 wireless charging at up to 25W and two USB-C ports at up to 45W, so it can also top up a small laptop by cable.

Why we picked it

Expert Reviews makes it its best MagSafe power bank, recording the fastest wireless charging it has seen and a steady 43.5W into a laptop by cable. TechRadar also recommends it, praising the speed, the slim design and the small display. Some phones didn't reach their full wireless speed, and 10,000mAh won't stretch to many charges. INIU's UK store lists it at £49.99 but showed it as sold out when we checked; Expert Reviews' guide, updated on 11 November 2026, lists it at around £45.

Best for: iPhone and Qi2 Android owners who want a slim pack that snaps on the back of the phone

Skip it if: You need more than about one full phone charge, or you want a USB-A port.

Key specs
Capacity	10,000mAh
Max USB-C output	45W
Wireless	Qi2.2 magnetic, 25W
Ports	2 USB-C
Weight	About 196g
Hand luggage	Yes, well under 100Wh

No. 6

Anker Nano Power Bank (10K, 45W, built-in retractable cable)

around £45 (price checked 14 Nov 2026)

A 10,000mAh pocket power bank with a retractable USB-C cable (about 70cm) built in, plus a separate USB-C port and a USB-A port, and a small display showing charge level and power flow. The cable and USB-C port give up to 45W.

Why we picked it

TechRadar calls it highly practical thanks to the retractable cable and handy display, and found overall performance good. It also found it throttles when warm, recharges fairly slowly (about two hours), and doesn't have the power for hungrier devices. With several devices plugged in, total output drops to 22.5W. Anker's UK store lists it at £49.99, and it was available with a £12 coupon when we checked.

Best for: People who always forget a cable and want a small phone pack with one built in

Skip it if: You want to charge a laptop at full speed, or two devices quickly at once.

Key specs
Capacity	10,000mAh
Max USB-C output	45W (22.5W total with several devices)
Ports	Built-in retractable USB-C cable, 1 USB-C, 1 USB-A
Weight	232g
Hand luggage	Yes, well under 100Wh

How we chose

We started with the current power bank guides from Expert Reviews, TechRadar and Pocket Tactics, and the individual reviews behind them. That gave us a shortlist of about a dozen, which we narrowed to banks we could find on sale in the UK, from pocket-sized phone packs at around £25 to a 300W laptop charger.

For each one we looked at three things: how much it holds (mAh, and Wh where the maker states it), how much power a single USB-C port can deliver, and whether you can take it on a plane. A bank with plenty of capacity but a slow port will still take hours to charge a laptop, so the wattage of the best USB-C port matters as much as the size.

Air travel rules shaped the list. The UK Civil Aviation Authority allows power banks up to 100Wh in hand luggage without asking the airline, so every pick here sits under that line. Anything bigger needs the airline’s approval, which is a hassle at check-in, so we left those out.

We left out the Anker MagGo Power Bank (10K) and the Iniu P50-E1, both TechRadar picks, because we couldn’t confirm a current UK price for them. Three of our picks (the Anker A1695, Anker Prime and INIU SnapGo Air) showed as sold out on their makers’ UK stores when we checked, so their prices are based on recent UK listings and reviews.

This guide is based on manufacturer specs, retailer listings, expert reviews and the CAA’s published rules, listed below. We haven’t used these power banks ourselves. Prices are typical UK prices on the date shown beside each pick, and they move around Black Friday and Christmas.

FAQs

Can I take a power bank on a plane from the UK?

Yes, but only in your hand luggage, never in checked bags. The UK Civil Aviation Authority allows power banks up to 100Wh without the airline's approval, and 100Wh to 160Wh only with it. You can carry no more than two per person, and the CAA says you shouldn't recharge them on board or use them to charge devices during the flight. Airlines can set stricter rules, so check yours before you fly.

How do I work out a power bank's Wh rating?

Most banks print it on the label. If yours only shows mAh, the CAA's formula is Ah x V = Wh, where Ah is the mAh figure divided by 1,000 and V is the battery's nominal voltage. Anker rates its 26,250mAh Prime at 99.75Wh, which is why it just squeezes under the 100Wh limit; every other bank in this guide is smaller.

What USB-C wattage do I need to charge a laptop?

Check the wattage of the charger that came with your laptop and aim for a power bank port that matches it. A 45W port, like those on the INIU SnapGo Air and Anker Nano, can top up a small laptop slowly. For a larger laptop, look for 100W or more on a single USB-C port, as on the Anker A1695, the UGREEN PB771 and the Anker Prime.

How many phone charges will a 10,000mAh power bank give?

Fewer than the number suggests, because some energy is lost as heat and voltage conversion. TechRadar estimates about 1.3 charges of a modern phone from the 10,000mAh INIU SnapGo Air. If you want several charges or a laptop top-up, choose 20,000mAh or more.
