The best power banks and fast chargers UK shoppers can buy right now range from a slim £15 phone pack to a 130W laptop battery and a compact 65W wall plug. We’ve checked today’s Amazon UK prices and stock on five popular Anker, UGREEN and INIU options.
A 10,000mAh bank is usually enough for a couple of phone charges; 20,000mAh is more useful if you also carry a tablet or a USB-C laptop. Prices were checked on 11 November 2026 and may change, so confirm the live figure on the retailer page before you buy.

INIU 10,000mAh 22.5W Power Bank – £14.96
Best for: Best budget slim power bank · Amazon UK price: £14.96 · Rating: 4.6/5 (29,939 ratings)
If you mainly want a slim phone charger for a bag or coat pocket, this INIU 10,000mAh pack is the cheapest pick here. The listing specifies 22.5W PD 3.0 and QC 4+ charging, a USB-C port that works for both input and output, extra USB-A ports, an LED percentage display, a small flashlight and a travel pouch. A short USB-C cable is in the box. It will not charge a laptop at useful speeds, and today’s buy box is sold by TopStar GETIHU Accessory rather than Amazon itself, so check delivery and returns before you checkout. In stock at £14.96, dispatched by Amazon.
Anker Nano Power Bank 10,000mAh 30W (Green) – £29.99
Best for: Best compact power bank with a built-in cable · Amazon UK price: £29.99 · Rating: 4.5/5 (10,453 ratings)
Anker’s Nano pack is the one to choose if you want 30W charging without carrying a spare USB-C lead. The built-in cable charges phones, tablets and some smaller laptops, and also recharges the power bank itself. There is a second USB-C port and a USB-A port, plus a colour percentage display. Anker quotes 30W two-way charging, a compact 10.4 × 5.2 × 2.6 cm body and an 80% recycled-plastic casing. Some reviewers mention mixed charging speed and the odd reliability issue, so keep the returns window in mind. Dispatched by Amazon and sold by AnkerDirect UK, in stock at £29.99.
UGREEN Nexode 20,000mAh 130W Power Bank – £49.99
Best for: Best for laptops and high-power devices · Amazon UK price: £49.99 · Rating: 4.5/5 (4,935 ratings)
This is the serious travel pack if you need to top up a USB-C laptop as well as a phone. UGREEN lists a 20,000mAh (72Wh) capacity, two USB-C ports and one USB-A port, with up to 100W from the main C1 port and 30W from C2, plus a TFT display for battery level, voltage, current and wattage. It weighs about 480g and is closer to a small bottle than a credit card, so it belongs in a backpack rather than a pocket. The listing says the capacity is airline-friendly, but always check your carrier’s rules. Dispatched by Amazon and sold by UGREEN GROUP LIMITED UK, in stock at £49.99.
Anker Nano 30W USB-C Charger (Black) – £13.99
Best for: Best compact 30W wall charger · Amazon UK price: £13.99 · Rating: 4.7/5 (1,335 ratings)
For everyday phone and tablet charging, this tiny GaN plug is hard to beat. It has a single USB-C port with up to 30W output, PPS support and a foldable UK plug, and Anker quotes ActiveShield 3.0 temperature monitoring plus a casing made with 75% recycled plastic. A cable is not included. It will top up a MacBook Air slowly, but it is not a multi-port laptop charger. Dispatched by Amazon and sold by AnkerDirect UK, in stock at £13.99.
UGREEN Nexode 65W 3-Port GaN Charger – £20.99 (Prime)
Best for: Best multi-port 65W charger · Amazon UK price: £20.99 (Prime) · Rating: 4.6/5 (3,977 ratings)
If you want one wall plug for a laptop, phone and earbuds, this foldable 65W GaN charger has two USB-C ports and one USB-A port. A single USB-C device can take up to 65W; with two USB-C devices connected, UGREEN says power is shared (typically 45W and 20W), and the USB-A port is listed at up to 22.5W. The UK pins fold away for travel, and a cable is not included. Amazon showed a Prime member price of £20.99 when we checked, dispatched by Amazon and sold by UGREEN GROUP LIMITED UK. Confirm the live price at checkout if you are not a Prime member.
How we chose these chargers
Every product here was listed as in stock in new condition on Amazon UK when we checked the product page on 11 November 2026. We stuck to well-known USB-C power banks and wall chargers and quoted only the features on those listings. We have not invented discounts or ‘was’ prices, and we dropped any model that had no clear featured price, including an INIU 25,000mAh 100W pack on the day we looked.
Customer ratings are the live totals on each page. Claimed wattage depends on a compatible cable and a device that actually requests that power, and real-world capacity is always lower than the headline mAh figure once conversion losses are included.
What to look for
Capacity and wattage. 10,000mAh is a sensible everyday size for phones. 20,000mAh (typically around 72–74Wh) is still widely accepted in UK cabin bags, but check your airline. For laptops, look for at least 65W on a wall charger or a 100W-class USB-C port on a power bank.
Ports, cables and plugs. A built-in USB-C cable is genuinely useful on a power bank. On a wall charger, foldable UK pins are easier to pack, and a second or third port saves you taking two plugs on a trip. A cable is not included with either wall charger here, so budget for a decent USB-C lead if you do not already have one.
Frequently asked questions
Can I take a 20,000mAh power bank on a plane?
Usually yes, in cabin baggage, if it is under 100Wh. The UGREEN 20,000mAh pack is listed at 72Wh. Spare power banks should stay in your hand luggage, not the hold, and some airlines cap how many you can carry, so check before you fly.
Will a 30W charger charge a laptop?
It can trickle-charge or maintain a smaller USB-C laptop such as a MacBook Air during light use, but it will be slow. For proper laptop charging, a 65W wall charger or a high-wattage power bank such as the UGREEN 130W model is a better match.
Do I need a special cable for fast charging?
Yes. USB-C Power Delivery only reaches the advertised wattage if both the cable and the device support it. A cheap or very long cable can limit a 65W or 100W charger to phone-level speeds, so use a USB-C to USB-C lead rated for the power you want.
