Our reviews of the best power banks and fast chargers UK
Our reviews of the best power banks and fast chargers UK cover three power banks first, then two USB-C wall chargers. For each one, we list the key specs from the listing and the price we saw on 11 November 2026.
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 the best power banks and fast chargers UK
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 in the best power banks and fast chargers UK
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.
Which charger or power bank suits you?
- Best budget slim power bank: INIU 10,000mAh 22.5W, £14.96 when we checked.
- Best compact power bank with a built-in cable: Anker Nano 10,000mAh 30W, £29.99 when we checked.
- Best for laptops and high-power devices: UGREEN Nexode 20,000mAh 130W, £49.99 when we checked.

- Best multi-port 65W charger: UGREEN Nexode 65W charger, £20.99 (Prime) when we checked.
As a rough guide, a 10,000mAh power bank will top up most phones about twice. A 20,000mAh model is better for long trips, tablets and some laptops, but it is heavier.
Buying guide: understanding power bank and charger specs
Capacity in mAh and Wh
Capacity is usually listed in mAh. Airlines use watt-hours (Wh) instead, which is often printed on the power bank itself. Bigger numbers mean more charges, but also more weight.
Output in watts
The wattage tells you how fast a power bank or charger can deliver power. Around 20–30W is plenty for fast charging most phones. Laptops usually need more, which is why the UGREEN 130W power bank and the 65W charger are in this list.
USB-C and Power Delivery
Most new phones and laptops charge over USB-C using the Power Delivery (PD) standard. Check that the charger and the cable both support the speed you need, as a slow cable can limit fast charging.
How many ports?
A multi-port charger can replace several plugs, which is handy on a desk or in a hotel room. Remember that the total wattage is shared when you charge more than one device at once.
Buy from known brands
Cheap, unbranded chargers can be poorly made. Stick to known brands, buy from a reputable seller and avoid anything that gets unusually hot or arrives damaged.
Travel rules and safety
Power banks must normally go in your hand luggage, not your hold bag. The GOV.UK hand luggage rules explain the basics, and your airline may have extra limits based on watt-hours. Electrical Safety First also has useful power bank safety advice.

Best power banks and fast chargers UK for travel
For travel, think about weight, ports and the cables you carry. A 10,000mAh power bank is light enough for a day bag and will top up most phones a couple of times. A 20,000mAh model makes more sense for long trips or for charging a tablet or a laptop, but it is heavier.
A single multi-port charger can replace several plugs in a hotel room. In our list, the UGREEN Nexode 65W charger has three ports, which makes it one of the best power banks and fast chargers UK travellers can pack. If you travel abroad, remember that you will still need a travel adaptor for non-UK sockets.
Check your airline’s rules before you fly, especially for larger power banks. Keep the power bank in your hand luggage, protect the ports from keys and coins, and do not charge it while it is buried in a bag.
How to tell if a charger is genuine
Fake chargers and power banks do turn up online. They can look almost identical to the real thing but may lack proper safety protection. Buy from Amazon or the brand’s own store front, check the seller name and be wary of prices that look too good to be true.
A genuine product should have clear markings, a proper brand name and a UKCA or CE mark. If something feels unusually light, gets very hot or smells of burning, stop using it. These checks apply to all of the best power banks and fast chargers UK shops sell, not just the cheap ones.
Best power banks and fast chargers UK for students and commuters
Students and commuters tend to need a light power bank that fits in a pocket and a fast charger for the desk. The Anker Nano power bank with its built-in cable is the tidiest option for a bag, and the Anker Nano 30W charger is small enough to leave plugged in at home. If you also need to charge a laptop, the UGREEN 65W charger covers phone and laptop with one plug.
Looking for a new laptop as well? Our guide to the best budget laptops for students UK covers models from around £250.
Whichever you choose, the best power banks and fast chargers UK buyers can get are the ones matched to their devices. Check your phone’s or laptop’s charging speed first, then pick a charger that meets it. That simple check is the quickest way to choose from the best power banks and fast chargers UK shops list without overspending.
Best power banks and fast chargers UK: 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.
Which of the best power banks and fast chargers UK shoppers can buy is best for a laptop?
In our list, the UGREEN Nexode 20,000mAh 130W power bank and the UGREEN Nexode 65W charger are the ones aimed at laptops. Check your laptop’s charging wattage and that it charges over USB-C before you buy.
Can I leave a power bank plugged in all the time?
It is better not to. Unplug it once it is full, store it somewhere cool and dry, and stop using it if it swells, smells or gets very hot.
Is GaN better than a normal charger?
GaN (gallium nitride) chargers can be smaller and run cooler for the same power. They are not essential, but they are a good choice if you want a compact multi-port charger.
Our verdict on the best power banks and fast chargers UK
For most people, the Anker Nano 10,000mAh power bank with its built-in cable is the most convenient pick among the best power banks and fast chargers UK shops sell. On a budget, the INIU is great value, and laptop users should look at the UGREEN models. Prices on the best power banks and fast chargers UK retailers list can change daily, so check before you buy.
