Whether you’re commuting across London, hiking in the Lake District, or sitting through back-to-back meetings, a flat battery at the wrong moment is genuinely stressful. Portable chargers — also known as power banks — promise to solve that problem. But are portable chargers worth it in 2026, or are they just another gadget collecting dust in a drawer? The short answer is yes — for most people, a good power bank is one of the most practical tech accessories you can buy. This guide explains exactly what to look for, which models offer the best value at every price point, and who will benefit most from owning one.
What to Look For in a Portable Charger
- Capacity (mAh): This tells you how much charge the power bank holds. A 10,000mAh bank will fully charge a modern smartphone roughly two to three times, while a 26,000mAh model can top up a laptop or keep multiple devices going for several days.
- Charging speed (wattage): Look for at least 18W Power Delivery (PD) output for fast charging. Premium models offer 65W or higher, which is fast enough to charge a MacBook or iPad at full speed.
- Number and type of ports: USB-C ports with Power Delivery are essential in 2026. Having at least one USB-A port for older cables is still useful, and wireless charging is a handy bonus for compatible devices.
- Size, weight, and airline rules: Anything over 100Wh (roughly 27,000mAh) is banned in aircraft cabins. If you travel by plane, keep capacity below that threshold and check individual airline policies before you fly.

Our Top Picks
Anker 737 Power Bank (PowerCore 26K)
The Anker 737 is the power bank we’d recommend to almost anyone who wants a single device to handle everything. With 26,800mAh of capacity and a 140W maximum output, it can charge a MacBook Air from flat in around 90 minutes, while simultaneously topping up a smartphone via its USB-A port. The built-in display shows exact battery percentage, remaining charge time, and wattage — genuinely useful rather than gimmicky. It recharges itself in just under two hours using a 140W USB-C charger. The build quality feels premium, and Anker’s reputation for reliability is well-earned after years at the top of the market.
Pros
- Charges laptops, tablets, and phones simultaneously
- Helpful digital display with real-time stats
- Recharges itself extremely quickly
Cons
- Heavier than smaller power banks (around 680g)
- 140W wall charger sold separately
Belkin BoostCharge 10K Power Bank
For students, commuters, or anyone who just needs a reliable top-up for their phone each day, the Belkin BoostCharge 10K is hard to fault at this price. It holds enough power for two to three full smartphone charges, fits comfortably in a coat pocket, and includes both USB-C and USB-A ports. It’s not the fastest charger in the world — output tops out at 12W — but for the money it offers excellent day-to-day dependability. Belkin as a brand is trusted by Apple and widely stocked in UK high street shops, so warranty support is easy to access. It’s a no-fuss, no-nonsense choice for light to moderate use.
Pros
- Slim and pocket-friendly design
- Reputable brand with good UK warranty support
- Both USB-C and USB-A ports included
Cons
- No fast charging — 12W max output
- LED indicator rather than precise battery display
Mophie Powerstation Pro XL
Mophie has long been a favourite among Apple enthusiasts, and the Powerstation Pro XL justifies its premium price tag with a combination of beautiful build quality, versatile charging options, and genuine airline-friendly capacity. At 20,000mAh, it sits comfortably under the 100Wh aircraft limit, making it ideal for frequent flyers. The built-in wireless charging pad handles up to 15W, so you can drop your iPhone or AirPods on top without fumbling for a cable. Wired USB-C output reaches 45W — plenty for phones and tablets. The aluminium chassis feels genuinely luxurious, and Mophie’s two-year warranty provides extra peace of mind for the investment.
Pros
- Built-in wireless charging pad
- Airline-safe capacity (under 100Wh)
- Premium aluminium build with two-year warranty
Cons
- Expensive compared to equally capable rivals
- 45W wired output won’t fully charge a laptop
Who Should Buy a Portable Charger?
Almost everyone who uses a smartphone regularly will benefit from owning a power bank, but some people will notice the difference more acutely than others. If you commute by public transport, spend long days away from your desk, travel frequently, or work in an outdoor or event-based role, a portable charger will quickly become one of your most-used accessories. Parents keeping children entertained on long journeys, festival-goers, remote workers, and anyone relying on their phone for navigation or mobile payments will find a power bank an essential rather than optional purchase.
On the other hand, if you work from home most of the time, have easy access to plug sockets throughout the day, and rarely spend more than a few hours away from a charger, a smaller and cheaper model is all you’ll ever need — or you may decide a power bank isn’t a priority at all. That said, even light users often find they reach for one more than they expected once they own one. At £22 for a decent budget option, the cost of entry is low enough that most people will find it worthwhile.
Final Verdict
Are portable chargers worth it in 2026? Absolutely — for the vast majority of people. The Anker 737 is the standout choice for power users and frequent travellers who need serious capacity and fast charging. The Belkin BoostCharge 10K is the smart pick for anyone who wants reliable everyday performance without spending much. And the Mophie Powerstation Pro XL is the premium option for those who want wireless charging and exceptional build quality in an airline-friendly package. Whatever your lifestyle, there’s a power bank here that will pay for itself the first time it saves you from a dead battery in a critical moment.
Frequently Asked Questions
Are portable chargers allowed on planes?
Yes, but only in your carry-on luggage — never in checked baggage. Most airlines allow power banks up to 100Wh (roughly 27,000mAh), though some budget carriers have stricter limits. Always check with your specific airline before you fly, as rules can vary.
How many times can a 10,000mAh power bank charge my phone?
A 10,000mAh power bank will typically provide two to three full charges for a modern smartphone, depending on your phone’s battery size. A typical iPhone 16 has around a 3,500mAh battery, so in real-world conditions (accounting for conversion losses) you can expect roughly 2.5 charges from a 10,000mAh bank.
Do portable chargers damage your phone’s battery?
No — a quality power bank from a reputable brand will not damage your phone’s battery. Modern smartphones have built-in charging management chips that regulate how power is received. The key is to stick to well-known brands that include overcharge and temperature protection, rather than buying very cheap unbranded models.
What is the best portable charger for the money in the UK?
For most people in 2026, the Anker 737 Power Bank at around £89 offers the best combination of capacity, speed, and reliability. If budget is a priority, the Belkin BoostCharge 10K at around £22 is outstanding value and widely available from UK retailers including Amazon, Currys, and John Lewis.
How long does a portable charger last before it needs replacing?
A well-made power bank from a quality brand will typically retain around 80% of its original capacity after 500 full charge cycles — equivalent to roughly three to five years of regular use for most people. Storing your power bank somewhere cool and avoiding fully draining it regularly will help extend its lifespan further.
