What Is a Power Bank?

A power bank (also called a portable charger, battery pack, or external battery) is a rechargeable lithium battery that stores energy so you can charge your phone, tablet, laptop, earbuds, or any USB device on the go — no wall outlet needed. In 2026, the best power bank chargers offer USB-C Power Delivery (PD) fast charging, airline-safe capacities, and enough output to charge laptops.

Our Verdict

The Anker PowerCore 10000 PD is the world's most popular power bank for a reason. It's compact, reliable, and genuinely fast-charges modern phones. At 195g it disappears into a jacket pocket. If you want a no-nonsense daily power bank from the most trusted brand in portable charging, this is it.

The build quality is premium with an aluminium chassis, and the digital display is razor-sharp. If you want a laptop power bank that slips into a laptop sleeve, the Blade is unbeatable.

  • 20W USB-C wired output as backup
  • Kickstand built-in for propped-up viewing
  • LED ring shows charge level
  • Works with all MagSafe iPhone cases

Our Verdict

The Anker MagGo is the best MagSafe power bank for iPhone users. It snaps onto the back of your iPhone and charges wirelessly — no cables needed. The built-in kickstand is genuinely useful for video calls and watching content. At 133g and 5,000mAh, it's designed for a quick top-up rather than a full charge, but that's exactly what most iPhone users need.

  • 20W USB-C pass-through charging
  • Official Made for MagSafe certification
  • Slim design with premium finish
  • Charge phone + power bank simultaneously

Our Verdict

The Belkin BoostCharge 10K is the premium MagSafe power bank choice. At 10,000mAh it offers double the capacity of most magnetic banks, and 15W MagSafe is the fastest wireless charging speed available for iPhone. It's Apple's recommended Belkin power bank for MagSafe. The higher price is justified by the larger capacity and official certification.

MagSafe Power Banks — Wireless Charging on the Go

A MagSafe power bank snaps onto the back of your iPhone and charges wirelessly — no cables needed. Here's what you need to know.

MagSafe Power Bank Pros

  • Cable-free — just snap on and charge
  • Ultra-portable — most weigh under 200g
  • Works through MagSafe cases
  • Built-in kickstand on premium models
  • Also works wired via USB-C
  • Perfect for quick top-ups on the go

Things to Consider

  • —Slower than wired (7.5–15W vs 20–30W)
  • —Smaller capacity (typically 5,000–10,000mAh)
  • —More expensive per mAh than wired banks
  • —Only works wirelessly with iPhone 12+
  • —Generates more heat than wired charging
  • —Some thick cases block magnetic connection

Our MagSafe Recommendation

For most iPhone users, the Anker MagGo 5000mAh (£30–35) is the best balance of price, weight, and features. If you need more capacity, the Belkin BoostCharge 10K MagSafe (£40–50) doubles the battery with 15W MagSafe (vs 7.5W on most competitors). Both are reviewed in detail above. For wireless charging pads at home, see our Anker Wireless Charger Guide.

Power Bank Charging Tips & Best Practices

Get the most from your power bank charger with these expert tips.

Always Use USB-C PD Input

USB-C PD input (18W+) recharges your power bank 3–4× faster than Micro-USB. A 10,000mAh bank charges in 3 hours via USB-C vs 8+ hours via Micro-USB. This is the single most important spec to check.

Charge Overnight Before Travel

Always charge your power bank fully the night before a trip. Airport security may ask you to power on electronic devices — a dead power bank could be confiscated.

Look for CE/UKCA Certification

Only buy power banks with CE and UKCA markings for UK use. Avoid unbranded or suspiciously cheap power banks — they may lack overcurrent, overvoltage, and temperature protection.

Avoid Extreme Temperatures

Lithium batteries degrade faster in heat. Don't leave your power bank in direct sunlight, on a car dashboard, or near heat sources. Ideal operating temperature is 0–35°C.

Check Real-World Capacity

Advertised capacity (e.g., 10,000mAh) is the battery cell rating. Real-world output is ~65–70% due to voltage conversion. A 10,000mAh bank delivers about 6,500–7,000mAh to your phone.

MagSafe Is Slower but Convenient

MagSafe wireless charging (7.5–15W) is slower than wired USB-C (20–30W). Choose MagSafe for convenience when you're not in a rush, and USB-C wired when you need speed.

Power Bank Airline Rules (UK & International)

Flying with a power bank? Here are the rules every UK traveller needs to know:

Under 100Wh (≈ 27,000mAh)

✅ Allowed in hand luggage — no approval needed

100–160Wh (27,000–43,000mAh)

⚠️ Airline approval required — contact before flying

Over 160Wh (43,000mAh+)

❌ Banned on all commercial flights

Checked luggage

❌ Power banks are NEVER allowed in checked bags

Quick maths: Wh = mAh × V ÷ 1000. A 20,000mAh bank at 3.7V = 74Wh (well under 100Wh). A 25,000mAh bank at 3.6V = 90Wh (still under the limit). Both our UGREEN 25,000mAh and UGREEN 20,000mAh are airline approved.

Power Bank FAQs

Common questions about power banks, capacity, airline rules, MagSafe, and charging.

What is the best power bank to buy in 2026?
The best power bank depends on your needs. For everyday phone charging, a 10,000mAh power bank with 20W USB-C PD (like the Anker PowerCore 10K) is ideal — compact, affordable, and fast. For laptop charging, the UGREEN 25000mAh 145W is our top pick with 140W output that charges MacBook Pros. For iPhone users, a MagSafe power bank offers wireless convenience. For travel, a 20,000mAh 65W bank covers phones, tablets, and laptops while staying airline-approved.
Is Anker the best power bank brand?
Anker is one of the best power bank brands, known for reliability, safety certifications, and excellent customer support. Their PowerCore range consistently tops reviews. However, UGREEN and Baseus now offer serious competition — UGREEN's Nexode power banks deliver higher wattage (130–145W) at competitive prices, while Baseus offers innovative features like built-in cables and digital displays. The "best" brand depends on your specific needs and budget.
Can I charge a power bank with another power bank?
Yes, you can charge a power bank with another power bank — this is called "daisy chaining." Connect a USB-C cable between the two power banks. The one with passthrough charging or higher output will typically charge the other. However, this is inefficient (you'll lose 10–15% energy in the transfer) and slow. It's useful in emergencies but not recommended as a regular charging method. It's much better to charge your power bank from a wall charger.
What size power bank do I need for my phone?
Most smartphones have 3,000–5,000mAh batteries. A 5,000mAh power bank gives about 1 full charge, 10,000mAh gives 2–3 charges, and 20,000mAh gives 4–6 charges. For daily commuters, 10,000mAh is the sweet spot — it's compact enough for a pocket and gives a full day of backup power. For travellers or heavy phone users, 20,000mAh ensures you'll never run out.
Are power banks allowed on planes?
Yes, but only in hand luggage — power banks are banned from checked baggage worldwide. Most airlines allow power banks up to 100Wh (approximately 27,000mAh at 3.7V) without approval. Power banks between 100–160Wh require airline approval. Banks over 160Wh are banned. A typical 20,000mAh power bank is 74Wh — well within limits. Always check your specific airline's policy before flying.
What is a MagSafe power bank?
A MagSafe power bank is a wireless power bank with built-in magnets that snaps onto the back of iPhone 12 and newer models (or any phone with a MagSafe-compatible case). It charges your phone wirelessly at up to 15W without any cable. The best MagSafe power banks also have a USB-C port for wired charging of non-MagSafe devices. Belkin, Anker, and UGREEN all make excellent MagSafe power banks ranging from 5,000–10,000mAh.
How long does a power bank take to charge?
Charging time depends on capacity and input speed. A 10,000mAh power bank takes about 2–3 hours with 18–20W USB-C PD input, or 6–8 hours with old 5W Micro-USB input. A 20,000mAh bank takes 4–5 hours via USB-C PD. The UGREEN 25000mAh 145W charges in just 2 hours with a 65W adapter thanks to its high-speed input. Always buy a power bank with USB-C PD input for dramatically faster recharging.
What is the difference between a power bank and a portable charger?
There is no difference — "power bank" and "portable charger" are the same thing. Both refer to a rechargeable battery pack you carry to charge your devices on the go. "Power bank" is the more common term globally and in the UK, while "portable charger" is sometimes used in marketing. Some people also call them "battery packs" or "external batteries." They all mean the same device.
