Quick Summary
- Best Overall: Anker 737 Power Bank (PowerCore 26K) — superb capacity, fast charging, and rock-solid build quality

Running out of battery on your iPhone when you need it most is genuinely frustrating. Whether you’re commuting across London, exploring a festival site, or travelling abroad, a reliable portable charger is no longer a luxury — it’s an essential piece of kit. With so many power banks on the market in 2026, choosing the right one for your iPhone can feel overwhelming. We’ve tested and researched the top options across every budget, from wallet-friendly picks under £20 to premium power banks that charge multiple devices simultaneously. Here’s everything you need to know to find the best portable charger for your iPhone.
What to Look For
- Capacity (mAh): The higher the milliamp-hour rating, the more charges you’ll get. An iPhone 16 has a roughly 3,560mAh battery, so a 10,000mAh bank gives you around two and a half full charges — ideal for a long day out.
- Charging Speed: Look for Power Delivery (PD) or USB-C 20W+ output to take advantage of iPhone’s fast-charging capability. Slower 5W chargers can take hours to top up a modern iPhone.
- MagSafe & Wireless Compatibility: If you own an iPhone 12 or later, a MagSafe-compatible power bank snaps magnetically onto the back of your phone for cord-free convenience — a genuine game-changer for on-the-go use.
- Size & Weight: Higher capacity usually means heavier. Consider where you’ll use it most — a slim 5,000mAh bank slips into a jacket pocket, while a 26,000mAh brick is better suited to a rucksack or travel bag.

Frequently Asked Questions
How many mAh do I need to fully charge an iPhone?
An iPhone 16 has a battery capacity of approximately 3,560mAh, so a 10,000mAh power bank can give you around two to two-and-a-half full charges after accounting for energy conversion losses. For multiple full charges or multi-day trips, opt for a 20,000mAh or 26,800mAh model.
Can I take a portable charger on a plane?
Yes, but most airlines and the UK Civil Aviation Authority (CAA) require power banks to be carried in hand luggage only — never in checked baggage. Most airlines permit power banks up to 100Wh (roughly 27,000mAh at 3.7V) without special permission, so check your specific airline’s policy before travelling.
Is MagSafe charging on a power bank worth it?
If you own an iPhone 12 or later, MagSafe-compatible power banks are genuinely convenient — they snap onto the back of your phone magnetically, eliminating cable fumbling. The wireless charging speed tops out at 15W, which is perfectly adequate for top-ups on the go, though wired USB-C remains faster for a full charge from flat.
What charging cable do I need with a portable charger for my iPhone?
Modern iPhones (iPhone 15 and 16) use a USB-C cable, so you’ll need a USB-C to USB-C cable to take full advantage of fast charging. If you own an older iPhone 14 or below with a Lightning port, you’ll need a USB-C to Lightning cable. Always use an Apple-certified or MFi-certified cable for reliable performance.
How long does it take to recharge a portable charger itself?
This depends heavily on capacity and input speed. A 10,000mAh bank with an 18W USB-C input will typically recharge in around two to three hours, while a 26,800mAh model like the Anker 737 can take four to six hours via its 65W input. Always plug your power bank in overnight to ensure it’s fully ready for the next day.
