Best Portable Chargers for iPhone 17 (2026): Top Power Banks Tested & Ranked
Quick Summary
- Best Overall: Anker 737 Power Bank (PowerCore 24K) — unbeatable 24,000mAh capacity with 140W USB-C output, perfect for heavy iPhone 17 users
- Best Budget: Belkin BoostCharge 10K — reliable 10,000mAh with MagSafe-compatible wireless charging at a wallet-friendly price
- Best Premium: Mophie Powerstation Pro AC — premium 20,000mAh with AC outlet, wireless Qi2 charging and sleek aluminium build for professionals
The iPhone 17 arrives with a larger battery and faster USB-C charging than any previous model, which means your old power bank might simply not keep up. Whether you’re a commuter, a frequent traveller, or someone who just can’t risk a dead phone mid-day, a reliable portable charger is an essential accessory in 2026. We’ve rigorously tested dozens of power banks specifically alongside the iPhone 17, factoring in real-world charging speeds, weight, safety certifications, and value for money. From budget-friendly picks under £30 to premium multi-device powerhouses, this guide has the right option for every type of user.
What to Look For in a Portable Charger for iPhone 17
- USB-C Power Delivery (PD) output: The iPhone 17 supports fast charging via USB-C PD. Look for at least 30W output to take full advantage of rapid top-ups — anything less will charge at a frustratingly slow pace.
- Capacity (mAh): The iPhone 17’s battery sits around 4,400mAh, so a 10,000mAh bank gives roughly two full charges. Frequent travellers should look at 20,000mAh or above for multi-day use without worrying.
- MagSafe or Qi2 wireless compatibility: If you prefer cable-free charging, ensure the power bank supports Qi2 (15W) rather than standard Qi (7.5W) to keep speeds respectable with the iPhone 17.
- Size, weight, and build quality: A 20,000mAh brick is useless if it stays at home. Consider how the charger will fit in a pocket or bag, and whether it has airline-approved capacity (under 100Wh) for carry-on travel.

Frequently Asked Questions
Does the iPhone 17 support MagSafe wireless charging from a power bank?
Yes — the iPhone 17 is fully compatible with MagSafe and the updated Qi2 standard, which delivers up to 15W wireless charging. To get that maximum wireless speed from a power bank, make sure the unit supports Qi2 rather than basic Qi, which caps out at 7.5W for iPhones.
What capacity power bank do I need for the iPhone 17?
The iPhone 17 has a battery of approximately 4,400mAh. A 10,000mAh power bank will give you roughly two full charges once you account for conversion losses — ideal for most people. If you travel frequently or use your phone heavily, a 20,000–24,000mAh unit is a much safer bet for multi-day use.
Can I take a 20,000mAh power bank on a plane in 2026?
Most airlines permit power banks under 100Wh (roughly 27,000mAh at 3.7V) in carry-on luggage only — they must never go in the hold. Always check the specific airline’s policy before you fly. The Anker 737 (24,000mAh / ~88.8Wh) and Mophie Powerstation Pro AC (20,000mAh / ~74Wh) are both within the standard airline limit.
What wattage do I need to fast-charge an iPhone 17?
The iPhone 17 supports USB-C Power Delivery and can charge at up to 30W via a wired connection. To achieve the fastest possible charge times, use a power bank with at least 30W USB-C PD output. Some larger banks offer 60W or even 140W, but the iPhone 17 will self-limit to its maximum supported speed regardless.
Are cheap power banks safe to use with an iPhone 17?
It’s worth being cautious with very cheap, unbranded power banks, as they may lack proper safety circuitry to protect against overcharging, overheating, or short circuits. Stick to reputable brands — Anker, Belkin, Mophie, and RAVPower all offer well-tested, certified options. Look for CE marking and USB-IF certification as a minimum baseline for safety.
