Power Banks

Yes, but choose a power bank with enough output and the right charging protocol for your laptop. Many USB-C laptops need approximately 45–100W or more, while smaller phone-focused banks may be insufficient. Check your laptop's charging requirements and cable rating and choose Anker power banks offering 100W or 140W from an individual USB-C port to ensure efficient laptop charging.

A good-quality power bank often lasts around two to four years or 300 to 500 full charge cycles with regular care, although battery capacity gradually declines with repeated charging. On one full charge, a 10,000mAh power bank may recharge a typical smartphone roughly once or twice, while a 20,000mAh model may manage several charges. Actual results depend on the device and conversion losses.

Yes, if the power bank supports pass-through charging, which lets it recharge while powering another device. For example, the Anker Laptop Power Bank (25K, 165W, Built-In and Retractable Cables) supports this function with a 20W or higher charger and adequate incoming power. Other power banks without this feature may disable output while recharging. Check the instructions and avoid trapping heat during simultaneous charging.

Start by checking your phone or laptop's charging connector and required wattage. Then choose a capacity that fits your routine: 5,000–10,000mAh for lighter use or 20,000mAh and above for longer trips. Compare weight, built-in cables, ports and safety protections. For flights, check the battery's watt-hour rating and your airline's rules.

A 10,000mAh power bank is usually lighter and easier to carry, making it a practical choice for daily commuting and occasional phone charging. A 20,000mAh power bank stores roughly twice the energy and is better for holidays or charging several devices, but it is bulkier. Neither delivers its full rated capacity to your phone because charging involves energy losses.

For everyday phone use, 5,000–10,000mAh is often a convenient range. Around 10,000–20,000mAh balances portability with more charging reserve, while 20,000–27,000mAh can suit long trips and compatible laptops. Consider physical size and weight alongside capacity. If you fly, check watt-hours rather than relying on the mAh figure alone.

Usually, yes. A typical 20,000mAh lithium-ion power bank rated at 3.7V contains about 74Wh, below the standard 100Wh limit. Under current UK CAA rules, carry power banks in cabin baggage, not checked luggage, and bring no more than two. Do not recharge them aboard, and check your airline's restrictions on in-flight use.

Stop using or charging a swollen power bank immediately, and disconnect it only if safe. Never puncture, squeeze or attempt to repair it. Keep it away from heat and flammable materials, and contact your local council or an approved battery recycler for safe handling. If it starts smoking or burning, move away and call emergency services.

The best power bank depends on your charging needs. For everyday use, the Anker Nano Power Bank (10K, 45W) combines a compact design, fast USB-C charging and a built-in 2.3 ft (70 cm) retractable cable, ideal for charging your iPhone 18 Pro on the move. For laptops and business travel, the Anker Laptop Power Bank (25K, 165W) offers 25,000mAh capacity, two built-in USB-C cables and up to 100W output from a single USB-C port.
