10 Best Power Banks

The Anker PowerCore Essential 20K is a solid choice if you need a reliable power bank with a large capacity. Its 20,000mAh battery can charge most modern smartphones multiple times—about 3.6 charges for an iPhone 15 and nearly 3 for a Samsung Galaxy S23 Ultra—making it convenient for trips or long days without access to power. The size is fairly portable, fitting into a bag easily, though it weighs around 380 grams, so it’s not the lightest option if you want something ultra-compact.

It has a USB-C port that supports both input and output at 15W, allowing for reasonably fast charging and the ability to charge two devices at once (one via USB-C and another via USB). The presence of both USB-C and Micro USB for recharging the power bank adds flexibility, although the full recharge time of about 9 hours might feel long if you need quick turnaround. Anker’s PowerIQ and VoltageBoost tech help deliver safe, optimized charging and include a trickle charge mode great for smaller devices like wireless earbuds. Compatibility covers a wide range of popular gadgets, including iPhones, Samsung phones, and AirPods.

The product comes with an 18-month warranty and decent customer support, which is reassuring. The charging speed of 15W is good but not the fastest compared to some newer power banks offering higher wattage. Also, while the design is functional, it’s not particularly compact or light for everyday pocket carry. For those wanting a dependable, high-capacity power bank that works well with most devices and can charge two gadgets simultaneously, this Anker model is a worthwhile option.

The INIU Power Bank is a compact and lightweight option for those needing a portable charging solution. With a capacity of 10,000mAh, it offers a decent amount of power for recharging devices. What stands out is its small size and light weight, being 30% smaller and 15% lighter than similar capacity power banks, making it highly portable. Its charging speed is impressive, equipped with a 45W fast-charging capability that can charge an iPhone 15 to 60% in just 25 minutes, which is useful for quick top-ups.

The power bank features multiple ports, including two USB-C ports and one USB-A port, allowing you to charge up to three devices simultaneously. This versatility can be handy in situations where multiple devices need power at once. The USB-C port can be used both for input and output, providing more flexibility compared to power banks that only allow for USB-C charging.

Compatibility is broad, supporting popular devices like iPhones, Samsung phones, and Google devices, which makes it a versatile choice for a range of users. Additional features such as indicator lights for battery status and the inclusion of a USB-A to USB-C cable add to its convenience.

However, for users who require more power for longer trips, the 10,000mAh capacity might be limiting compared to larger power banks. While it's great for short outings or daily use, it may not suffice for extended travel without frequent recharges. The product's delivery is restricted outside mainland UK, which could limit accessibility for some customers.

The INIU Power Bank is ideal for those seeking a reliable, fast-charging option in a small, easy-to-carry design, making it a travel-friendly choice for everyday use.

The Anker Laptop Power Bank offers a hefty 25,000mAh capacity, which is great for keeping laptops, smartphones, and tablets charged multiple times on long trips. Its standout feature is the three USB-C ports, all supporting up to 100W charging, letting you power multiple devices at full speed simultaneously—ideal for busy users with several gadgets. You can even charge four devices at once thanks to the built-in dual USB-C cables plus an extra USB-A port. Fast recharge is another plus; the power bank can reach 30% charge in just 20 minutes, so it won’t stay empty for long. Size-wise, it measures about 15.7 x 5.4 x 4.9 cm and weighs nearly 600 grams, making it a bit heavier and bulkier than smaller models, so it’s more suited to backpacks than pockets.

The two built-in retractable cables are handy for avoiding cable clutter, but their lengths might be limiting depending on your setup. This power bank is compatible with a wide range of modern devices, including the latest iPhone and Samsung models, making it versatile. It meets airline carry-on rules for batteries under 100Wh, which is useful if you travel by plane. The weight and size could be less convenient for everyday casual use, and it requires careful attention to cable lengths. For those needing a robust, high-capacity charger for multiple devices, especially laptops and phones, this power bank is a reliable choice.
