Its slim design, measuring only 0.5 inches thick, and lightweight body at 8.8 ounces, make it highly portable and convenient for travel enthusiasts.

The charger offers three ports, including the rare USB-C IN&OUT port, which allows users to charge their devices directly with USB-C cables—a feature only 5% of similar products have. This flexibility is a significant advantage for users with newer devices that leverage USB-C for faster charging and data transfer. The 3A output ensures high-speed charging, capable of boosting an iPhone's battery by up to 78% in just an hour, distinguishing it from slower 2.1A chargers.

Furthermore, its 15-layer SmartProtect system is designed to prevent overheating and battery damage, ensuring safe and reliable charging. Additional features such as the built-in flashlight can be handy in emergencies. The charger may not be suitable for users needing higher capacity power banks for longer trips or multiple devices. The INIU Portable Charger is a great choice for those seeking a lightweight, safe, and efficient charging solution with versatile connectivity options.

The UGREEN Power Bank 25,000mAh 145W is a high-capacity, multi-functional portable charger designed to meet the needs of users with various devices, including laptops, tablets, and smartphones.

The massive 25,000mAh capacity ensures multiple charges for your devices, which is particularly useful for long trips or for users with high power demands.

It can fully recharge laptops up to 1.3 times and mobile devices up to 5.2 times, which is impressive for a portable charger.

The compact design is a plus, making it easy to carry around despite its high capacity. The digital display is a useful feature that shows the remaining battery life, keeping you informed on the go.

With three ports (two USB-C and one USB-A), it offers flexibility in charging multiple devices simultaneously. The power bank's wide compatibility ensures it works with a range of devices from laptops to smartphones and gaming consoles. The high output power and large capacity could result in a heavier weight compared to smaller capacity power banks, which might be a consideration for users prioritizing portability.

The Belkin Portable Charger offers a substantial 10,000mAh capacity, providing up to 31 additional hours of power for your iPhone, making it a solid choice for long days or trips. The integrated Lightning and USB-C cables simplify your life by eliminating the need to carry extra cables, and its 23W output allows you to charge two devices simultaneously. This is particularly useful for users who need to keep multiple devices powered up throughout the day. The pass-through charging feature is handy, letting you charge your phone while the power bank itself is recharging.

An LED indicator helps keep track of the charge level, ensuring you know when it’s time to recharge the power bank itself. The compact size (6 x 2.5 x 1 inches) and weight (10.2 ounces) make it relatively portable, although it might feel a bit bulky for some users. It's not the lightest option out there, but the built-in cables and reliable performance could justify the size and weight for many. If you have an older device that doesn’t support USB-C, you might find this power bank less convenient.
