10 Best Portable Chargers

The INIU Smallest 20000mAh Power Bank offers a strong balance between power and portability, making it a solid choice for travelers or anyone needing reliable backup power on the go. Its 20000mAh capacity is enough to fully charge most smartphones about four times, which is impressive for a device that fits comfortably in your pocket at just 310 grams and compact dimensions. A standout feature is its true 22.5W fast charging capability, which can charge popular phones like the Samsung S25 to 70% or the iPhone 16 to 60% in about 25 minutes, saving you time when you’re in a hurry.

The power bank includes two USB-C ports and one USB-A port, allowing you to charge multiple devices simultaneously, including smartphones, tablets, and even some low-power camping gadgets. It also supports pass-through charging, so you can charge the power bank itself while charging other devices. The built-in detachable USB-C cable, which doubles as a durable nylon lanyard, is a nice touch that helps reduce the number of cables you need to carry. Additionally, the device is TSA-approved, making it convenient for air travel, and the built-in flashlight adds practical value for emergencies or outdoor use.

On the downside, while the power bank is compact, it is slightly thicker than some ultra-slim models, and the 22.5W output, though fast, is not the fastest on the market for high-end devices that support higher wattage charging. Also, Apple users might find the built-in cable less directly compatible, relying on extra ports instead. The 3-year warranty and solid safety protections help ensure durability and peace of mind. This charger is a reliable, travel-friendly option for people who want a good mix of capacity, speed, and handy features without bulk.

The UGREEN Magsafe Power Bank offers a solid 10,000mAh capacity, which is enough to recharge most smartphones about one to two times, making it practical for daily use or short trips. It stands out for its magnetic wireless charging that supports up to 15W fast charging, especially convenient for iPhone users since it aligns securely and avoids slipping during use. You can also charge two devices at once using its 20W USB-C port, which is handy if you have multiple gadgets.

Its slim and lightweight design (only 222 grams and just over 1cm thick) makes it easy to carry in a pocket or bag without feeling bulky. The charger also supports fast recharging of itself at 20W, so it won’t take too long to refill the power bank. Safety is well-covered with protections against overcurrent, voltage, short-circuits, and overheating, plus it meets airline regulations for travel.

On the downside, while 15W wireless charging is fast for wireless standards, it’s slower than some top wired chargers, and the 10,000mAh capacity might be limiting if you need to charge larger devices or multiple times on a longer trip. Also, the magnetic feature is designed mainly for newer iPhones, so users with other phones might not benefit from this convenience. In summary, this power bank is a great fit if you want a portable, reliable charger with wireless Magsafe compatibility for iPhones and decent fast charging on the go.

The Anker 737 Power Bank stands out with its large 24,000mAh capacity, capable of charging phones like the iPhone 13 nearly five times or topping up larger devices such as an iPad Pro. It offers an impressive 140W output across three USB-C ports, meaning it can quickly charge laptops, tablets, and smartphones, making it especially useful for users who need power on the go for multiple devices. The charger also supports fast input charging, so the power bank itself refills relatively quickly.

At about 630 grams and a size of roughly 15.6 x 5.5 x 5 cm, it’s a bit heavier and bulkier compared to smaller portable chargers, which might be a consideration if you want something ultra-light for pocket carry. One helpful feature is the smart digital display that shows charging power and estimated recharge time, making it easy to keep track of the battery level and charging status. However, it does not support wireless charging, so if you prefer placing your phone on a pad instead of cables, this might be a downside.

The Anker 737’s strong build quality, extensive device compatibility, and fast charging make it a reliable choice for travelers or professionals needing power for laptops and multiple gadgets. If lightness or wireless charging is a priority, you might want to explore other options.
