10 Best Lightest Portable Charger 2025 in the United States

The Anker 621 Magnetic Portable Charger (MagGo) is a great choice if you want a light and compact power bank, especially designed for iPhone users with MagSafe compatibility. With a 5,000mAh capacity, it provides a decent amount of power to recharge your phone once or top it up several times, making it convenient for daily use or short outings. It weighs only 5 ounces and has a slim profile, so it's easy to carry in your pocket or attach magnetically to the back of compatible iPhones without adding bulk.

The magnetic attachment is strong, which helps prevent it from falling off during use and makes wireless charging simple since you just snap it on without worrying about alignment. It also comes with a USB-C cable for wired charging, offering flexibility in how you charge your devices. While it focuses on portability, this charger does not have multiple output ports, so charging multiple devices at once isn’t an option. The charging speed is good for casual use but won’t match faster, larger power banks designed for quick refills.

The build quality is solid, and the device meets international safety standards, though it can get a bit warm during use, which is normal. If you’re looking for a portable, easy-to-use charger mainly for your iPhone and value convenience and light weight, this product fits well. However, if you need to charge multiple devices simultaneously or want longer battery life, you may want to consider larger options.

The Baseus Laptop Portable Charger is a slim and travel-friendly power bank ideal for business travelers or anyone needing reliable power on the go. With a high 20000mAh capacity, it can charge most 13 to 15-inch laptops up to 70% and provide several full charges for phones like the iPhone 16 Pro. Despite its strong capacity, it remains relatively light at about 16 ounces and compact with dimensions just over 5 inches square and under an inch thick, making it easy to carry in a laptop bag or briefcase without adding bulk.

It offers fast 100W USB-C Power Delivery charging, capable of charging a MacBook Pro to 50% in about 30 minutes. Multiple output ports, including two USB-C and two USB-A, ensure compatibility with a range of devices from laptops to phones and tablets. Safety is well covered through certified protections against overcharging, overheating, and short circuits, which adds peace of mind when using it with valuable devices. The built-in digital display helps monitor remaining power, a useful feature for managing charging needs during travel.

One downside is that while it’s slim and TSA-compliant, it’s not the absolute lightest power bank available, and its square shape might not fit as comfortably in smaller pockets. This charger is particularly suited for users who prioritize fast laptop charging and portability without compromising on power and safety.

This 12,000mAh portable charger strikes a good balance between capacity and portability, making it well-suited for anyone needing a lightweight but reliable power bank. At just 3.53 ounces and under an inch thick, it easily fits in your pocket or bag without adding bulk. The built-in AC wall plug and USB-C cable are excellent for convenience, letting you recharge the power bank quickly (4-5 hours) without carrying extra cords—ideal for travel.

It supports fast charging through three ports, including a USB-A and two USB-C options, delivering up to 22.5W power, so your phone or tablet charges swiftly. The LED display is handy for keeping track of remaining power, helping avoid surprises on the go. Safety features like protection against overcharging and overheating add peace of mind, especially for air travel.

While the 12,000mAh capacity provides roughly 2-3 full smartphone charges, it may fall short for power users who need multiple recharges or want to charge larger devices like laptops. Despite being slim and lightweight, it is not the absolute smallest or lightest charger available for those prioritizing extreme portability over capacity. This power bank delivers a thoughtful mix of fast charging, practical design, and safety for everyday use and travel, especially for users valuing built-in cables and a compact form without sacrificing moderate battery life.
