10 Best Lightest Portable Charger 2025 in the United States

The Anker MagGo Power Bank is a great choice if you want a lightweight and slim portable charger, especially for newer iPhones. Its 10,000mAh capacity is solid enough to nearly double your iPhone 15 Pro’s battery, fitting well in the lightest portable charger category without adding bulk thanks to its ultra-slim profile and 7-ounce weight. It offers both a 15W magnetic wireless charger designed specifically for iPhone 12 through 16 models and a 30W USB-C port for faster wired charging, giving you flexible options.

The metal frame and aerogel insulation help keep the device cool and durable, which is a nice touch for everyday use. However, if you have an Android phone or an older iPhone, the magnetic charging won’t work, and wireless charging speeds will be slower. Also, with only one USB-C port, it’s best for charging one device at a time if you want the fastest output.

This power bank is ideal for iPhone users who prioritize portability and magnetic convenience but may be less appealing if you need universal fast wireless charging or multiple outputs. Its safety features like overcharge protection and dust resistance add peace of mind on the go.

The Charmast 10000mAh Portable Charger is designed for those on the go, offering a significant capacity while maintaining a slim and lightweight design. Weighing just 0.55lb and measuring 5.68''x2.63''x0.69'', it is compact enough to carry around easily, similar to a lighter cell phone. One of its standout features is the built-in cables, which include 3 output cables and 1 input cable, eliminating the need to carry extra cables or adapters.

Additionally, it has 6 output ports and 3 input options, allowing you to charge up to 6 devices simultaneously, which is a big plus for multi-device users. The digital LED display is a handy feature for monitoring the remaining battery percentage, ensuring you are never caught off guard with a dead charger.

In terms of universal compatibility, it supports a wide range of popular devices, including various models from iPhone, Samsung, and Google Pixel series. The charging speed, while decent at 3A, may not be the fastest available on the market. The build quality appears solid, and safety features are implied though not explicitly detailed. For those seeking a combination of portability, convenience, and multi-device support, this charger is a strong contender.

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.
