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.

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.
