10 Best Lightest Portable Charger 2025 in the United States

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.

The INIU Portable Charger is a great pick if you want a light, compact power bank that doesn’t sacrifice capacity. With 10,000mAh, it offers enough power to recharge most smartphones about two times, which suits daily use or short trips. What really stands out is its weight—just 8.8 ounces—and smaller size thanks to a high-density battery cell, making it easy to carry in your pocket or bag. It supports fast charging with a 45W power delivery chip, letting you charge an iPhone 15 up to 60% in just 25 minutes, which is impressive for a charger this size.

Another nice feature is having two USB-C ports plus a USB-A port, so you can charge three devices at the same time—handy if you carry multiple gadgets. The build quality seems strong, using high-grade materials, and it includes safety features to protect your devices from overheating or short circuits. However, the 10,000mAh capacity, while good for portability, might be limiting if you need to charge larger devices like tablets multiple times. Also, its charging speed is fast but not the highest available on the market, especially compared to bigger power banks designed for laptops.

This charger is well suited for people who want a lightweight, reliable power bank mainly for smartphones and small devices, especially if portability and quick top-ups on the go are priorities.
