10 Best Battery Operated Chargers 2025 in the United States

The Belkin Portable Charger offers a solid 10,000 mAh battery capacity, which is enough to provide up to 31 additional hours of power for an iPhone, making it suitable for long days or trips. This charger is equipped with integrated Lightning and USB-C cables, offering convenience as an all-in-one charging solution for various devices like iPhone, Galaxy, and other USB-C compatible devices. With a 23W total output, it can charge two devices simultaneously, ensuring fast and efficient power delivery on the go.

The pass-through charging feature is particularly useful, allowing you to charge your device while the power bank itself is recharging, saving time with dual charging capabilities. The LED indicator light helps you monitor the power bank’s status, so you know when it's time to recharge it. However, its weight of 10.2 ounces and dimensions of 6 x 2.5 x 1 inches might be slightly cumbersome for some users who prefer lighter and more compact options. Additionally, while the charging cables are integrated for convenience, they limit flexibility in terms of swapping out cables if needed.

Ideal for travelers or individuals who need reliable power on the go, the Belkin Portable Charger balances convenience and performance effectively.

The Mophie Powerstation Core offers a large 20,000mAh battery, which means it can recharge an average smartphone up to four times before needing its own recharge. This makes it a solid choice if you need extended power during long days or travel. It supports fast charging with an 18W USB-C Power Delivery port, allowing your device to reach about 50% battery in just 30 minutes, which is convenient when you’re in a hurry.

The charger includes three ports — one USB-C and two USB-A — so you can charge multiple devices at once. However, the total shared output across all ports is 15W, so charging multiple devices simultaneously might be slower than using just one port. Weighing about 15 ounces and measuring roughly 6 by 3 by 1 inch, it’s reasonably portable but not the smallest option if you prefer super-compact chargers.

On the plus side, it’s sustainably made with recycled plastics, which is a nice bonus if you’re environmentally conscious. It also features LED indicator lights to show the battery level clearly. While it’s not the fastest charger on the market, and the shared output limits simultaneous charging speed, this Mophie model balances capacity, fast charging, and versatility well, making it a great pick for those who need reliable, multiple-device charging on the go without breaking the bank.

The mophie Powerstation XL is a solid choice if you need a reliable power bank with a large battery. Its 20,000 mAh capacity means it can charge your phone multiple times before needing a recharge itself, which is great for travel or long days out. It has three ports in total: two USB-A ports and one 20W USB-C port that supports fast charging. This USB-C port is especially helpful because it can quickly charge your devices and also recharge the power bank itself.

You can even charge three devices at once, although the total output shared among them is between 15W and 20W, so charging speed might slow down when using all ports simultaneously. The device is fairly compact and lightweight at just over 1.2 pounds, making it easy to carry in a bag without adding much bulk. The fabric finish helps protect it from scratches, and the LED lights give a clear indication of how much power remains. One nice extra is that it comes with a USB-C to USB-C cable, so you don’t have to buy that separately. Plus, it’s made with some recycled materials, which is a bonus if you care about sustainability.

On the downside, while the fast charging is useful, the total output when charging multiple devices isn’t very high compared to some other models, so it might not be the best choice if you want to charge several power-hungry devices quickly at the same time. Also, it lacks an on/off button, so it starts charging immediately when plugged in, which may drain the battery if left connected unnecessarily. This power bank suits travelers and everyday users who want a dependable and easy-to-use portable charger with good capacity and fast charging for at least one device.
