10 Best Portable Battery Chargers For Cell Phones 2025 in the United States

This portable charger offers a solid 12,000mAh capacity, which is enough to recharge most smartphones 2 to 3 times, making it a good choice for daily use or short trips. It supports fast charging with up to 22.5W output through multiple ports, including USB-A and USB-C, and even has built-in cables, so you won’t have to carry extra cords. That’s a handy feature for travel or on-the-go charging. The charger itself can be recharged either through its built-in wall plug or a USB-C port, allowing flexibility and faster recharging—fully charging in about 4 to 5 hours. Its compact size and lightweight design make it easy to carry in a pocket or small bag. A digital LED display shows the remaining battery level, which helps you monitor power without any guesswork. Safety features like protection against overcharging and overheating add peace of mind during use.

On the downside, while the capacity is decent for everyday use, it might fall short for longer trips without access to charging, especially if you want to charge multiple larger devices. Also, although it has built-in cables, the selection and length might not fit all device types or charging scenarios. The output power, while fast, is not among the highest available on the market, so some very power-hungry devices may charge a bit slower compared to more powerful models.

This power bank is well-suited for travelers and everyday users who want convenience, portability, and reliable charging without too much bulk or complexity.

The Anker PowerCore 10K is a compact and travel-friendly portable charger with a 10,000mAh capacity, enough to charge an iPhone 12 about two times or a Galaxy S20 about one and a half times. It’s quite slim and lightweight, making it easy to carry in a bag or even a pocket. The charger includes two ports: one USB-C input (which cannot output power) and one USB-A output port. This means you can charge the power bank itself via USB-C but can only charge your devices through the USB-A port.

It delivers up to 3 amps of output power, supporting fast charging up to 12W for compatible devices, thanks to Anker’s PowerIQ technology that adjusts charging speed based on the device. This makes it a solid choice for quickly topping up phones and smaller gadgets. The inclusion of a trickle-charging mode is helpful for safely charging low-power devices like Bluetooth earbuds. On the downside, the single output port limits simultaneous device charging, and it lacks USB-C output which is becoming more common for faster charging and wider compatibility.

The charger is built tough with scratch-resistant materials and includes multiple safety features like overcharge and short circuit protection, adding peace of mind during use. It comes with a micro USB cable for charging the power bank, but you’ll need to provide your own USB-C or Lightning cables for your devices. Weighing just 7.5 ounces and measuring under 6 inches long, it strikes a good balance between power and portability. This portable charger is well suited for everyday users who want a reliable, easy-to-carry backup battery for their phone or tablet, though it may not be ideal if you need to charge multiple devices simultaneously or prefer the convenience of USB-C output.

The RGVOTA 38800mAh Portable Charger is a robust power bank that ensures your phone remains charged throughout the day. Its ultra-large capacity, 38800mAh, is a significant advantage, making it suitable for users who need to charge their devices multiple times or have several devices. With 4 USB output ports and a dual input option, it caters to various charging needs, allowing simultaneous charging of multiple devices. The USB-C port is particularly beneficial for users with newer devices that utilize USB-C technology.

The digital LED display is a user-friendly feature that keeps you informed about the charger’s status. The built-in intelligent chip offers protection against overcharging, excessive currents, short circuits, and overheating, ensuring the safety of your devices. However, the charger is relatively heavy at 15.8 ounces and large in size (6.3 x 0.98 x 3.94 inches), which might not be ideal for users seeking a compact and lightweight portable charger.

Additionally, while it supports fast charging, the input speed of 5V/2.1A may not be as quick as some other models on the market. Despite these drawbacks, the RGVOTA Portable Charger is a solid choice for users looking for a high-capacity power bank with multiple output options and reliable safety features.
