10 Best Compact Portable Chargers 2025 in the United States

The INIU Portable Charger stands out in the compact and portable category primarily for its 10000mAh capacity packed into a remarkably slim and lightweight design. Measuring just 0.5 inches in thickness and weighing 8.8 ounces, it is easy to carry around, making it ideal for travel enthusiasts who need a portable power solution for a weekend getaway.

One of its standout features is the dual USB-C IN&OUT port, which is relatively rare and offers versatile charging options for a variety of devices, from iPhones to Samsung phones and even iPads. The 3A high-speed charging capability ensures that your devices charge quickly, with claims of fueling an iPhone up to 78% in just one hour. Safety is a strong focus for this charger, boasting a 15-layer SmartProtect system that minimizes risks like overheating and battery damage.

Additionally, the built-in flashlight can be a handy tool in emergencies. However, despite its many strengths, some users might find the included 0.3M/1ft USB-A to USB-C cable a bit short for certain situations. This power bank is best suited for those needing a reliable, high-capacity, and ultra-portable charging solution with added safety features.

The Anker Nano 3-in-1 Portable iPhone Charger is designed for those who need a compact and versatile charging solution. With a 10,000mAh capacity, it can charge an iPhone 15 Pro nearly twice or a Samsung S23 almost twice on a single charge. Its dimensions (4.25 x 2.01 x 1.22 inches) and weight (8.82 oz) make it highly portable, fitting easily into most bags and pockets.

An added convenience is the built-in USB-C cable and a foldable wall plug, eliminating the need for extra cables and adapters while traveling. This charger also supports fast charging, providing up to 30W output, which can charge an iPhone 15 Pro from 0 to 50% in just 25 minutes. This is advantageous for those who need quick power boosts throughout the day. Additionally, it can charge two devices simultaneously, increasing its practicality for users with multiple gadgets.

However, because it only includes USB-C ports, users with devices requiring different input types may need additional adapters. The build quality is robust, ensuring durability for regular use. Included with the product is an 18-month warranty, and support from Anker's customer service. This charger is particularly suitable for frequent travelers and those who prioritize convenience and efficiency in keeping their devices charged.

The Charmast Portable Charger boasts a 10,000mAh battery capacity, which is sufficient to power a variety of devices throughout the day. It can provide 1.6 full charges for an iPhone 13 and one full charge for a Samsung S22 Ultra. This makes it a reliable option for travelers or anyone who needs consistent access to their phone without worrying about running out of battery life. Its slim and compact design (5.95” x 2.76” x 0.72” and weighing about 8 ounces) fits comfortably in the palm or pocket, making it highly portable and convenient to carry around.

The built-in cables and wall plug are particularly useful features, eliminating the need to carry extra cords and chargers, and enhancing its travel-friendly aspect. The LCD display is a handy addition, showing the remaining battery visually, so you’re always aware of how much power you have left. The pass-through charging technology allows simultaneous charging of the power bank and your device, ensuring both are ready to go when you wake up. However, the maximum output under this function is only 1A, which is relatively slow.

The charger includes safety features like overcharge protection, which is essential for preventing damage to your devices. In terms of build quality, the product seems durable, and the 24-month support along with 7-day/24-hour customer service offers additional peace of mind. The Charmast Portable Charger is packed with features and offers decent performance, although the key drawback is the slower charging speed during pass-through charging. It is a versatile and practical power bank, especially suited for travelers and those who need a reliable portable charging solution for various devices.
