10 Best Portable Charger 2025 in the United States

The INIU Portable Charger is a slim and lightweight power bank with a capacity of 10000mAh. This means it can charge devices like the iPhone 8 around 3.6 times or the Samsung S22 about 1.8 times before needing a recharge itself. One of its standout features is its slim design, being only 0.5 inches thick, making it very portable and easy to carry in a pocket or bag.

It's equipped with both USB-C and USB-A ports, which is relatively rare (only 5% of power banks have USB-C input and output). This makes it versatile for charging different devices using USB-C cables directly. The 3A high-speed charging ensures that your devices can be charged quickly, up to 78% in just one hour for an iPhone. Safety is a priority with its 15-layer SmartProtect system, which prevents overheating and battery damage.

The package includes a USB-C cable, a travel pouch, and a user manual, along with a 3-year warranty and lifetime technical support from INIU. However, it's worth noting that while having a high capacity and fast charging, the power bank doesn't support wireless charging, which some users might find limiting. Additionally, the power bank includes convenient features like indicator lights and a built-in flashlight, making it practical for travel and everyday use.

The Anker 325 Power Bank (PowerCore Essential 20K) is a strong choice if you need a reliable portable charger with a large capacity. Its 20,000mAh battery can recharge popular smartphones like the iPhone 15 about 3.6 times, which is enough for several days without access to a wall plug. It offers multiple ports: two USB-A, one USB-C that supports fast 15W charging both for input and output, and a Micro USB for flexible recharging options. This means you can charge two devices at once, which is handy when you have multiple gadgets. The power bank also includes Anker’s PowerIQ and VoltageBoost technology to ensure your devices charge safely and efficiently, even those that need very low power like wireless earbuds.

Its size and weight are reasonable for its capacity—about 6.2 x 2.9 x 0.8 inches and just over 13 ounces—making it portable but not pocket-friendly for all users. One downside is the charging time: it takes around 9 hours to fully recharge the power bank with a 15W charger or higher, so it’s not ideal if you want very quick turnaround. Also, it uses two internal batteries, which is common but means it is a bit bulkier than smaller capacity models.

This power bank is suitable for anyone looking for a dependable, high-capacity charger to keep multiple devices powered during travel or long days out, as long as you’re okay with its size and moderate recharge time.

The Anker 621 Magnetic Portable Charger (MagGo) offers a convenient solution for iPhone users who need a portable power source. Its 5,000mAh capacity is suitable for providing a decent charge to your phone, though it may not fully charge larger devices or multiple times without needing a recharge. The wireless charging feature is Magsafe-compatible, making it particularly useful for iPhone 12 through iPhone 16 models.

The strong magnetic attachment ensures that it stays firmly on the back of your phone, which is great for hands-free use like taking selfies or making calls. The included USB-C to USB-C cable allows for wired charging options if needed, enhancing its versatility. One notable advantage is its compact size and lightweight design, making it easy to carry in pockets, purses, or bags without adding much bulk.

However, some users might notice slight heating during use, which is a common occurrence with wireless chargers. Its portability and strong attachment make it a reliable companion for iPhone users looking for a quick and easy charging solution on the go. Additionally, the product comes with a worry-free 24-month warranty. If you're an iPhone user needing a portable and efficient charging solution, this could be a good option for you.
