10 Best Portable Battery Chargers 2025 in the United States

The Jackery Explorer 1000 v2 is a strong choice if you need a reliable portable power station for camping, RV trips, or emergency backup. It offers a large 1,070Wh battery capacity, enough to power appliances like fridges and AC units with its 1,500W continuous and 3,000W peak output. Despite this power, it remains relatively lightweight at about 24 pounds and has a compact design with a foldable handle, making it fairly easy to carry around.

One standout feature is its fast charging capability. Thanks to the Jackery App, you can charge it fully in about one hour if you enable emergency charging—otherwise, it takes around 1.7 hours, which helps protect battery life. Speaking of the battery, it uses a durable LiFePO4 (LFP) type that lasts more than 10 years with over 4,000 charge cycles, a big plus if you want long-term use. The Explorer 1000 v2 includes multiple output ports: three AC outlets with pure sine wave power (good for sensitive electronics), two USB-C ports (one with 100W fast charging), one USB-A, and a DC car port. This variety means you can charge several devices at once, from phones and laptops to small appliances.

Safety-wise, it uses advanced ChargeShield 2.0 technology, which manages charging to keep things safe and efficient. The build feels solid and thoughtfully designed for outdoor use. The companion app adds convenience by letting you choose different charging modes, including a quiet mode for overnight charging. While 24 pounds is light for this capacity, it might still be bulky for some users looking for ultra-portable options. Also, the super-fast charging requires app setup each time, which might be a minor hassle if you're in a hurry or without a smartphone. This power station suits those needing a balance of high capacity, fast and flexible charging, and durability in a portable package. It is especially useful for outdoor enthusiasts or anyone needing dependable off-grid power with multiple device support.

The OHOVIV Portable Charger Power Bank offers an impressive 50,000mAh capacity, which is quite large compared to typical portable chargers. This means it can recharge most smartphones, like the iPhone 15, around 10 times before needing to be recharged itself, making it especially useful for long trips or outdoor activities. It supports charging up to six devices simultaneously thanks to its four built-in cables (Lightning, USB-C, Micro USB, and USB-A) and three additional ports, which adds great convenience if you carry multiple gadgets.

The power bank also supports fast charging at 22.5W, which is faster than many standard chargers, helping reduce wait time when topping up your devices. Its compact size and weight (just over 1 pound and roughly 6 by 3 by 1 inch) make it portable enough to fit in a backpack or large pocket, although it is slightly heavier than smaller power banks due to its large capacity. Safety is well covered with multiple protections against overcharging, short circuits, and overheating, utilizing smart chips and temperature control technology to keep you and your devices safe.

On the downside, the fast charging speed, while good, is not the highest available on the market, and the charger does not include a wall adapter, so you'll need to use one you already have or buy separately. The built-in cables are a nice touch, but they might limit flexibility compared to using your own longer or specialized cables. This power bank is well suited for travelers and heavy device users who need a reliable, high-capacity charger with multiple outputs and safety features, though it might be bulkier and slower than some specialized fast chargers if ultra-fast charging or ultra-lightweight design is your priority.

This portable charger offers a 10,000mAh capacity, which is a solid middle ground for daily use, providing roughly two full charges for most smartphones. Its standout feature is the built-in cables—three output cables (including Lightning, USB-C, and Micro USB) and one input cable—which means you don’t need to carry extra cords, making it very convenient for travel or busy days. With six output ports in total, you can charge up to six devices at once, which is excellent if you have multiple gadgets or are sharing with others. It also supports three different input options for recharging the power bank, adding flexibility.

The slim and lightweight design, about the size of a lighter and weighing less than 9 ounces, makes it easy to carry around in a pocket or bag. The digital LED display showing the exact remaining battery percentage is a useful touch to avoid surprises about power levels. It’s compatible with a wide range of devices from iPhones to Samsung and other USB-C or Micro USB products. A 10,000mAh battery might be limiting if you want to charge larger tablets multiple times or rely on it for extended trips without recharging.

This charger suits everyday users who value convenience, multiple device charging, and portability, but those who need heavy power capacity or advanced safety certifications may want to consider other options.
