The 8 Best Portable Laptop Battery Chargers of 2019

The MAXOAK External Battery is a versatile power beast. First, it features six charging ports. One is a 20-volt/3-amp port for laptops, one is 12-volt/2.5-amp port for digital cameras, two are 5-volt/2.1-amp USB ports and two 5 volt/1 amp USB ports. Second, it has 50,000 mAh of battery life, meaning you could recharge your laptop and phones many times before having to recharge the external battery power bank. Third, it measures just 8.1 x 5.3 x 1.3 inches and weighs 2.77 pounds, so it could easily fit into your camping bag and it won’t be that much heavier. Finally, it includes 14 types of laptop connectors, so it covers most models but not Apple laptops. If you don’t have an Apple laptop or a laptop that uses USB Type C, you’ll likely be able to plug it in, but be sure to check if your laptop is supported before purchasing.

The Jackery portable charger has a slightly different look than most of the slim, rectangular chargers you’ll find on this list. But the brick-looking, tower aesthetic is pretty refreshing on this device. They’ve done this to minimize weight, and it weighs only 1.5 lbs, which the company promises will be ideal for camping and on-the-go outdoor activities. The 85W A/C output is designed for all the latest laptops, including 12-inch MacBooks, the new MacBook Pros, Dell & HP laptops, the Microsoft Surface and more.

On the flipside, there are a few varieties of USB outputs from USB-C to the new USB 3 for the fastest charging at 5V/2.4 amps. The device promises 6 to 10 full charges for iPhones, 6 to 10 full charges for Samsung phones, 8 to 10 cycles for GoPros and 1 to 3 charges for tablets. There’s built-in protection for temperature overheating, unexpected surges and overcharges, so you won’t mess up any of the devices you’re trying to juice up. The company has even taken steps to make sure the device meets TSA regulations in case you want to bring it in your carry-on.

ChargeTech Enterprises is a fascinating small company that got its start on Indiegogo, raising about $450,000 to make “the best portable AC power supply.” Since that time, the ChargeTech Portable AC Battery Pack has become a popular item that anyone can buy on Amazon. This unit measures 7.5 x 5.2 x 1 inches and weighs 1.56 pounds. It offers 27,000 mAh of battery and can charge electronic items that are up to 85 watts, including laptops, digital cameras, curling irons and more. On top of having an AC outlet, it also has two USB ports that charge at 2.4 amps, so you can easily charge your phone or tablet too. On the top of the unit, you’ll find four blue LED lights that tell you how much battery the device has left. Keep in mind that with this battery only being able to charge electronics up to 85 watts, you’ll want to closely check the settings on what you are attempting to charge before charging.

Between the Bluetooth speakers and portable charging options, Anker has a lot to offer the space of mobile tech. The PowerCore+ is a sizeable charger for any tech, but the fact that it offers USB type C Power Delivery means it’s perfect for charging MacBooks and other USB-C devices. It contains both USB-C ports and USB-A ports, the former offering 30W output and the latter putting out 5V and 3A of power. This compatibility will let you charge anything from iPhones to Android devices, all the way to tablets and the aforementioned laptops. The battery sports 26,800 mAh of charge, which the manufacturer promises is enough power to recharge an iPhone X as many as six times. It will charge a full laptop far less, but that’s to be expected. The bundle also comes with a 30W USB-C wall charger with Power Delivery — a nice bonus that will also work for laptops and other high power devices like pro-level tablets and the Nintendo Switch.

The Crave PowerPack CRVPP101 is a powerful portable charger for recharging nearly any device you can throw at it. It measures 6 x 8 x 2 inches, weighs two pounds and has 50,000 mAh in battery capacity, which means it could charge your phones and laptops multiple times before it needs a recharge. For ports, the device has four USB charging ports and two laptop power supply ports. It’s compatible with many laptop brands, including Sony, Acer, Dell, IBM, Fujitsu, HP, NEC, Toshiba, Samsung and Lenovo. However, it does not work with Apple laptops and you should be sure to check if your specific connector is compatible with this charger before purchasing. Also be sure double check that your laptop charger draws less than five amps for compatibility. On top of all these features, it also includes a micro-USB cable and a travel pouch, so you can go anywhere with it, whether it’s camping or a road trip.

Many of RAVPower’s options center on mobile devices and tablets, so you’ll have to choose a USB-C power delivery option like this one if you’re looking to charge up a laptop. That Power Delivery tech amounts to 30W of continuous power, so look for that when going for a portable laptop charger (note that it might be referred to as “PD” on the product description). It’s a 26,800 mAh battery pack that will recharge itself in four to five hours and hold enough juice to charge up a MacBook and an iPhone 10 times, an Android around six times, and more (though it’s important to note that these estimates are only just that: estimates). The LED indicator on the outside is clearly visible and readable to determine the battery level. It also offers a 2.4A USB charger for mobile devices, and it’s housed in a wear-resistant shell that looks and feels good.

Next up, we have another high-capacity 50,000 mAH external battery. Measuring 8.15 x 1.3 x 5.35 inches and weighing just under three pounds, the PowerOak packs a powerful punch into a small package. It makes for a great road trip companion, but due to the high voltage, the device is not approved for air travel. The PowerOak offers six output ports, each with a different voltage, to accommodate the charging needs of a wide range of devices. It contains one 20V/5A port for laptops, one 12V/2.5A port for digital cameras, two 5V/2.1A and two 5V/1A USB ports for tablets and smart phones. The PowerOak comes with 14 laptop adapters which are compatible with almost every major electronic brand including Samsung, Dell, Lenovo, HP, ASUS, and other Windows PCs. 

The PowerOak’s high charging capacity promises quick charging speeds and protection against short-circuiting or overheating. Its lithium-ion polymer battery is equipped with six layers of security, ensuring safe use for at least 1,000 recharge cycles. The device also features a fire-retardant, corrosion-resistant, aluminum exterior, which keeps the charger looking brand new even after months of use.
