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 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.

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.

More than just a laptop charger, this 32000-mAh capacity portable charger will provide more than one full charge to most laptops and can give 15 or more charges to your smartphone. It can charge three devices at one time and features a smart LCD screen that displays the power level, charging and discharging status. This charger also comes with a UK, US and EU power adapter, making it perfect for travel. It’s a bit heavy at 3.2 pounds, but it's still a great value. It comes with a 12-month replacement warranty, a 30-day money back guarantee and a lifetime support guarantee.

This external charger has the capability of charging your laptop, as well as two USB devices at the same time. It comes with a number of connectors and has adjustable voltage outputs to meet the needs of your various devices. An LCD display window lets you know exactly how much power you have left, and as a safety feature this charger will automatically shut off when a short circuit or overload happens, in order to keep your devices safe. The ten included notebook connectors will fit DC models A through K and each USB output is 5V. This is a little heavier and larger than the RAVPower model, at 8.5 x 6.9 X 3.3 inches and 2.1 pounds, but it’s still worth buying, especially with the 24-month limited product warranty. With the low price and the ability to adjust the voltage needs, this charger is a great for someone who has a variety of devices with differing power requirements; it also eliminates the need to buy multiple portable chargers.

The XTPower MP-30000 charger is brick shaped as opposed to the other models, which are long and flat. It’s a very reasonable price, and contains the standard three outputs (one laptop, two USB). Easy to use, this model can be operated with only one button. The XTPower charger also comes with a 10-laptop DC adapter, a 70cm DC cable and a 70cm USB to Micro USB cable. And it will fit DC output models A through M with its DC adaptor cable. Despite its brick-like shape (,8.46 x 3.15 x 1.51 inches), this model only weighs 1.81 pounds.

Available in both black and silver, the aluminum body Lizone is just 1.5 pounds and measures 6.5 x 4.8 x .8 inches. It can perform more than 600 charges over its lifetime and it has a battery bar on the side that displays the current charge of the external battery. Alongside your laptop, the Lizone can power your iPhone 6s Plus more than 14 times before running out of power. However the DC output port likely means you’ll need to provide your own cable.

This charger is available in black, silver and pink, and is compatible with a variety of popular laptops and notebook-style devices. It is powered by a rechargeable Lithium-Ion 33600 mAh battery. The specifications are 15V input and a 24V output 15V/20V – 125Wh.
