Gone are the days when going camping or suffering a power outage meant you had to live without electricity until your trip was over or the power was restored. These days, portable power supplies make a much more luxurious “glamping” experience possible.

Modern portable power supplies have built-in inverters that make them capable of charging AC devices, and they can be recharged using solar or your car’s battery – making it possible to live entirely off the grid. Whether it’s your smartphone, microwave, television, or heater, you no longer have to sacrifice your creature comforts in return for an adventure in the great outdoors.

Sold on the benefits of a portable power supply and looking for some direction on which one to buy? Read our buying guide to the best portable power supplies based on factors such as capacity, amount of outlets, recharge time, and value for the money. You’ll be fully charged and ready to go in no time!

Best Portable Power Supply Buying Guide & FAQ

Feeling overwhelmed by the amount of awesome portable power supplies available? Allow our buying guide and FAQ to help you decide which one is best for you.

Benefits of Portable Power Supplies

Live Off-Grid

A portable power supply allows you to make (if using a solar panel), store, and use your own power, independent of the power grid. This means you can have power in remote places and is particularly beneficial for van-lifers, campers, and travelers who like to get off the beaten track, but don’t want to sacrifice their home comforts.

Health Benefits

The benefits of using a portable power supply are not only related to comfort, but a necessity – from sleep apnea sufferers using CPAP machines, to diabetics using mini-fridges to store insulin, there are numerous ways in which portable power supplies support our health needs, and open up the camping experience to more people.

Work Remotely

A portable power supply offers remote workers the ability to recharge and power their laptops, phones, and other devices from anywhere, without having to rely on coffee shops or co-working spaces — work in the park, or at the beach!

Emergency Power

Finally, portable power supplies are not exclusive to those who want to transport their power — sometimes, the power is also needed at home. In areas prone to storms and/or power outages, a portable power supply can be a lifesaver, allowing you to power communications devices, lighting, and essentials, until mains power is restored.

Features to Consider When Buying a Portable Power Supply

Devices and Wattage

This is one of the most important things to consider when buying a portable power supply, as it affects the power capacity and number of outlets your battery will need. Consider how many devices you want to be able to charge and whether you want to charge them simultaneously. If so, work out how much power they each draw, and choose a power supply with enough outlets, that’s capable of supporting their combined wattage (try to find one with more power than you need, as many batteries struggle when close to their maximum).

How it’s Recharged

Consider also how the battery is recharged. Is it only via an AC-outlet, or can you use a car-port or solar panel? For example, if you’re going wild camping for an extended period of time, you’ll likely want a battery that can be recharged using solar, which will allow you to go completely off-grid. Make sure your solar panel is the correct wattage and voltage for the battery.

Automatic Shut-Off

This is an important factor to consider if you’re using devices that draw a low wattage (less than 10W) – for example, some CPAP machines. Many portable power supplies shut-off when the wattage gets too low, which is obviously a problem if you’re relying on it to run your machine whilst you sleep.

Portability

If you’re going to be using your portable power supply for camping or traveling, you’re going to want something that’s lightweight and not too bulky or difficult to move around. In this case, a lithium-ion battery will definitely be the better choice, as they are significantly lighter than lead-acid batteries, as well as more long-lasting.

A portable power supply is convenient and easy to store.

Types of Portable Power Supplies

Gas generators offer a higher power output than AC power supplies of a similar budget – you’ll be able to run power-hungry appliances such as hairdryers and electric kettles, which are impossible with most AC power units. However, there are a few key differences that will influence which type of power supply you choose.

AC Powered

AC-powered portable sources require little maintenance and run quietly, making them a welcome choice at campgrounds and similar locations where supplies and noise are minimal. These units include a pure sine wave inverter to translate battery-derived DC power into readily-usable AC power. Thanks to their minimal weight and size, most portable solutions will rely on a lithium-based battery to store and share power, although a few units may feature heavier, more traditional lead-acid batteries instead.

Solar-Powered

Solar-powered portable power supplies tend to be relatively small and are mainly intended for charging cell phones and other small devices. Often, the power generators are lightweight and packable (often foldable) so they can fit better into backpacks and other spaces where space is limited. This combination of features limits them to emergency backcountry uses rather than providing campsite power to CPAPs or other items with larger power draws.

Gas Generator

Gas generators require the regular purchasing of gasoline to power them. Another downside of gas generators is that they emit fumes and are very noisy to run, whereas portable batteries are cleaner and usually silent. For this reason, the use of gas generators is banned or restricted at some campsites. Certainly, if you wish to make friends with your neighbors, a portable AC power supply is the way to go.

Best Portable Power Supply FAQ:

Q: What is a portable power supply and how does it work?

A: A portable power supply is exactly what it sounds like: a portable battery that you can take with you wherever you go, with outlets that you can use to charge and power your devices, without depending on a mains power supply. Unlike gas generators, the power comes from a rechargeable battery, which, depending on the model, can be recharged using an AC-outlet, car-port or solar panel. The battery then stores this power, ready to transfer into your devices when required.

Q: Can I use a portable power supply on a plane?

A: Policies on portable power suppliers vary between airlines, so make sure to check your chosen carrier’s guidelines. As a general rule, you are allowed to take lithium batteries up to 100Wh on most planes. Batteries up to 160Wh will need special airline clearance, and above that is a no-go. The ChargeTech Portable AC Power Supply at number 9 is the only battery on this list suitable for airplane travel. Lithium batteries must be carried in your hand luggage, not stored in the hold.

Q: How long will batteries last?

A: Battery life will vary depending on the model you purchase, and how you use/recharge your portable power supply, but all batteries will deplete over time (usually after 2 – 3 years). In order to prolong battery life, you should always follow the manufacturer’s instructions regarding discharging and charging the battery on its first use and continue to recharge the battery regularly (at least every 3 months).

Q: Can a portable power bank power a TV?

A: Yes, but with limitations. Portable power stations use a pure sine wave inverter with an output capacity between 100 and 500 watts. The average 30-inch LED TV uses roughly 50 watts of power while a 30-inch plasma TV consumes 150 watts. (50-inch TVs use roughly twice these amounts.) Many portable power sources max out at 200 to 300 watts/hour which means the average 30-inch LCD TV could run for roughly four hours while a 50-inch plasma TV would last less than one hour. As such, TVs are best paired with a dedicated power bank rather than a shared one.

Q: How do you charge a portable power pack?

A: Charging a portable power station will vary from unit to unit. Most units rely on a traditional AC power outlet to recharge, although they frequently will support charging via other sources as well. Common alternative charging sources include 12-volt DC car charging ports and solar panels. Often, the 12-volt car charger will be included with the power pack, but usually, a compatible solar panel will only be available as a separate purchase, often from a third-party manufacturer.

Our Top Pick

While our list of the best portable power supplies is extensive, our top pick has got to be the Jackery Portable Power Station Explorer 300. This compact unit is the ideal combination of performance, reliability, and price. This unit features plenty of charging outlets that allows you to charge up to six devices simultaneously.
