Portable power sources are a godsend in the outdoors when you have no power. What if you need to turn on your laptop to fire away a few paragraphs in front of the most stunning waterfalls? Your phone died.

You need a light. Listen to a ball game. Portable power supplies give you the freedom to operate from anywhere, anytime.

Now you can take your laptop with you to the beach and work while the sun sets on the horizon. You don’t need to worry about your smartphone running out of charge while camping. The convenience that portable power supplies provide is unmatched.

What is a Portable Power Supply?

If you are looking for a fall back power source in case of disaster-related power outages then portable power supplies are the answer. They provide an easy charging experience and can be charged from common charging sources like AC outlets or solar panels.

Devices can be plugged into three ports on the power supply source that consist of AC (alternating current), DC (direct current), and USB ports.

A portable power supply comes in handy in camping outdoors or even when you decide to have an odd night out in the car. The convenience of plugging in from anywhere, anytime is truly liberating.

Now, you don’t have to stay indoors or make sure that you are near power outlets to work on a project, watch a movie, or even charge your phone.

All your modern hi-tech gadgets and devices can be charged, panic-free, with the help of a portable power supply out in the raw nature.

Which Power Supply Should You Choose

Several factors could affect your choice when it comes to selecting a power source that meets your needs.

1. Capacity

Capacity is one of the foremost features that you should consider when looking for a power supply source. The capacity of a power source is measured in watt-hour and is represented by the symbol “Wh”.

Choose a higher Wh number if you have many needs and appliances that need charging, or if you are looking to spend a considerable number of hours outdoors with a reliable power supply.

As a common benchmark, 200Wh would be sufficient capacity for a day trip, but a capacity of 350Wh or more would be enough for powering an extensive stay outdoors with fans, heaters, and electric blankets et cetera.

With a 400Wh, you can also power appliances that require considerable amounts of power like microwaves and mini-refrigerators. It is wise to buy a higher Wh power supply so that it can be used for all purposes.

2. Output Terminals and Ports

The types and number of ports vary according to the make and model of the portable power supply. You must pick one that can not only support the number of users who will be using the power supply, but it is equally important that your power supply can support the various types of cables and gadgets to be charged.

For example, if you want to charge your smartphone or tablet, your portable power supply must support a USB cable. And, if you are looking to charge electrical appliances on a camping trip, like say electrical oven et cetera, it is also important that the power supply has a port for AC appliances.

Moreover, your car has different electrical needs and your power supply cannot be used in the same way in a car as it is outdoors.

There are different port requirements for a car and your power supply should be integrated with those needs for the best possible night-out-in-the-car experience. Your car’s batteries can become the unlikely power source if your power supply’s batteries run out.

3. Size and Weight

Size and weight are other essential features that you need to consider when choosing a portable power supply. Usually, capacity determines size and weight. So if you have more capacity then you will have a larger sized power supply.

But larger portable power supplies pose issues when you have to move them around, load them onto your car, or moving them from one place to another.

When considering buying larger capacity sources, maybe, you are better off weighing your options especially when you don’t want to lose the element of portability.

Power supplies weighing 8kg or more are inconvenient and those that are 5kg are extremely portable. Look for a sweet spot between high capacity and lightweight models.

4. Solar Charging Facility

A solar-charged power supply is always the best buy because it will give that extra freedom to charge in the daylight without requiring you to head to the nearest outlets. Just let it bask in the sun and charge its solar batteries.

The solar facility is also a lifesaver in emergencies where you are miles away from a power source or when the power has been disrupted due to unforeseen weather conditions.

5. Waterproofing

What use is spending money on power supplies that are susceptible to natural elements, like water? Water is everywhere and you shouldn’t need to be constantly worrying about keeping your power supply away from water.

Before buying, look for the IP mark to confirm that the portable power supply you are considering has been tested on waterproofing standards.

While camping outdoors, you are bound to run into a little mud and water, and it is paramount that you opt for waterproof power supplies.
