Features To Consider

Portable battery varies a lot in size, shape and extra features. However, we have compounded these essential features to help you pick the correct one for your desire and budget


Obviously, one of the largest determining factors when choosing the right portable battery for you is just that: portability. Is it easy to carry along with you and not proving to be an inconvenience? The size and dimensions are important in anything you choose to take with you when you travel.

Portable Battery in pocket

Whether the size is determined by a hiking pack where every ounce counts or you have special supplies for hunting or fishing equipment that automatically make the cut, the portable battery should be the appropriate size to help you to never carry more than you need while not sacrificing safety.

Every outdoorsman has their set supplies needed for the type of excursion they are embarking on and the battery should be added to the list. It’s not something that takes the place of other supplies. It should be small enough to go unnoticed, but large enough to do its job well.


Weight and dimensions go hand in hand in the sense that they are the main part of the decision behind a purchase. It’s always a balance of heavy versus capabilities. The bigger, isn’t always the better, but neither is the smallest.

In the end, the buyer has to ask themselves if this portable battery has all of the functions they need while maintaining the ability to fit within their needs before hitting the trail or packing the suitcase. The ideal portable battery would fit into a many different parts of life, not just outdoors.

A portable battery should bring safety and peace of mind to the hiker and backpacker, it should bring added benefits to the fishermen and hunter, it should also give the student or employee piece of mind when traveling abroad or cross-country. The most fitting portable battery for you should be the most versatile as well.

The mAh

The mAh stands for the milliamperes per hour (milliAmp hour) and it refers to the measure of a battery’s storage capacity for the energy that it holds. For example, picture the portable battery like the fuel tank in your car.

The mAh is just a measure of how much hypothetical “fuel” your battery can hold- the more fuel, or energy, the better. This is also an indicator of size and weight. The larger the mAh the battery holds, the larger the battery will physically be. This also correlates well with the devices you might be connecting to your portable battery.


If you want a small, lightweight, portable battery, then you may not be able to charge your laptop all the time with a lower mAh battery. The technology behind these batteries really is amazing. For example, the standard iPhones have a capacity of between 1420-1800, therefore, to fully charge an iPhone one time, you would need at least 2000 mAh in capacity.

Charge Output & Protection

Charge output indicates how powerful the output is to charge various devices. This could be a deal-breaker for some consumers. We want the best of both worlds, something that charges quickly, but gives enough power to other devices for charges that will last much longer.

To put this into perspective, most smaller devices such as cell phones or digital cameras only require 1A (amp) of output to charge them.

In contrast, larger devices that use more power to run such as laptops or tablets, often require more than 2.1A (amps) of output to charge them effectively. This means that the smaller portable batteries may hold a lot of mAh storage, but if their output isn’t strong enough, they will not be able to charge larger devices as well as you might like.

Another aspect of charge output is based on how well the battery will protect itself. Often times, devices get burnt out or worn down because they are charged for much longer than necessary at full power.

If you leave your smartphone plugged into the wall even when it’s at 100% charge, the battery will begin to deteriorate because the current is constantly flowing into it even when it doesn’t need it. Some of the highest quality batteries actually monitor themselves.

Making sure never to send too much current into another device or avoiding short circuits in the event of power surges or losses and much more. These are just a few ways to preserve the life of your battery and the life of the devices it may be charging.

Features & Uses

Each portable battery comes with a variety of uses. Most come with a standard cord, but many have various plug-in types and places. These can be used to charge any number or types of devices you might need as long as the cords are compatible. There are also specific devices that some portable batteries can charge.

Some charge only phones or tablets, others charge phones, tablets, laptops and more. Some even charge your car battery if it dies! There are so many uses for each of these portable batteries that each one individually needs to be researched in detail before making the decision on which fits you best.

  • Both my wife and our teenage daughter love the Anker PowerCore+ mini, 3350mAh Lipstick-Sized Portable Charger. It fits in whatever size of bag they choose to carry and can charge an iPhone twice with more juice left. It looks just like a lipstick tube and its aluminum body is a thing of beauty.

  • It’s really different for women and men, isn’t it? I don’t mind carrying any black portable battery but my girlfriend on the other hand, prefers something “extra”. Although today, I noticed that both men and women not only looked at functionality but also on the aesthetic appearance of their gear. I can’t blame them, though. 🙂

  • The Crave Travel Pro 13000mAh Dual USB Ultra-High Density Power Bank was a really good find, especially for that price. At first, I was skeptical because I was not familiar with the brand but it really surprised me with its excellent performance. It is a bit on the bigger and heavier side of things but it is worth it.

  • Don’t worry the Crave Travel Pro is a good product and you get 18 months warranty on your unit. It’s a great companion for backpackers and travelers without the hefty price. It’s not bulky, either and won’t take too much room inside your bag.
