10 Best Portable Chargers Fully Reviewed

last updated Nov 23, 2018
There’s nothing quite as frustrating as being stuck far from a wall outlet and seeing your phone screen dim because of a low battery. Runners understand this all too well, especially distance runners who prefer more secluded routes. Not only is this inconvenient, but it’s also dangerous under certain circumstances. If you enjoy running by yourself, having a cell phone or GPS locator is always a good idea. All it takes is one twisted ankle, or a hard fall, to create an emergency situation. Dedicated runners also understand the importance of music or tracking their performance.

No one likes it when they’re really into a run, listening to their favorite songs, and suddenly the music player dies. This can throw off your entire rhythm and can make those last few miles seem like they’re taking forever. These are all things that can be easily solved with a lightweight portable charger. This is a device that you can carry with you while you run to ensure that you’ll never deal with a low battery again. Consider it an extra safety measure.

We’ve looked at some of the best portable chargers on the market to find the ones that would offer the most for runners, and other people who enjoy the freedom of not being tied to a wall outlet.

The right portable charger will provide you with peace of mind and the option to be able to charge your devices while on the go. We’ve taken a look through a ton of options, coming up with ten that we like the best.

Durability

The anti-fingerprint exterior ensures that your portable charger doesn't instantly look dirty when you handle it. It's also backed by a one-year warranty. There aren't a lot of buttons on the device either, just an on/off switch, so that helps with overall durability. Safety features ensure the device doesn't die before you get plenty of use from it and that it doesn't damage any item you're charging.

Criteria Used for Evaluation

Portability

No one wants to lug around a portable charger that weighs more than all of their gear put together. It should be easy to carry and light enough to travel over long distances. It should also be small enough to fit in a compact space. Runners don’t like to carry a lot of additional things that can weigh them down or make the process awkward. All of the models that we’ve chosen can easily fit in a bag, or in a larger pocket. They’re also durable enough to withstand the bouncing around that happens on longer runs. Our top pick is one of the most compact options available, and that packs a lot of power for its size.

Use

When we reviewed these products, we kept the purpose of the portable charger in mind. This is, of course, to charge whatever devices your caring with you. There are a number of different charge capacities, and each one is appropriate for different situation. Chargers that have a 5000mAh capacity provide the least amount of battery power and can usually be used for single charge. These are great for short runs or just to take along every time you go out in case of an emergency. They were great in a pinch but may not do as well over longer distances or trips that last several days.

For Smartphones or smaller tablets, you may want a charger with a capacity of around 10,000mah. These may not be electronics you carry with you while you run, but they definitely come in handy on camping trips or outings. If you’re the type of person that can’t go anywhere without a laptop, you’ll definitely want to consider a portable charger with a capacity of 20,000mAh or more. These will be able to charge your Smartphone several times or get your laptop up and running after you drain the battery. Most of the devices that we reviewed are capable of at least charging a Smartphone more than once.

Durability

Any time that you’re depending on a device like this for a potential emergency situation, you want to make sure that it can withstand a little bit of abuse. The more durable your portable charger is, the more likely it is to come through when you really need it to. A lot of models come with their own carrying pouches that can absorb some of the shock and help protect them. This can only get you so far, and the actual quality of the device matters as well. The exterior should be heavy, thick, and provide adequate protection for the sensitive interior. These may not survive being stomped on or dropped down the side of a cliff, but they’ll definitely last through normal wear and tear.

Advanced Features

We live in a high-tech world, and almost everyone has some sort of electronic device they carry with them. Whether it’s a phone, tablet, or a laptop, technology keeps us connected. Runners have a particularly close relationship with their smart phones and music players. For longer trips that involve camping or an overnight stay somewhere primitive, you’ll definitely need to consider a portable charger with multiple USB ports. This allows you to charge more than one device at a time, and gets you connected to civilization that much faster. These aren’t always appropriate for short runs or instances where you’ll only need a single phone charge, but they can be an absolute lifesaver when you’re stuck in a tent with no wall outlet in site.

Most portable chargers have similar charging speeds. Charging is much slower than charging your device using a wall outlet charger, but it’ll do the job. Some devices are capable of charging up slightly faster than others but don’t expect miracles. A portable charger must also be charged and usually, this process is fairly slow across the board. Don’t fall for claims about super fast charging.

Many portable chargers are capable of adjusting their charging speed according to the device plugged in. Units with dual charging ports will charge your devices simultaneous but at separate speeds depending on what is more efficient. Most chargers also have intelligent safety features built-in to the design to eliminate any potential damage that may occur to your device during charging. No need to worry about overcharging or power surges. Pay attention, too, to whether a portable charger support through-charging. This means that the unit can charge devices while it is itself plugged in and being charged. It’s a useful feature but not supported by all portable chargers.

Other Factors to Consider

Bottom Line

How did we pick out our top ten list? While we definitely chose models that received rave reviews from users, we also considered portability, durability, charge capacity, and multiple device support.

When thinking of purchasing a portable charger, there are some other things to think about. You want the charger to be easy to use and intuitive to understand. You should look at how quick it is to charge and at what speed it can charge your devices. Price is important, too, as are any smart technologies included in the charger.

Ease of Use

How easy is the device to use? Do you need a degree in engineering to figure it out? Most devices of this nature are super simple to use but make sure you can understand the indicator lights (if there are any) and you’re comfortable with how the unit functions. Pay attention, too, to whether the device supports your particular Smartphone model. For instance, Apple device users may need some kind of special adaptor to support charging. Most portable chargers are quite simple to use and come packaged with a USB cable to use with your device. The indicator lights let you know how much charging power is left on the unit. Typically, portable chargers have four lights to indicate that there is 100%, 75%, 50%, or 25% charge left, but that may vary depending on the charger in question.

Value

An obvious consideration is the price of the unit you’re considering. In general, portable chargers with a higher price tag will be of higher-quality and offer a higher charging capacity. But, that’s not always the case, which is why it’s important to take a look at user reviews. There are great portable charger options available for budget pricing.

Frequently Asked Questions

q: Q. Is a portable charger just good for charging a phone?
a:

A. No. You can charge many things using a portable charger. A larger capacity will ensure you have enough juice to power up a laptop, if you need to, for instance.

q: Q. How am I supposed to know how much battery power is left on my portable charger?
a:

A. Most units have LED lights to indicate the amount of charging power left. Check your device’s manual to find out what each status light means.

q: Q. How do I actually charge the portable charger?
a:

A. Initially, charging the device itself may take some time. It depends on the model and capacity in question. Most devices come with a USB cable that you can plug into a wall adapter. Some devices may come with the adapter needed for charging, others may not.

q: Q. I should go with the highest capacity portable charger, right?
a:

A. Wrong. Higher capacity doesn’t necessarily mean the device is a better choice for you. Portable chargers with higher capacity are usually heavier so you need to weigh the pros and cons of carrying around a device with more battery power. If you’re looking for something super lightweight, a smaller portable charger with less capacity might be a better option.

q: Q. What kind of output should I be looking for?
a:

A. You’ll notice that manufacturers of portable chargers list the amperage output of their ports. This basically helps you to figure out the speed at which your device will be charged. If you want to charge a larger device, go with a 2A output.

q: Q. How long will a portable charger last?
a:

A. It depends on the model in question. Most should last around 500 charges but that’s not a hard number. After a while, you’ll notice it takes longer to charge up the device itself and that it doesn’t hold its charge as well as before.
