These days there quite a few people using smartphones and tablets on a regular basis but there’s always a problem when it comes to battery life and keeping tech devices charged throughout the day.
Unless you’re able to keep your device plugged in all day or you have access to a plug when the battery dies then the next best thing is to consider using a portable power bank.
These are basically huge batteries that you can charge up at home and they’re able to retain their charge until you plug something, in usually through a USB port.
With one of these it’s possible to use a tech device throughout the day and once it runs out of batteries you can plug it into your portable power bank and keep using it while it charges up.
This means that whether you’re out hiking, exploring the city, taking the bus, or just at work without access to a plug you’re still able to keep your devices charged and you can keep texting, making calls, or browsing the web until you get home and can plug it in again.
I recently actually started using one so I began a search for the best portable power bank so that I could keep my iPad charged as well as top off my Samsung smartphone whenever it started to run out of battery life.
I quickly noticed that there were two different types available – bigger, heavier ones and smaller, more lightweight ones.
The bigger ones are able to retain more of a charge and can be used to fully recharge things like smartphones and tablets or even camera batteries if they’re able to be plugged in through a USB just like the GoPro ones and with the bigger ones it’s also possible to charge smartphones a few times before they run out.
The drawback with a bigger power bank is that it’s heavier and it’s going to take longer to charge up at home and you might not need it if you only need one or two smartphone charges during the day.
The smaller and more lightweight options are easier to carry, don’t take up as much space in a bag, and typically able to provide a smartphone with one full charge but they won’t always be able to completely charge a tablet.
Along with one of these you could also consider using a USB car charger if you’re spending a lot of time in the car or if you notice that the battery life on your device is getting quite bad you can either pick up a spare battery or look at upgrading.
Having a portable power bank is something that anybody that’s doing a lot of traveling or spending a lot of time away from a plug where they’re not able to charge the device should consider picking up so that it’s possible to keep using the device without having to worry about battery life as much.
One of the main overall drawbacks is that you’re going to have to worry about keeping the power bank charged and it’s just one more thing that you have to carry with you throughout the day but it definitely helps in a pinch and will allow you to keep your devices charged up and ready to use.
In this post I want to go over some recommendations when it comes to the different portable power banks that I recommend using for smartphones or tablets.
The Best Portable Power Bank
Anker PowerCore+ mini 3350mAh Portable Charger
When it comes to the best portable power bank it was the Anker PowerCore+ mini 3350mAh Portable Charger that I found to be the most suitable choice when looking at size, portability, and ease-of-use.
Although it’s not the biggest when it comes to battery size it’s the overall size of this portable charger which is why I recommend it and why I think it’s one of the best, especially if you’re looking for something small to carry around with you on a regular basis.
It’s just 3.7 inches in height when you’re standing it up and it has a 0.9 inch diameter so as you can imagine it’s not as big as some of the more boxy and heavy duty ones that you can find online.
As you can see in the title it has a 3350 mAh battery capacity and it’s able to provide up to 1 amp of charging speed.
What this means is that it’s able to fully charge an iPhone 6s up to 130% of its battery life and if you have a bigger smartphone or tablet you’ll be able to get quite a significant percentage of a charged as well.
You could also use it with a portable tablet stand so you could get more life out of the device before you have to charge it again.
There’s only one USB port so you can only use it for charging one device at a time and it features an aluminum body that keeps it lightweight while still allowing it to be quite sturdy and durable for regular use.
Depending on your preferences there are also a few different colors to choose from and if you’re looking for something small, portable, and lightweight it’s this one that I would recommend taking a look at.
Jackery Bar Premium 6000 mAh External Battery Charger
Compared to the previous option that I just recommended the Jackery Bar Premium 6000 mAh External Battery Charger is much bigger in both size and total battery capacity.
While this does mean that it’s heavier and a little less portable you’ll be able to use it to get more battery life out of your device and it’s still a suitable choice when it comes to a portable power bank.
This one is able to charge your standard iPhone 2 or 3 times before it runs out and it’s also possible to use it for a full tablet charge depending on the size of the device that you’re using.
It’s compatible with iPhones, Samsung Galaxy phones, a variety of other popular devices and I can even be used to charge GoPro batteries as long as you have a suitable charger that’s powered by USB.
It’s still quite small, weighing in at just 5.3 ounces, and it takes approximately between six and eight hours to fully charge the charger itself.
The charger takes advantage of an aluminum shell that keeps it lightweight and portable while still being durable and well suited for regular day use and it uses Panasonic battery cells for holding a charge until you’re ready to use it.
Thanks to the 6000 mAh battery capacity it’s able to charge smaller smartphone devices 2 or 3 times before it runs out and you can even use it for fully charging a tablet at least once as long as it’s one of the smaller ones.
There are a few different colors to choose from depending on your preferences and despite this one being bigger than the previous Anker that I just recommended it’s still a good size to use for traveling or carrying around during the day for keeping devices charged and ready to use.
Anker PowerCore 10000
The Anker PowerCore 10000 is a portable charger that offers quite a decent size of battery capacity at 10,000 mAh and can be used to charge the iPhone 6s nearly three and a half times or the Galaxy S6 about 3 times on a single charge.
Not only does it have such a large battery capacity but it’s also portable and weighs just 6.4-ounces so it’s not too big and it can be easily tossed into a backpack, purse, or even your pocket.
Depending on its size it can also be used to charge a tablet once and it’s also possible to use it for GoPro batteries or just about anything else that is charged through a USB cord.
Speaking of USB, this charger offers just a single USB port for charging and it’s compatible with both Apple and Android smartphones and tablets.
With such a large capacity I would definitely recommend the Anker PowerCore 10000 for anyone that finds that there phone is running out quite a bit throughout the day or wants to use it to keep one or two different devices charged and ready to use when there isn’t easy access to a power outlet.
Anker PowerCore 20100
The Anker PowerCore 20100 is an even bigger portable power bank than the previous ones that I’ve recommended and it’s great if you’re using a combination of smartphones and tablets or you need to charge more than one smartphone at a time.
Thanks to the 20,000 mAh Battery capacity it’s able to charge an iPhone 6 more than 7 times and it can be used to charge an iPad Mini more than 2 times from a single charge.
This gives you somewhat of an idea of what you can expect if you’re using a similar phone or tablet and it actually comes equipped with 2 USB charging ports so you can use it to charge 2 phones or 2 tablets or one of each at the same time.
I really like being able to take advantage of the 2 USB charging ports since sometimes when I’m out traveling I need to charge more than one device at a time and the large battery capacity really helps when it comes to keeping devices charged without having to worry about finding an outlet or if the portable charger is going to run out too quickly.
It is definitely a bit heavier than some of the other ones have recommended here and it weighs in at about 12.56 ounces so I find it to be still quite reasonable in size and weight and still portable enough that I can toss it into my backpack and carry it with me throughout the day.
Depending on your preferences there are two colors to choose from, a black one and a white one, and it even comes with a traveling pouch to help keep it protected when it’s in your backpack or luggage or even in your pocket.
One more interesting feature is that it offers an output of 4.8 amps and this means it’s possible to charge a combination of two different devices at the same time at full speed without having to worry about one or the other taking up too much power or not getting enough charge.
I would definitely recommend checking out the Anker PowerCore 20100 if you’re doing a lot of traveling or if you constantly find that your devices are running out of battery charge too soon throughout the day and you want a portable charger that you can use to charge up to two different devices at the same time.
EasyAcc Monster 20000mAh Power Bank
The EasyAcc Monster 20000mAh Power Bank is one that I would recommend checking out if you’re looking for a power bank that comes equipped with 4 USB ports so that it’s possible to charge up to four different devices at the same time.
This one is pretty well suited for those traveling with more than just one or two different electronic devices that can be charged up by USB and if you’re like me and you are bringing around a smartphone, tablet, and something like GoPro batteries then it’s one that I would recommend taking a look at.
It offers a pretty nifty battery capacity of 20,000 mAh and just for reference it’s able to charge an iPhone 7 up to 6 times and it can even be used to charge the iPad Mini 3 up to 2 times.
You could also use it for keeping other devices charged, such as an MP3 player or even camera batteries.
This should give you an idea of what you can expect with such a large battery capacity and I find it to be a suitable choice for those that are carrying smartphones or tablets with them on a regular basis whether at work or traveling.
The four USB ports really opens up the capability that this portable power bank offers and it’s even good if you’re traveling with a friend or if you want to share power with someone else that needs to recharge something.
Another neat feature is that it also comes equipped with an LED flashlight that’s built into the charger itself and can be used in any low-light situations or even if the power runs out.
There are a few different color combinations to choose from depending on what you’re looking for and this guy weighs in at about 454 grams so it’s not the lightest option on this list but it’s still light enough that you can pack it away in your backpack or even in your pocket if you need to bring it with you during the day.
FKANT 15000mAh Portable Solar Power Bank
The FKANT 15000mAh Portable Solar Power Bank is actually pretty interesting because as the name suggests this is a solar powered power bank so you’re able to charge it up as long as the solar panel is able to absorb sun.
Not only can you use it outdoors in direct sunlight to charge it up but it can also be plugged in to charge so it’s great to use at home and just to have around if you’re spending time hiking or camping and you want to keep your devices charged or if you’re worried about power access during a power outage.
One problem that I usually run into with my smartphone is that when I’m going camping or spending time hiking I always run out of batteries after one or two days and then I’m in the dark until I’m able to plug it in when I get back home.
With the FKANT 15000mAh Portable Solar Power Bank it’s possible to charge my phone in the backcountry and stay connected while still being able to use it for taking photos and referring to the maps as well.
It comes with 2 USB ports so it’s able to charge up to two different devices at the same time and it’s compatible with the iPhone 6 series phones along with the Samsung S7, S6, and many other standard popular phone brands.
It’s very small and portable and it even comes with a carabiner clip so that it can be attached to the outside of a backpack so that it can continue to charge up even when you’re hiking around.
I would definitely recommend checking this one out if you’re spending a lot of time hiking, camping, or you’re outdoors a lot without direct access to an outlet where you can just plug in your smartphone or tablet and keep it charged.
Keep in mind that this is going to need fairly direct sunlight for it to charge up but otherwise it’s a suitable choice for keeping your devices charged either during a power outage or when you’re spending more than just a day or two away from home.
RAVPower Portable Charger 22000mAh
The RAVPower Portable Charger 22000mAh boasts a pretty hefty battery capacity and comes equipped with three different USB ports that offer a maximum of 2.4 amps per port of charging capability.
With this nifty little power bank you’re able to charge two different iPads and even an iPhone 6s at the same time where you’re still able to take advantage of their ideal charging speed and this is pretty awesome if you’re traveling around with a lot of different devices or if you and your friends want to keep your devices charged throughout the day.
Depending on which device you’re using it’s possible to charge and iPhone smartphone anywhere between 5 and 9 times depending on the model and it’s possible to enjoy more than 3 full charges of an iPad Mini with the power bank fully charged.
This should be able to give you a better idea of the charging capabilities that you can expect and just keep in mind that it’s dependent on the device you’re using but relatively having more than 20000 mAh of battery capacity is going to give you a decent amount of charges.
The exterior carrying case is made from a thermoplastic alloy material and at just 14.4 ounces it’s quite lightweight and not much of a hassle to toss into a backpack and carry around during the day.
