My job requires me to travel a lot, take hundreds of photos and videos daily, and edit them on the go. I am also a frequent blogger so I am also writing a lot, even during my travels.
So, naturally, I need to carry a power bank to keep my phone, laptop and iPad (that I carry occasionally) charged at all times. And after some trial and error, and some calculations, I figured I should carry a power bank with at least 20000 mAh back up.
After going through a lot (and I mean a lot) of power banks of different capacities and brands, I have established a list of the best 20000mAh power banks.
The Ultimate List of Top 9 Best 20,000mAh Power Banks to Keep Your Gadgets Going
If you have been researching for a detailed review on power banks to make a purchase that is worth your money, read on. I have personally used each of these power banks and will not only share what’s mentioned on the packaging but also my personal experience with them, along with what I liked about them and what I hated.
So, without any specific order, let’s just get into this:
#1. Anker PowerCore – The Powerful 20100 mAh Power Bank
Weighing a little over 12oz, the PowerCore is portable, lightweight and powerful. With a capacity of over 20000, or 20100 to be exact, this power bank can easily last you through a day with enough charge to spare. Although this calculation can vary for you depending on the devices you carry and the size of their batteries. For instance, I found that a fully charged PowerCore was enough to juice my Macbook Pro only once.
This power bank does not support Qualcomm fast charging, but it does charge devices relatively quicker than a regular wall charger, thanks to its VoltageBoost technology. Using a regular 2 amp power brick the PowerCore can be charged from 0 to 100 in about 10 hours. It is a long time but since I charged it while sleeping, the time never bothered me much.
In length, it’s about as long as an iPhone 8 plus, which means you can also fit it in your pocket easily. It has 2 USB ports for output. This means you can charge two devices at the same time if need be. It’s available in four colors, including my favorite, blue, and comes with a travel pouch, in case you are that person that requires it.
#2. The EasyAcc Portable Charger
A second generation power bank from EasyAcc, this one has a capacity of 20000 mAh. It costs about $35 bucks and seems to build sturdily. The in-built flashlight is perfect for camping trips or car breakdowns in the middle of nowhere.
It has four output ports. Yes! You read that right. But that’s not what’s unusual about this power bank. What’s abnormal is that it has two input or charging ports. While it does take up more space on your wall socket, the two input ports help you charge the device in just under 6 hours. This does not mean that a single port cannot be used to charge it. However, it would take longer that way.
It comes in three color variants with black being primarily present in all of them. The color options are only for the accents. And some color options may set you back a dollar more on the price. It weighs about a lbs and is the size of a regular smartphone, only a little thicker and less wider.
#3. RAVPower Portable Power Bank
This portable power bank and the two I mentioned previously share a lot of similarities, albeit there are a couple of noteworthy differences here as well. The biggest difference is the power level LED display. The display also shows the charging level when it is connected to a power socket.
Another noticeable difference here are the three output ports and two input ports. The three output ports include a USB 2.0 port, a USB 3.0 port with Qualcomm charging support and a USB type C port with 18w fast charging support. The input ports include a micro USB and a USB type C. So, in terms of connectivity, this one is off the hook.
I don’t know what is it with the manufacturers but even this one doesn’t come with a type C or a lightning cable. All you get a run-of-the-mill micro USB cable.
#4. EC Technology Portable Power Bank Ultra High Capacity 3 USB Output
Okay, I’ll start by saying, for the price, this is the most battery capacity you can get. Apart from that, it has a 2A port to charge the power bank itself. While the box says 2A is fast charging, it has certainly become a standard in most electronic devices and shouldn’t be confused with fast charging enabled.
The power bank is certified safe by the manufacturer and is capable of automatically disconnecting power, in case of over-charging or over-voltage. The safety certification also allows it to be carried between flights.
It doesn’t support Qualcomm charge but has the capability of fast charging multiple devices thanks to its three 5.5A USB output ports. You also get a 12-month manufacturer’s warranty, and two micro USB cables for charging the device. Oh yeah! It also has an LED flashlight.
#5. The PowerCore II from Anker
Another entrant from Anker, this is the newer version of their famous PowerCore. Apart from the many additional features, it also has a more expensive price tag which could feel a little steep to some.
Weighing a whole ounce less than its predecessor, the PowerCore II is also a lot less wider. It also has a little less capacity than the original PowerCore. 100mAh to be exact. It has two smart USB power output ports, 18w and 15w respectively.
Thanks to Anker’s new PowerIQ 2.0 technology, the power bank can be charged a 100% in just 5 hours. It also has power level indicator LEDs. The body is made of rugged plastic to provide a better grip in hands, and to keep it from slipping when placed on smoother surfaces. It can be bought in two colors, namely black and white.
#6. POWERADD EnergyCell Portable Power Bank
With its elegant physical appearance, compact size and 20000 mAh battery, the EnergyCell by POWERADD is geared toward the frequently traveling business people. The fact that it also meets all the international flying regulations also reaffirms this.
It has three ports, 2 USB and 1 USB type C which is 18w PD enabled for faster charging. The same type C port is also used for charging the power bank. It has a four LED power status indicator at the top. It has a chip installed in it that can automatically sense the charging current required for any device and adjust itself accordingly.
Unfortunately, the fast charging is only supported on the 18w PD port on the power bank. Also, if you wish to charge the power bank faster, you need to buy an 18w charger separately. The good news is, it comes with a 24-month warranty, a traveling pouch to carry it in, and a very favorable price tag.
#7. RAVPower Portable Power Bank – 16750mAh
Okay, so the last one on the list isn’t a 20000mAh power bank. Nonetheless, it is worth mentioning. RAVPower offers this one in four colors. Appearance-wise, it is more flatter and wider.
With its two power output USB ports, a 4.5A and 2.4A, this power bank is only suitable for smartphones and devices that are at least a year old. There’s no Qualcomm quick charge support here and neither is a USB type C port available. The power bank also takes up to 9 hours to fully charge, using a 2.4A power adapter.
This one also has a built-in LED flashlight and comes with two micro USB cables for charging the device and a pouch to carry it in. It isn’t very expensive but that reflects in its built quality.
How to Pick the Right 20,000mAh Power Bank for Your Gadgets – The Ultimate Buyer’s Guide
I hope you find all this information useful and make the right decision when purchasing a power bank for yourself. However, this list of best 20000mAh power banks will only be useful to you if you have some basic understanding of what you actually need. If you have no idea, this power bank buyer’s guide will help you out.
As I stated at the very beginning of this article, before you start searching for a power bank, you need to determine how much power you require. Take a look at the devices you travel with or you want to get the power bank for and add up their battery capacities to have an accurate answer. For most people, 20000mAh is more than enough.
The Number of Output Ports
Now that you have the capacity in mind, you need to create different scenarios to understand how many devices you would be charging, with that power bank, at once. Two output ports are more than enough for an average person. But you can also get power banks with up to four ports for convenience. Choose wisely!
Qualcomm Quick Charge Support
Many recently released smartphones, tablets, and laptops are supported for Qualcomm quick charge technology. While the majority of old, even flagship devices aren’t. Carefully research your devices and their capability of fast charging before jumping to a decision.
USB Type C Support
This one is connected to Qualcomm’s quick charge technology in a major way. Since Qualcomm’s quick charge is only supported on devices that have USB type C connectivity, deciding on this one shouldn’t be that difficult. To make it simpler, almost all flagship devices released after 2017 have type C support.
Apple Device Support
If you are looking to buy a power bank for one or all of your Apple devices, make sure the power bank you choose supports them. For some strange reason, certain power banks do not work with Apple devices. But this information can easily be found on the product description page or its packaging.
Acceptability on Flights
This one is really important. If you are a frequent flyer and your travels are one of the reasons for buying a power bank, you need to confirm that your chosen power bank conforms to all regulations related to carrying it in flight.
By now, I am hoping that I have helped you in reaching a good enough decision. If you do not have any defined specifics and just need a power bank to help you last through the day, or a week if you buy a 20000mAh one, always go for the cheapest option.
