There are times when a portable charger needs to be more than just being able to provide power to us. These are called rugged power banks and they’re your best bet for charging your devices in a rough situation.

These kinds of portable chargers are built to take damage by the way they’re built. You may even consider purchasing these kinds of tough chargers for everyday reasons because they’re able to take falls fall, resist liquid, and can weather through dust every time it’s thrown their way.

So if you’re searching for chargers that can take what other normal and luxury power banks can’t, then it’s time to go the rugged route. In this review, we’ll be reviewing the EasyAcc 20,000mAh power bank to see if it’s deemed worthy to take into the outback and be treated as a tough piece of tech.

Power Capacity:

A Long-Lasting Power Capacity

Rugged power banks usually have high power capacities because they’re expected to be taken into the wilderness where there’s no chance that you’ll be able to charge any of your devices.

This is true with this charger because it boasts a 20,000mAh power capacity. Of course, the real Output power capacity that you’ll be receiving will be lower due to power being lost during charging. The power bank doesn’t have the fastest charging, but it’s still going depend on how fast the device you’re charging is going at.

With that said, the two ports are rated at 5V/2.4A for one port and 5V/1.0 for the other one; with a  total output of 3.4A. So if you’re going all out with this charger, you can expect a power capacity of 15,000mAh. Using only a single port can leave you with even more, which is 18,000mAh.

The truth is that you’re NOT going to receive the full 20,000mAh power capacity, but that’s okay since even the depleted amount is quite enough to last you days.

That’s right, the power capacity is high enough to charge smartphones like the iPhone 6s 10 times over, the iPhone 7 can be charged 9 times over and smartphones with behemoth battery capacities can charge 6 times over.

For tablets, you can expect 1.5 charges for many, because a charging speed for many tablets is 5V/2.4A and as a result, more power capacity will be lost during charging.

Although there can be cases that tablet can charge 2 full times but we don’t recommend charge a tablet with this power bank if you’re out in the wilderness because it’ll take up the most or entirety of the power.

With all that said, the power capacity can very well last you for days even if you’re using it constantly to charge your smartphone. If you’re using it moderately, and aren’t in the wilderness, then it can potentially last for weeks without needing to be recharged.

Output Charging:     Port 1 – 5V/2.4A       Port 2 – 5V/1.0A      Total Output – 3.4A

This rugged charger takes the usual path when it comes to charging speed with one port being able to deliver a max standard charging rate of 5V/2.4A and the other can deliver a slower charge 5V/1.0A. The logic here is that you’d use the 2.4A port for devices like a tablet and the 1.0A port for smartphones.

However, as we mentioned, you don’t want to use a tablet with this power bank if you’re really deep into the woods and far away from civilization. Instead, if you’re solely using a smartphone to use with this charger, then you should always use the 2.4A port.

This is because the 2.4A port will be able to charge the smartphone at its max charging speed. Except for Quick Charge compatible devices since this power bank does not feature Quick Charge tech.

If you are charging a tablet with the 2.4A port, then you’d use the 1.0A port for a smartphone.

Input Charging:    Micro-USB-5V/2.0A

Although it’s quite a bummer that this high capacity rugged power bank doesn’t feature 2 Micro-USB ports, it does well with just one. The Micro-USB input is used to recharge the power bank charger at 5V/2.0A speed. However, to charge it at 2 Amps, you’re going to need to use a 2 Amp wall charger or beyond.

Using a lower Amp wall charger will result in a slower recharging rate. So if you’re recharging the power bank at 2 Amps, then you can expect it to be fully recharged in 12 hours.

Size and Weight

One of the most important aspects of a rugged charger is how you can use it. So of course, as mentioned, this power bank has a large power capacity and is quite big. The length is 6.3 inches, a width of 3.5 inches, and a thickness of 1.1 inches.

It weighs a heavy 1.2 pounds. So if you’re taking it into the outback and want to travel light, this isn’t the best choice but you can always put it into your backpack. Holding it in your hand isn’t a good option because the power bank is large and heavy.

Also, you can’t connect it to a carabiner since it doesn’t have any hooks. That was the biggest disappointment, though, you can’t latch it onto anywhere for easy access instead this charger has to go into a container.

The power bank does have great design structures, though if you’re holding it because it has many ridges and grooves that make a strong grip while you’re holding it. All the charging ports can be covered by a plastic flap to make the power bank waterproof.

Under the flap, you’ll find the two USB charging output ports and the Micro-USB Input port in between them. The power bank comes with a flashlight that is always fully exposed and can be turned on via the power button on top of the power bank.


By doubling click the power button, the flashlight turns on, press it again and it goes in flash mode, and by pressing it one more time it blinks like an SOS light. You can also, use the power button to turn the power bank on for charging (Of course) and for checking the power capacity of the power bank through the 4 LED lights on top of the charger.

The charger turns off when nothing is connected to it for more than 30 seconds as a safety precaution. Also, if all the devices that you’re charging are at full, the power bank will shut off then too. Unfortunately, it does not begin charging when you connect a device to it.

It’s a well-designed power bank that’s simple to use but the lack of anything to hook with it is a limit. Because its large size isn’t ideal to carry in your hand and putting it into a backpack is a little too distant from the user.

The Best Part of this Rugged Power Bank

This where the EasyAcc rugged power bank can excel. The charger’s overall body material is made of plastic but plenty of metal screws to make all the structure points hold strong.

As a result, the charger is shock-resistant, so if you’re going biking and decide to put it into your pouch then it’ll be fine. The other two safety points of the rugged charger are it’s also Waterproof and Dustproof.

However, the power bank can only withstand water and dust if the flap cover is put over the charging ports because everything except for the charging ports can let water get it in.

So just to be clear, if you have the flap open, and it’s charging a device, and it falls into water or maybe the charging ports get water on them. Then there’s a very high chance the power bank will be damaged.

It Can go for a Swim

So it’s very tough when you’re not using the charger itself and has an Enclosure rating of IP-67 when the flap is closed which means that its dust-tight and protected against water immersion.

This does mean that this charger can go swimming and not get damaged with charging ports being covered up. However, when the flap cover does come off, the power bank can only be rated as shock-resistant, although the ports are depressed into the body of the charger, so there’s that.


As for the inner safety tech, the tough power bank has all the certification to prove its worth of physical and tech quality; with its CE, FCC, and RoHS certifications. The safety tech can prevent a short-circuit, over-discharging, and over-charging of your devices which is why it shuts off.


From the physical structure of the tough power that it’s able to deliver, of course, this charger can withstand many physical tribulations thrown at it. The power capacity, if used correctly can be ideal for situations where there isn’t a stable source of power.

Although you won’t receive the full power capacity, you’ll still be able to get most of it with about 15,000mAh to 18,000mAh of power.

The charging speed is good but to make both the power capacity and charging speed worth it, we recommend only using smartphones or other devices that require lower Amperage speeds to charge. Using a tablet with this power bank will result in a fast depletion of its power capacity.

Then there’s the build, which is what this waterproof power bank was made for. It’s a portable charger that’s meant to be taken into the woods either for camping, hiking or you can even take it for canoeing. It’s shock-resistant and can be waterproof and dust-tight.

The keyword there is “Can” because it can only be fully safe from water and dust if you keep the charging ports covered. By doing so, the power bank’s Enclosure rating is with an IP-67 rating.

The Output power capacity is going to be lower than 20,000mAh but even so, just how much lower it will depend on how you use it. Charging it with smartphones is the best way to take advantage of most of the power bank, charging a tablet can take nearly all the power.

So use the 2.4A port with your smartphone but if you’re charging a tablet, you’d use the 2.4A port. It has a max output of 3.4A so not bad. For places where you won’t have power for days, this will be able to last for days.


The design could have used some work with an ability to latched onto something such as a carabiner. Without it, you have to settle with placing it into a bag or holding it. Either of those gives a mediocre experience with using it. However, the ridges on the body make it easy to hold.


The strongest point of this rugged power bank. It’s shockproof with its strong body that’s held together by screws. The power bank can even be waterproof and dust-tight with an Enclosure rating of IP67. However, it’s only possible with the flap covering the charging ports.


The reliability lies with just how tough and long-lasting this power bank is. It can be immersed in water and it can last for days if you’re without power. So it’s a reliable power bank if used correctly.

However, the lack of a place to latch it onto is quite disconcerting because this means that you have to place it in a bag or your hand.
