Even though there are a lot of rugged power banks on the market, most of them are have certain standards of what they can take. In terms of taking shock damage in the event of a fall, nearly all rugged power banks are able to take a fall.

With that said, the water resistant part of a rugged power bank is what varies. This is because some power banks have different enclosure levels, and as a result, some portable chargers are able to just take withstand a splash water, some can take powerful jets of water and only a few can actually be immersed into water.

With that said, the amazing part of this Dark Energy Poseidon power bank is that it has a very rare attribute to it, and that’s the fact that it can be immersed into water constantly because it has very good Enclosure level of IP68.

Power Capacity:

This Dark Energy Poseidon power bank has a power capacity of 10,000mAh and when it goes through its average conversion rate of about 70%, there’s going to be enough power capacity to charge smartphones multiple times.

If you’re charging two devices at the time, then the conversion may be worse, though. With that said, you’re going to be receiving about 7,000mAh of usable power capacity.

Poseidon for Smartphones

It’s with 7,000mAh that you’ll be able to charge most smartphones 3-4 times to their full power.

With that said, if you own some newer smartphones that have power capacities of 2,500mAh or 3,000mAh, then this Poseidon power bank will still hold up quite well because it can deliver about 2.5 full charges to a Galaxy S7 or an iPhone 7 Plus.

If you own a smartphone with a battery capacity of 2,000mAh or lower, then you can about 4-6 full charges.

Poseidon for Tablets

For the most part, this Rugged power bank is meant to charge smartphones and other smaller devices that have similar power capacities to that of smartphones. This is because if you’re charging larger sized devices like tablets, then it won’t do too well.

Since even mini tablets like an iPad Mini 2 or iPad Mini 4 are going to be able to charge to their full power once and barely even leave any power capacity left to use.

So you can charge a tablet to its full power, but after doing so, you need to realize that there won’t be a lot of power capacity left to use.

Output Charging:

The Dark Energy Poseidon power bank uses two charging ports. One of the charging ports has a charging speed of 5V/2.4A and the other one has a charging speed of 5V/1.0A.

Using the 2.4A port should be the primary port that you should always use because it’s going to give the faster charging speed for any device you choose to charge the power bank. Since most devices are able to charge faster than 1 amp and also the 2.4A port is able to charge tablets like iPads at their max charging speed of 2.4A.

Then the 1.0A port should only be used when you’re charging 2 devices at once because it gives a slower charging speed.

Altogether, even though have two charging ports have their own set charging speed is a flaw, because you’re always going to have a port with slow charging. You can still use both of the charging ports at their full potential because the power bank is capable of having a max output of 3.4A.

Input Charging:

The power bank uses a Micro-USB Input port to recharge and it has a max recharge rate of 5V/2.0A. So using a 2 Amp wall charger will provide the fastest recharge rate and will result in a full recharge time of 5-6 hours.

Size and Weight:

It’s not too large of a power bank and that’s mostly because it doesn’t have too high of a power capacity and all the safety is slimmer lined on the power bank. It makes it easier to have more portability with the power bank.

Not too large of a Rugged power bank

It has a length of 6 inches, a width of 3.5 inches, and a thickness of 0.8 inches. The weight of the power bank is 11.2 ounces. So it’s quite small, and can be held in your hand because it’s also somewhat lightweight. However, it does have a lanyard hole at the end of it and that makes it possible to place the power bank onto a backpack,

Functional Components:

Most of the functional parts of the power bank can be found under the waterproof covering. Under the cover is where you can find two USB charging ports, a Micro-USB Input port, and a LED flashlight.

On the top of the power bank is where there are 4 Green LED power capacity indicators, and to the long side of the charger is the power button.

Charging automatically starts when you connect a device into the power bank. So the main usage of the power button is turn on the flashlight by holding it down, and you can press it again to change it from a Constant version to an SOS version. Also, you can just press the power button once to check the power capacity.

At one end of the power bank is where you can use a rope or use a carabiner with the power bank, which allows you to latch the power bank onto a backpack for those times when you’re camping, hiking or biking.


Structure and Material:

The strongest point of the power bank.

It’s covered in reinforcement from plastic to aluminum that makes the power bank able to withstand falls onto the hard ground.

Even though it’s great that it can take falls because that is a likely occurrence in our everyday lives and out in the wild, there’s something this power bank does that not many other rugged power banks do. It’s the fact that it has an Enclosure rating of IP68, which means that it can withstand constant immersion into water.

Which is why Fishing is one main activity that you should highly consider taking this power bank for.


On the tech side, the Poseidon power bank does have the necessary safety tech feature to make sure that you and your devices are safe during charging.

With its small size and ability to take on shock and any water threats this power rugged power bank cannot only be reliable in the wild but also in our everyday lives.

The power capacity is high enough charge most smartphones multiple times, and it also has two charging ports. Then there’s the use of a lanyard hole as well that makes portability very easy if you’ve got a backpack.

This power bank does so many things right and that’s what makes it so reliable.

The power capacity is enough to be used for smartphones but not exactly for larger devices like tablets. The use of 2 charging ports is welcomed but you’re going to want to always use the 2.4A port at all times.


It’s quite small and easy to use. The flashlight can be quite helpful if you’re out camping at night. The lanyard is going to be very helpful for portability.


The name of the power bank certainly matches what the Poseidon power bank is capable of because it can be constantly immersed into the water without taking damage.


Just know that you can get quite a lot of charges for smartphones, but it may or may not be enough power for a full week. Other than that, the power, design and strong build make this a power bank that can be used for everyday life or when you’re in the wild frontier.
