Power banks that have very high power capacities can provide more than just a power capacity that can charge many devices multiple times over.

These kinds of power banks are also able to charge many devices at the same time and they can also charge larger devices like laptops.

However, as amazing as these kinds of portable chargers are, the “Portable” part of them isn’t exactly as portable as the word defines. Since they have larger power capacities and size capabilities, the equivalent exchange with all that power is that you get something that is large and heavy.

With that said, being large and heavy isn’t that bad when you have so much power that is utilized in such a great way. This Crave 50,000mAh power bank can achieve just that with its power, but the charging portion of the power bank is quite weak. Let’s take a closer look at this Charger Harbor Review.

Power Capacity:

Much like any other power bank on the market no matter how small or large they are, the power capacity that a power bank starts with isn’t what you’re going to receive.

This is because charging the power has to go through a conversion process through the batteries, circuitry, and then through the charging cable to your device.

In this case, the Crave power bank has an average conversion rate, and this is mostly attributed to its capability of Outputting 5 Amps all at once.

As a result, you’re most likely going to be able to charge 3 devices at once with the power bank, which is going to give you a 70% conversion rate. This means that you’ll be able to use about 35,000mAh of usable power. And that’s still a lot of power to use.

The Crave power bank is going to dominate when it comes to charging smartphones because you’ll be able to charge smartphones like the iPhone 6s Plus which has a 2,750mAh battery capacity about 13 times to full power. You can charge the new iPhone 7 18 times to its full power.

Even charging smartphones that are higher up on the battery spectrum such as a Samsung Galaxy S7 with this power bank, you’ll be able to get 11 full charges.

With all that said, just remember that we’re measuring full charges by charge a certain device alone with the Crave 50,000mAh power bank, and no other devices charging at the same time.

Output Charging:

There are quite a lot of options to charge using the Crave power bank.

USB Charging:

There are 4 USB charging ports, two of the USB charging ports have a charging speed of 5V/2.1A and the other 2 charging ports have a charging speed of 5V/1.0A.

5V/2.1A Charging Ports:

The two charging ports that have a charging speed of 2.1 Amps are the two that you should be using no matter what USB charging device you’re using.

This is because most devices will be able to charge at their fast charging speed with both of these ports. This goes for most smartphones, but this power bank does not feature Quick Charge and as a result, they won’t be able to charge at their max charging speed.

However, these two charging ports are very good for charging tablets as well because you’ll be able to charge most tablets at or at least near their max charging speeds.

5V/1.0A Charging Ports:

Both of these charging ports are the ones that are best to avoid because the charging speeds are slow. So the only reason that you’re going to use these charging ports is when you’re charging more than 2 USB charging devices and are forced into using these ports.

DC Charging:

There is 2 DC Output charging ports that are useful for larger devices like Laptops and Digital Camera.

20V/3A DC Output Port:

These DC charging ports is most useful for charging devices like Laptops and it’ll be able to charge most Laptops at their max charging speeds. With that said, the power bank cannot charge MacBooks because it does meet the charging power that MacBook use to charge.

12V/2.5A Charging Port:

This DC port Output lower power than the other charging port but it’s still very useful for charging lower power devices.

Overall Output Charging:

So there is some bad news that goes with this highly capable power bank, and that’s because the charger is only able to Output 5 Amps of power at once.

Once the power bank is Outputting over 5 Amps at once, then it will turn off. This is a safety feature to make sure that the power bank doesn’t overheat and damage itself. Even so, that’s quite a low Max Output that is only going to allow you to charge 3 devices at once at most.

Input Charging:

For a power bank that a power capacity of 50,000mAh, the charging speed is really good. It’s recharged through a DC Input port that can recharge the power bank at 16.8V/2.5A.

So the Crave portable charger can fully recharge within 7-8 hours. That’s not bad at all considering the power capacity of the power bank can last for weeks and all you have to do is recharge it for a couple of hours.

Design

Size and Weight:

With it having such a large power capacity, the size of the power bank is going to match it too. This is because it’s a large and heavy power bank that’s not meant to be held.

It has a length of 8 inches, a width of 6 inches, and thickness is 2 inches.

The weight of the power bank is 1 pound.

So it might be large and heavy, but that doesn’t mean that the Crave power bank is not portable. After all, it’s still a portable power. With that said, it’s still good to take when you’re at work, or the library because you can just set it down and charge your laptop and smartphone without being next to a Wall Outlet.

Also, it can be taken for camping trips or a hike into the outdoors and even though it’s heavy, placing it into your backpack will improve portability. With something that has so much power capacity, it’s very helpful to have long-lasting power.

Functional Components:

All of the functional parts of the power bank are on a single side of the charger.

On the side is where you’ll find:

• DC Input port
• 4 LED power capacity indicators
• the power button
• two DC Output ports
• 4 USB charging ports

You must press the power button to begin charging from the power bank.

Build

Structure and Material:

The entire Crave power bank is made of plastic but it’s still built very well, with the plastic being used is very thick. However, we recommend not dropping the power bank because it doesn’t have any shock absorbing properties that are going to save it.

Tech:

On the tech side, there’s quite a bit going on with the Crave power bank using a wide range of safety tech features to keep charging safely.

One of the most useful ones is the usage of Auto-ShutOff abilities. With the auto-ShutOff, once the Max Output capabilities of the power bank have been reached, then it turns off automatically. This can prevent damage to the power bank.

However, we found that it has a low Max Output that could have more potential in terms of getting more out of the power bank.

Reliability

This 50,000mAh Crave power bank is very useful for when you’re either charging USB chargeable devices and Laptops and when you want to charge them LOTS of times over.

It’s the power capacity that is the main attraction here because it can last very long and that means you can rely on a single full charge of the power bank for a long while.

Also, in addition to the charging ports that allow you to charge many devices at once, including Laptops, then we think that this power bank has flawless reliability.

With that said, there are still some unreliable traits that it holds. It’s a very large and heavy power bank that isn’t the best to carry around. Also, with its Max Output limit of 5 Amps all at once, the power bank can at most charge 3 devices at once which makes its other charging ports that aren’t be used, irrelevant.

Summary:

Power:

It has a very large power capacity and many charging ports. The power capacity is high enough that you can charge tablets, and smartphones lots of times over. You can get about 2 full charges for most smartphones. There are 4 USB charging ports.

Although the powering capabilities seem flawless, the power bank can only Output 5 Amps at once.

Design:

It’s large and heavy by nature because of its high power capacity. All of its usable parts are on a single side and you have to press the power button to begin charging.

Build:

Not the strongest structure but it’s still quite sturdy. Just don’t go dropping the power bank because that may very well damage it.

Reliability:

With its high power capacity and lots of charging options, for the most part, this Crave portable charger is very reliable. However, the Low Max Output of power can prove to be limited and so can the size and weight of it.

Even with all of its grandeur it still has its setbacks with not having a higher enough Max Output of power and it’s important to remember along with its high power capacity, also comes its large size and heavyweight.
