Portable charger these days are one of the most innovative charging electronics that you can own. It’s not only because you can charge your devices while you’re on the move, even though that’s basically the main reason that portable chargers are popular. But it’s also what comes with the portable charging that makes using a power bank a lot more worth it now.

Most portable chargers when they first came out usually would just have two regular USB-A ports used for charging a smartphone or a tablet.

Now power banks are capable of more than just that, and this iClever 21,000mAh goes to show that you can do more than just charge your smartphone. As this iClever portable charger feature USB-C Power Delivery, Quick Charge and it even has a Lightning input port. There’s quite a lot going on with this power bank, so let’s take a closer look to see if this is the best Power Delivery power bank that you should purchase.

Power

Power Capacity:

The power capacity of most Power Delivery portable chargers is very higher and that’s because when you use Power Delivery, the conversion of power from the power bank can actually lessen. As faster charging worsens the conversion of energy through the charging cable and increases in heat. In this case, this iClever portable charger does have a high power capacity, but it’s not on the same level as RAVPower’s 26,800mAh Power Delivery portable charger.

That said, let’s see just how much of its power capacity you’re actually able to use.

3.7 x 21,000 = 77,000 / 5 = 15,400

Enough Power Capacity?

Most of the time you’re going to be receiving a power capacity of 15,000mAh that you can actually use towards charging your devices. This is still a good amount of power capacity, we thought that it would better to have a higher one though. As the use of Power Delivery with this power bank means that you’re likely going to charge larger devices such as laptops that use USB-C. Such as the MacBook that now uses USB-C Power Delivery.

So if you’re charging laptops with this power banks, the power capacity can last you for about two full charges. That said, it’s really only that many charges if you’re charging just the laptop. As there is actually three output charging ports on this power bank. Something that we’ll get to in the output charging section.

Charging smartphones with this iClever power bank is able to offer a better experience with the portable charger and that’s because most smartphones these days have 3,000mAh batteries. So you charge them to full about 5 times with this power bank.

Overall, the power capacity of this charger is pretty good but at the same time, it’s not really enough to last for a few days. Especially if you’re charging multiple devices at once.

Output Charging:

Charging with his iClever power bank is the best part of it because it uses three Output charging ports.

USB-A Ports

There are two USB-A ports on this power bank. One USB-A port features Quick Charge 3.0, so it’s useful for charging Quick Charge compatible smartphones at their max charging speed. While the other port has a standard charging rate of 5V/2.4A.

It’s awesome that this power bank not only uses Power Delivery but another fast charging technology that those with compatible devices can use. At the same time, the use of Quick Charge is another reason that this power bank should have a higher power capacity as it’s also not good for converting power capacity for charging.

The standard port on this power bank also has a good charging speed, and you can also use Non-Compatible Quick Charge smartphones with the Quick Charge port and they will also charge at 5V/2.4A.

Quick Charge Speeds: 3.6V-6.5V/3A | 6.5V-9V/2A | 9V-12V/1.5A

USB-C Power Delivery Port

The USB-C port on this power bank is the main that you’re going to be purchasing this portable charger for in the first place. As the Power Delivery charging is able to output 30W of charging power. 30W of charging power is good and will charge your Power Delivery smartphones, tablets, and laptops at a fast charging speed.

At the same time, there are still power banks on the market that feature faster Power Delivery charging, such as iMuto’s Power Delivery portable charger that has 45W of Power Delivery charging. There is indeed Power Delivery compatible devices that are able to charge faster than 30W, such as MacBooks and Chromebooks too.

Power Delivery Charging Speed: 5V-9V/3A |12V/2.5A | 15V/2A | 20V/1.5A

Input Charging:

Recharging this power bank is what you should expect from the portable charger that uses Power Delivery and that would be the USB-C port also being used as an input for recharging. Not only that, but this power bank uses Power Delivery for recharging at 30W, too. That said, you’re going to need a USB-C Power Delivery wall charger to recharge it at Power Delivery speeds, and a USB-C charging cable which you might already own.

The one other input port on this power bank that we found to be quite cool, is the Lightning input. Most of the time when it comes to having two input ports, it’s always a Micro-USB and a USB-C. The use of a Lightning input is cool because this power bank is gearing itself towards those that own MacBooks that now uses USB-C. Another device that MacBook users may have are iPhones, so you can use your USB-A to Lightning cable to recharge this power bank through its Lightning input port.

That said, the Lightning input has a recharge rate of 5V/2.0A. Also, just something to know if you own an iPhone X or iPhone 8, is that you can recharge them at Power Delivery speeds, with the USB-C port by using a USB-C to Lightning charging cable.
