Being able to charge a laptop with a power bank is somewhat a recent ability, and this is due to laptops being compatible to use USB-C Power Delivery charging. A more universal way of charging our portable devices as it’s not only usable for smartphones, but also for charging laptops because of how powerful it can be.

Power banks that do use Power Delivery can usually be placed into two categories and that would be PD power banks that are useful for charging smartphones, and ones that can charge phones and laptops.

This RAVPower RB-PB159 20,100mAh Power Delivery power bank is a perfect one that can be useful for charging USB-C PD laptops, as well as charging your smartphone.

Power Capacity:

The power capacity of this power bank is 20,100mAh. A good amount of power capacity for charging smartphones and also charging laptops.

When it comes to charging laptops with a 20,100mAh power capacity you’re going to average about four full charges for most smartphones. You might think that you’re able to get more because a 20,100mAh capacity sounds like a lot, but you also have to consider that many phones these days have larger batteries and they use more power.

The Samsung Galaxy S20 Ultra has a 5,000mAh battery, that’s a large battery and in this case, the S20 Ultra would only be able to charge from this RAVPower portable charger about three times only. You’re not able to use the full 20,100mAh capacity because some power is lost during charging, and especially if you’re using the PD charging you can expect about a 4,000mAh power loss during charging.

However, for the most part, many smartphones have 4,000mAh batteries, and this means you are able to get about four full charges for many iPhones and Android smartphones.

When it comes to charging laptops with a 20,100mAh power capacity, you’re going to get a similar charging experience as you would with phones. This is because most laptops also have 5,000mAh batteries or a bit higher than that. At least that’s what most USB-C MacBooks now use, and the same can be said about Chromebooks.

That said, the main difference when it comes to charging laptops is that laptops use more power, and more power is being used even if you’re charging. So you should expect about two full charges for a laptop with this RAVPower portable charger, which is pretty good because you’re looking at two full days use of this power bank without having to recharge it.

Output Charging:

The output charging is done with two ports, and that would be a USB-A port and a USB-C Power Delivery port.

The USB-A port is the less impressive of the two ports and is not the reason that you’d get this power bank. This is because the USB-A port has a standard charging speed of 5V/2.4A. So you won’t be fast charging any smartphones with this port, but it is mostly just meant of charging smartphones.

On the other hand the, USB-C Power Delivery which has a 45W charging speed is the reason to get this power bank. Most Power Delivery power banks have a 30W charging speed from their PD ports. At the same time many USB-C PD compatible laptops can charge faster than 30W, so this 45W Power Delivery port can charge them faster.

Also, even with a 45W PD output, you can still use the Power Delivery port for fast charging Android smartphones that use USB-C ports, as most are Power Delivery compatible. At the same time, you may also fast charge an iPhone with a Lightning to USB-C cable with the Power Delivery port.

However, just know that the PD charging speed for smartphones will be capped at 18W, and not 45W.

Input Charging:

The recharging for this RAVPower power bank can be done with one of two ports. You can either use the Micro-USB input port or the USB-C Power Delivery port. The Micro-USB input port has an 18W max recharging speed, and the USB-C PD port can recharge the power bank at a 30W charging rate.

For recharging the power bank at 18W with the Micro-USB input port you have to use a Quick Charge wall charger. To fast recharge at 30W with the PD port you have to use a 30W PD wall charger or higher.

The good news is that this power bank comes with a USB-C to USB-C cable, and a Micro-USB to USB-A cable. However, it does not come with a Quick Charge or Power Delivery wall charger.


Size and Weight:

The size of this power bank is nothing to be worried about. You are going to be able to place this charger into your pocket. The charger has a length of 6.3 inches, a width of 3.1 inches, and a thickness of 0.9 inches. The weight of the power bank is 14 ounces.

So it’s about the same size of a mid-range 10,000mAh power capacity, except, you have more power to use and more powerful charging with the Power Delivery port.

Functional Components:

Despite using a faster charging speed, and higher power capacity, it’s as simple to use this power bank like any other one. There is no need to press the power button because charging automatically does start most of the time when you connect a device to a port. There is a power button that turns on the four power capacity indicators.


Structure and Material:

The build quality of this power bank is on par with what you can expect from RAVPower’s brand, and that would be a solid product that will last you a long time. The charger is built well without any cheaply made parts and is perfect for daily use.


Even though the power bank can output 45W, that’s the limit. If you’re charging two devices at the same team, such as charging one device with the USB-A port and one with the USB-A port, then the USB-C PD port will only output 30W.

The Power Delivery port will only output 45W if that’s the only port you’re charging from. Even with its 45W PD port the power bank does not overheat.


Power Bank comes with a Micro-USB and USB-C cable

The reliability of this power bank is great for charging either USB-C Power Delivery laptops or smartphones. It’s great for charging laptops because of its higher 45W charging rate that many laptops can charge faster from. At the same time, the PD port can still fast charge many PD compatible smartphones at 18W.

To make things more reliable, the power bank is also easier to use out of the box because it includes a USB-C to USB-C cable and a Micro-USB to USB cable.



There is enough power capacity for charging smartphones and laptops to full power a few times. The more impressive part is that the power bank can charge at a 45W Power Delivery speed and recharge at 30W with the PD port.


The charger is easy to use with automatic charging and a small form factor that can easily be placed into a pocket.


The build of the charger is great for daily use, and it doesn’t overheat even with its 45W PD charging speed.


This is very reliable power for USB-C PD laptops because it allows you to charge many PD compatible laptops at a faster charging speed that would otherwise charge slower with a 30W PD power bank. The charger is also usable out of the box because it comes with a USB-C to USB-C cable and a Micro-USB to USB-A cable.
