If you’re going to purchase a portable charger, there’s a high chance that the one you’re getting is gong to feature either Quick Charge or Power Delivery. This is because most portable devices are compatible to charge using either of those technologies.
In this review, we’re going to be taking a look at a UGREEN PB166 20,000mAh 18W Power Delivery and Quick Charge power bank. The charger has the best of both worlds when it comes to its charging, and it has quite a high power capacity, but let’s take a closer look to see what you’re able to do with this power.
The power capacity of this UGREEN power bank is 20,000mAh, and this much power capacity is what really should be the standard for most people purchasing a portable charger. That’s because most portable devices now have larger batteries, as most smartphones are already at or near using a 5,000mAh battery.
As a result, using a 10,000mAh and a 5,000mAh power bank may result in an only single charge for most smartphones and tablets.
With this 20,000mAh power capacity from this UGREEN power bank, you ‘re going to fair about two to three full charges for most smartphones on the market. This going to be the case for the Samsung Galaxy S20, S20+, and the S20 Ultra. All of which have a 4,000mAh, 4,500mAh, and a 5,000mAh battery.
So you won’t have to recharge the power bank for a day or possibly three days depending on how much you’re using it.
As we mentioned at the beginning of this review, this UGREEN power bank has an 18W USB-C Power Delivery port and a Quick Charge 3.0 USB-A port. That’s it. Of course, you can charge Non-compatible Quick Charge or Power Delivery devices with the ports, but the point of purchasing this power bank is to take advantage of the fast charging.
Alright, so the first thing to know is that the USB-C Power Delivery port on this power bank does not have enough charging power for laptops. We tested it with a Lenovo Flex 5 laptop which is a Power Delivery compatible laptop. The charging for the Flex 5 laptop constantly just started and stop, likely because 18W of PD charging is enough to charge the laptop.
However, for laptops and smartphones, the 18W Power Delivery port is perfect. Another factor of this power bank to know is that you can only take advantage of the fast charging from either port is if you’re only charging from a single port at a time.
In our case, we tested this power bank with a Samsung Galaxy Note 9 and a Microsoft Surface Go. We plugged in the Surface Go with the Power Delivery port, and it was charging at a 13W to 14W with higher Voltage, so basically taking advantage of the 18W PD charging.
Then we connected an LG G7 to the USB-A Quick Charge port, and the charging speed for the Surface Go dropped to 5W and the LG G7 charging speed was standard and not fast charging.
We then disconnected the Surface Go from the Power Delivery port, and LG G7went from standard charging to fast charging. This happened because when using both ports at the same time the max output of this power bank is 15W.
The only port that you can use to recharge the power bank is the USB-C Power Delivery port, and the good news is that you’re able to recharge the power bank at 18W Power Delivery speeds. However, you will need a Power Delivery wall charger, but this power bank does not come with one.
Size and Weight:
The power bank is quite small, of course, it’s going to be larger than, say, a 10,000mAh power bank, but even this 20,000mAh power bank should not be giving you much trouble at all with portability. The charger has a length of 6.2 inches, a width of 3.7 inches, and a thickness of 1.2 inches. The weight of this power bank is 1 pound.
On the weight side, it is somewhat heavy but other than that, it’s a portable enough charger that you can place it into your pocket, or just holding it in your hand is easy enough, too.
This UGREEN power bank is all about minimalism. There is an indented power button off to the side of the power bank, the two charging ports are next to each other, and there is a digital power capacity display. Charging automatically starts, but you can press the power button to restart charging or to check the power capacity of the power bank.
Overall, we love the design of this charger, even though it’s made of plastic, it has a threaded design and the lack of a noticeable power button or lights is a welcome addition.
Structure and Material:
The build quality of this power bank is great, and it’s nearly a unibody power bank expect for the two black side panels. It’s not a shockproof or water-resistant power bank, but it has a great build that can last for a long time if you treat it right.
Even with it featuring Power Delivery and Quick Charge, the power bank does not heat up. This is because even when you’re charging two devices at the same time, the max output is 15W. If you’re charging only a single device, then the max output of the power bank can only be 18W.
This is a very reliable power bank for most smartphones and tablets, so long as they are either Power Delivery or Quick Charge compatible. This is not a reliable power bank to use for Power Delivery compatible laptops, as an 18W PD port is not enough charging power.
Another unreliable part is that you can only fast charge from a single port at a time because the max output of the power bank is 15W.
It has an 18W Power Delivery port and a Quick Charge port for fast charging compatible devices. You’re also able to recharge the power bank at Power Delivery speeds. You can only fast charge a single device at a time, as the max output of the power bank is 15W when charging two devices at once.
The charger is quite small, a bit heavy at 1 pound, but it’s easy to use with charging automatically starting.
The charger does not overheat as the max output of the power bank is only 15W.
It’s a reliable power bank for Power Delivery smartphones and tablets, such as how we charged a Microsoft Surface Go and a Samsung Galaxy Note 9. The unreliable part is that you can only use the max power of each port only once at a time.

This UGREEN PB166 Power Delivery and Quick Charge 20,000mAh power bank hits the right marks with its fast charging, and great design. It even includes a USB-C to USB-A cable. It would be even better if you could use both the ports at their max power at the same time, to fast charge a tablet and your smartphone, though.
