Power banks have come a long way, from what they feature such as fast charging, the power capacities that they hold, and the form factors that they take. Many power banks on the market are on par with each other, as most of them feature some sort of fast charging such as Power Delivery or Quick Charge, the sizes for them also match.

However, for this Silicon Power QP70 power bank, it’s a little different. This QP70 10,000mAh portable charger is tiny it’s so small that you would mistake it for a 3,000mAh mini power bank, and the better part about this Silicon Power charger is that it features Quick Charge and Power Delivery.


Power Capacity:

This charger has a 10,000mAh power capacity, so you’re looking at a power capacity that can charge most smartphones to full power about one or two times. This is due to most smartphones now using larger batteries such as most Samsung Galaxy phones have 4,000mAh batteries. Also, iPhones, the smartphone that usually has a smaller battery has been upgrading its battery every year, as the iPhone 12 Pro Max has quite a large battery of 3,687mAh.

Charging tablets with this power bank is possible, and you may want to because of its fast charging, but if you’re looking to charge a tablet to full power then you’re looking at using the full power capacity that this power bank has.

Output Charging:

Charging from this QP70 portable charger is great. There are two output charging ports, with an 18W Power Delivery port and a Quick Charge 3.0 port.

The USB-C Power Delivery port is more of the universal fast charging port on this power bank, as you’re able to fast charge most Android smartphones with the USB-C port. You are also able to fast charge newer iPhone models with the USB-C PD port when you use a Lightning to USB-C cable.

The USB-A Quick Charge 3.0 port can fast charge Quick Charge compatible Android smartphones, and it can also fast charge Non-Quick Charge compatible devices, too.

Also, we know that there are many USB-C Power Delivery compatible laptops, but an 18W Power Delivery port is not powerful enough to charge most USB-C PD laptops as it’s not enough charging power.

Input Charging:

Recharging this power bank is as fast as the output charging. This is because you’re able to recharge using the USB-C Power Delivery port, therefore you’re able to recharge at Power Delivery speeds via a PD wall charger. You may also use the Micro-USB input port to recharge the power bank and you can recharge the power bank at Quick Charge speeds with a Quick Charge 3.0 wall charger.


Size and Weight:

As we said at the beginning of this review, this is a tiny power bank. The charger has a length of 3.4 inches, a width of 2.3 inches, and a thickness of 0.8 inches. The weight of this charger is 7 ounces. It doesn’t matter if you’ve got the smallest hands on the planet, this is a very small power bank you’re able to hold in your hands with ease.

Fitting it into a pocket is also a great option.

Functional Components:

The charger has all of its charging ports on a single side, the power button can be found on the long length side, and then there are four power indicators on the opposite side. Charging automatically starts when you plug a device into the charger, and if you’re fast charging, then one of the power capacity indicators turns green to show that your device is fast charging via Quick Charge or Power Delivery.


Structure and Material:

The build quality of this power bank is strong. Since it has such a compact size, all of the materials are closer together and the charger has less of a chance of breaking apart if it were to drop.


Since the charge has such a small size, we thought that it would get warm or even hot during charging. That’s not the case here, as the charger doesn’t even warm up when fast charging through the Power Delivery or Quick Charge port.


This is one of the most compact fast charging mini 10,000mAh power banks that you can purchase. The first thing to know is that the charger is very small, one of the smallest 10,000mAh power banks that you will find. To add to that, it features Power Delivery and Quick Charge fast charging for fast charging your own devices and also for fast recharging the power bank itself.

The charger comes with a USB-C to USB-A cable and a carrying pouch.

This charger is not so reliable for charging laptops, as the Power Delivery is not powerful enough.



There is enough power capacity for charging most smartphones to full power about once or twice. Features Power Delivery and Quick Charge for output and input charging.


Very small, is the size of a 3,000mAh power bank.


The charger has a strong compact build, and it does not heat up even if when fast charging.


This is one of the most compact fast charging power banks that you can find on the market that is best used for smartphones.
