Power banks have improved quickly over the past few years, as we now have power banks capable of outputting 30W of Power Delivery while having the size of a 5,000mAh or 10,000mAh power bank. This innovation makes it possible to charge laptops with a portable charger that can fit into your pocket; this was not possible a few years ago.

To add to the advancement of charging power and smaller form factors, the style of portable chargers has also changed the most, having some design cue that makes them look unique. In this review, we’re taking a look at this TEGIC BLOCK 30 Power Delivery power bank; this charger has a prominent design that shows the inner circuitry of the charger, something no other power bank features. It also has powerful PD charging while being the same size as a smartphone.


Power Capacity:

The power capacity of this TEGIC power bank is nothing too impressive as it has a 10,000mAh power capacity. So you’re going to average about two full charges for some smartphones, or you may very well only get a single full charge for some phones; that’s because if you’re using fast charging, then the conversion of power is less efficient, and you end up with less power actually to use. The packaging says that if you’re using 5V/2.0A output, then the rated capacity is 6,500mAh.

As a result, if you’re using fast charging such as Power Delivery or Quick Charge, then you’re going to end up using about a 5,000mAh power capacity from this power bank.

These days, most modern phones have large batteries, take, for example, the Samsung Galaxy S21 with its 5,000mAh battery, or the Galaxy Note 20 with a 4,300mAh battery, and the iPhone 12 Pro Max a 3,687mAh battery. This TEGIC power bank can get these phones to full power at least once, but the charger will not have much power left over if at all.

That said, this is not a bad thing, as recharging modern phones to full power gives you another full day’s use, and this full recharge can span into the next day.

Charging laptops with this power bank is possible, too, as the power bank has a powerful USB-C PD port. You can come close to charging a laptop to full power. Getting it to actually 100% is unlikely because of the higher charge rate that you’ll be using.

Output Charging:

Easily one of the best parts of this TEGIC power bank is the charging you get from it. The power bank has a 30W USB-C Power Delivery port and an 18W USB-A Quick Charge port. With the USB-A port, we charged a Samsung Galaxy S10, a Quick Charge compatible Android phone, and it was able to fast charge the Galaxy S10.

Then we switch over to using the USB-C Power Delivery port, and we used it to charge a Microsoft Surface Go tablet that can charge via USB-C PD. The tablet could charge from 15W to 20W, which is the tablet’s max charging speed.

With a 30W Power Delivery charge rate, you’re also able to charge quite a few USB-C laptops such as Macbooks and Chromebooks; however, that’s where we’d draw the line. Many USB-C laptops on the market require higher PD charging speeds actually to charge from a USB-C port, and we don’t want you to be disappointed that this power bank can’t charge your laptop because it requires more than 30W to actually charge.

Macbooks and Chromebooks are known to charge easily no matter what PD rate you’re using, so it’s safe to charge them with this TEGIC power bank.

Input Charging:

Recharging this TEGIC power bank is just as good as the output charging because it has a 30W input. You have to use a 30W PD wall charger to recharge it at its max charging speed, and doing so will get it to full power very quickly. The power bank does not come with a wall charger.


Size and Weight:

The power bank is not large. It has a length of 5.3 inches, a width of 2.5 inches, and a thickness of 0.6 inches. The weight of the charger is 8 ounces, so it does have a bit of weight, but it’s not heavy. The charger is the same size as a smartphone.

Functional Components:

Included in the box is a cable USB-C to USB-A cable that can be turned into a USB-C to USB-C cable because the USB-A port of the cable can come off and reveals a USB-C connector, therefore turning the cable into USB-C to USB-C. This allows you to use the two ports right out of the box on this power bank.

The two ports on his power bank are on the same side, and there’s a power button that you can press to check the power capacity level, and charging automatically starts. The most notable part of the TEGIC power bank design is the Tempered Glass window that shows the charger’s circuitry.

You can see the power capacity indicators through the window, and there’s also an Orange LED that turns on when you’re using fast charging. We’ve never seen a power bank with such a design that lets you see the inside of it, but we’re glad that TEGIC is the first to release a power bank that looks incredible as this one.


Structure and Material:

The side and top of the power bank are made of Aluminum Alloy, while the bottom of the power bank is made of a rubber material; this gives more grip to the power bank. It truly does feel premium. If you’re working about the Tempered glass possibly breaking, don’t be. The only way that it’s breaking is if you’re intentionally hitting it with a hammer or if it falls on hard flooring from a high height; either of those actions would break any power bank.


There isn’t anything to worry about when it comes to the tech of this power bank, at least, in our experience. We charged the Surface Go, which took advantage of nearly the full power of this power bank, and there were no overheating issues, and the charging worked perfectly fine.


The charger is very reliable if you’re looking to fast charge your smartphone wherever you are, and you have a USB-C laptop such as a Macbook or Chromebook that can also be charged with this TEGIC power bank. This power bank is not meant to be relied on for days on end as it only has a 10,000mAh power capacity, and it has a 30W Power Delivery charging speed, so it can’t charge all USB-C PD compatible laptops.

However, the fact that it can output 30W while still being a 10,000mAh power bank is impressive.



A 10,000mAh power capacity that can charge most phones to full power either once or twice. It also has Quick Charge and a 30W USB-C Power Delivery charging speed from the USB-C port that can be used to fast charge phones, and it can charge laptops.


The charger is the same size as a phone, and it weighs 8 ounces. The most important of the power bank’s design is the Tempered glass that lets you see through the power bank to look at the internals.


The charger has a great build, with it being made of Aluminum on one side and a rubber material on the other side; this prevents the power bank from sliding around on surfaces.


The TEGIC power bank is reliable for smartphones users and some USB-C laptop owners, as a 30W Power Delivery charging speed can only get you so far with charging certain laptops.
