Review: ROMOSS PEA30 30,000mAh 30W Power Delivery Power Bank. Power bank 30w

Tegic BLOCK 30 review: A sleek 30W fast charging power bank for your inner geek

Power banks are a dime a dozen these days. With the number of portable electronic devices we use, they’re almost a must-have depending on where we are. For the most part, they all look similar with a pretty basic and boring design. However, there are a few that that come along with a bit of a unique look.

What’s included with the Tegic BLOCK 30 power bank.


When the Tegic BLOCK 30 power bank arrived, and I took it out of the shipping box, the first thing I noticed was the paper clamshell packaging it was in. Ivory in colour, a simple black sticker held it shut. At first, I thought it was a bit cheap-looking but then realized that the company is trying to do its part for the environment by using degradable packaging. Opening up the box, I was greeted to the power bank nestled snugly inside — and the sleek look of the power bank actually looked at home in the packaging. That said, the power bank was wrapped in plastic which — given the packaging — wasn’t necessary and kind of offsets the eco-friendly nature of the clamshell.

The BLOCK 30 power bank itself has a bit of weight, expected given its aluminum CNC design. The top and sides of our review sample were a gunmetal grey colour, while the bottom is a soft rubber-like material. The device is just over 2 1/2″ in width, 5 3/8″ in length, and about 5/8″ thick. Aside from the quality looking finish and feel of the power bank, the top portion has a tempered glass window roughly 1″ by 2 1/2″ under which you can see some circuitry. There are also five exposed LED lights, and the words BLOCK 30 are printed in gold on one side. The Tegic logo is printed on the bottom of the top of the power bank as well.

The long edges are pretty bare, except for the words 30W PPS on the right side and 10AH 37WH on the left side. Both of these are printed in silver and sit beneath a small tempered glass cover. The top short edge is where your ports are. On the far left is a button, slightly off-center is the USB-C port (output/input), and on the far right is a USB-A port (output).

Also included is a relatively short USB-C to USB-A cable — roughly 7 1/2″ in length. I didn’t realize it at first, but the USB-A end is actually a cap. When removed (don’t worry about losing it as it remains attached to the main cable), it exposes a USB-C connector. While it could be a tad longer, this single cable lets you charge both USB-C and USB-A devices.

One item that is notably missing from the Tegic BLOCK 30 is a cloth pouch. Even a simple thin pouch would be nice, as I’d worry about the glass window getting damaged and shattering on the inside of your bag, depending on how you transport it. It’s not a huge issue, but you will have to be cognizant of what or pouch you place it in when travelling to avoid any damage to it.

Ease of Use

Like most power banks, the Tegic BLOCK 30 is super simple to use. Plug your device into either the USB-C or USB-A port, and it should start charging. If it doesn’t, you can press the button on the power bank to start the process, but I didn’t have to with anything I tested it on. While charging your device, the LEDs will breathe slowly, and the one on the far left will glow solid red to show charging is in process. The four white LEDs indicate how much charge is left in the memory bank, while a fifth red one (different from the charging indicator LED) glows red when less than 20% charge is left in the power bank.


While there are 60W chargers out there, the 30W output of the Tegic BLOCK 30 is plenty for most mobile devices. In addition, it supports power delivery so that you can be charging it through the USB-C port and using another device connected to the USB-A port. When tested with a USB-C voltage meter, the power bank put out the expected levels based on the device. Once charging was complete, the power bank didn’t shut off but kept trickle charging the connected device.

Battery Life


With an MSRP of US69, the Tegic BLOCK 30 power bank isn’t the cheapest on the market. However, the pricing is fair given the CNC aluminum design, solid build quality, and expected performance. Not to mention, power banks seem hard to come by if a recent Amazon search is any indication.

Better yet, Tegic has provided us with a discount code good through the end of the month. When purchased from their website, enter Tegic20 when checking out and save 20%, bringing the price down to just over US55.

The USB-C cable can be used with USB-C or USB-A connections.


If you’re looking for a power bank and want something a little different that will turn heads without sacrificing performance, you may want to look at the Tegic BLOCK 30.


Owning a power bank that uses Power Delivery (PD) is mandatory simply because most portable devices are compatible with PD. PD enables you to charge your phone or tablet fast, and in some cases, if the charging power is high enough, you can charge USB-C chargeable laptops. Having a high-capacity PD power bank is an even better choice because most devices use larger batteries.

This review looks at this ROMOSS PEA30 30,000mAh 30W Power Delivery power bank. A pretty good power bank that features nearly everything you’d want from a modern power bank, so let’s take a closer look.

Power Capacity

This ROMOSS power bank has a 30,000mAh capacity. This is a lot of capacity. Regarding charging phones, you can get about three to five total charges depending on your phone. Charging tablets or laptops will yield a single charge, and you may have spare capacity to use later. No matter how you cut it, 30,000mAh is a lot of power and is one of the best parts of this ROMOSS power bank.

I will do a capacity test video on my YouTube channel and fully review this PEA30 power bank. I’ll update this review once those are done.

Output Charging

Output charging for this PEA30 power bank is good for individual ports. However, the overall charging could use a bit of improvement.

There is a single USB-C Power Delivery port and two USB-A Quick Charge ports on this PEA30 power bank. The USB-C PD port has a 30W output; the USB-A ports have a 22.5W output. So you can use charge a laptop, phone, or tablet at their max charging speed from the USB-C port, or you can fast charge an Android phone from one of the USB-A ports.

The downside is that you can use only the fast charging from this ROMOSS power bank, only a single device at a time; this is because the max output of this power bank is 15W when charging multiple devices.

In my test, I charged a Lenovo laptop from the USB-C port, and it only charged at 3W; this is because most Lenovo laptops require that you use a 45W Power Delivery port or higher, so it’s not the fault of the power bank. However, 30W Power Delivery is still very useful for fast-charging phones and can quickly charge Macbooks.

While charging my Lenovo laptop, I plugged a Galaxy Note 9 into one of the USB-A ports, and the laptop stopped charging altogether. This shows that the power bank has a 15W max output when charging multiple devices.

When charging the Galaxy Note 9 alone, I could fast charge it from the USB-A Quick Charge port.

For the next test, I charged a Samsung Galaxy Note 9 from the USB-C port, an LG G7, and a Galaxy A51 from the two USB-A ports; all three phones were standard charging simultaneously.

The charging power from this ROMOSS PEA30 power bank is impressive when charging a single device, but charging multiple devices simultaneously could improve by making the max output higher than 15W when charging more than a single device.

Of course, it’s still beneficial when considering the 30,000mAh capacity and charging three phones or tablets simultaneously.

Input Charging

Recharging this ROMSS PEA30 power bank is phenomenal because it has three input ports. The Lightning and Micro-USB input ports have an 18W input speed for recharging the power bank. The USB-C port can be used as an input and recharge the power bank at 30W. So, the best way to recharge is using the USB-C port to recharge this power bank at 30W.

To get a 30W input speed, you will need a 30W Power Delivery wall charger or higher, but this power bank does not come with one.

Size and Weight

The ROMOSS PEA30 power bank has a length of 6.2 inches, a width of 3 inches, and a thickness of 1.2 inches. The power bank weighs 1.8 pounds. So it’s not a large power bank, but it has some weight. You’re still able to take this charger with you anywhere easily.

Functional Components

Charging automatically starts when a device is plugged into any of the ports. A screen at the top of the power bank shows the remaining capacity.

Structure and Material

The build quality of this ROMSS PEA30 power bank is excellent. Even though the charger is made of plastic, it still has a great build, with everything feeling solid and together.


There’s nothing to note about the technical build quality of this power bank, as it only gets a little warm during fast charging, but that was about it. It performs like it’s supposed to.


This is a reliable power bank for its fast charging single port, the number of input ports, and the 30,000mAh power capacity that can be used to charge devices to full power many times. Overall, the PEA30 is reliable except for its ability to fast charge multiple devices simultaneously. When charging more than a single device, the max output drops to 15W, and all the devices begin to the standard charge.

Besides that, this PEA30 power bank fits most charging needs, including being able to charge some USB-C laptops, but in our test, it could not charge a Lenovo Flex 5 laptop because the laptop is designed to accept 45W or more Power Delivery.


The 30,000mAh capacity of this ROMOSS power bank is the best part. Three fast charging ports include USB-A Quick Charge and a single 30W USB-C Power Delivery port. Three input ports include a Micro-USB and Lightning input port, and the USB-C port can also be used to recharge the power bank. The only downside to this power bank’s power is that the max output becomes 15W when charging more than a single device.

The power bank is not too large; you can still take it anywhere. It has a screen that shows the remaining capacity, and charging automatically starts when you plug a device in.

The power bank may be plastic, but that doesn’t detract from its incredible build quality.

The most reliable part of this PEA30 power bank is its 30,000mAh high capacity that can be used to charge most devices to full power many times. The unreliable part is the inability to fast charge more than a single device simultaneously.

ROMOSS PEA30 30,000mAh 30W Power Delivery Power Bank Specs


The ROMOSS PEA30 30,000mAh power bank is a pretty good one with 30W Power Delivery and USB-A Quick Charge ports; it has three input ports to recharge from and an excellent Aluminum build. However, upping that 15W max output when charging more than a single device would greatly benefit.

The Best USB C Power Banks With PD (Power Delivery)

USB C technology became quite popular in recent years, with more and more devices using it by default. So if you happen to have a phone, tablet, or laptop with USB-C ports, then you might also want to have a 100% compatible power bank as well. Otherwise, you’ll either end up using all sorts of adapters and you’ll be giving up on speed and efficiency.

This is why we made this in-depth research on the USB C power banks available on the market and shortlisted the best of them here. The main criteria we took into consideration were:

  • USB C ports for both output and input
  • The power banks must use the PD (power delivery) technology
  • They should have a fast recharging time

So without further ado, here are the best USB C power banks in our opinion:

Best overall: RAVPower 20000mAh PD 60W

  • Recharging time: 3 hours
  • Weight: 14.4 oz / 408 g

RAVPower has truly outdone itself with this 20000mAh power bank from their PD Pioneer series. They managed to create a device that’s not only powerful and fast but also has a great design. Considering the price point too, we can go on a limb and say that this is one of the best options on the market for someone looking to buy a truly dependable USB type C power bank.

review, romoss, pea30, 000mah

Capacity-wise, it’s not too small but not too large as well. It holds enough charge to replenish an iPhone 11 Pro Max 2.6 times, an iPad Pro 2018 1. 6 times, or a MacBook Pro 13″ 2018 0.84 times. This makes it perfect for daily use. You can even depend on it for several days at a time if you only need it for your smartphone.

Regarding the power output, it comes with a generous 60W maximum output via its USB C port with Power Delivery. This is enough to charge power-hungry devices such as laptops, gaming consoles, drones, etc. Besides the USB type C port, it also features a USB type A port that comes with a fast-charging technology called iSmart.

It’s also worth mentioning that the RAVPower 20000mAh PD power bank has a sturdy build. The casing is made out of thick, scratch-proof plastic with a matte surface which gives it non-slip properties. The only real downside we see to this device is the fact that it could have featured one or two extra ports.

Highest capacity: Renogy 72000mAh PD

  • Recharging time: 3-4 hours
  • Weight: 2.79 lbs / 1265 grams

This Renogy 72000mAh power bank is impressively powerful! The huge capacity will supply more than enough energy to all your connected devices simultaneously. It boasts one USB-C 60W PD port that is very proficient at charging your laptop and a USB-C 27W PD port ideal for charging your smartphone. Meanwhile, the DC 12V/5A cigarette lighter port is capable of powering CPAP machines, such as Philips Dreamstation, Resmed Airsense/Aircurve 10, and Resmed S9. However, to take advantage of this, you will need a CPAP adapter.

This power bank is suitable for your needs if you’re going camping, on a road trip, or hiking. Place it inside the storage bag, and you’re good to go! It has a built-in flashlight for your lightning needs when you’re in a dark environment. Even cooler, you can wirelessly charge your smartphone. Put it on the charging pad and track its charging status via the Smart indicator.

The Renogy 72000mAh power bank provides 14.8 charges to a 2815mAh smartphone, 5.8 charges to a 7729mAh tablet, and 5 charges to a 45W laptop. There are three different ways to recharge this power bank. One method, which takes about 3-4 hours, involves using a 100W solar panel with a two-way DC port. You can also fully charge it in 5-6 hours by using the bi-directional USB-C port. Using a wall outlet will take 7-8 hours.

Best build quality: Omni 20 20000mAh

  • Recharging time: 3 hours
  • Weight: 1.4 lbs / 635 g
  • Wireless Charging

The Omnicharge Omni 20 is one of the highest-quality power banks you can find. Everything about it from the matte outer case to the display screen and charging ports simply conveys attention to detail and an overall high build quality. But all this comes at a cost, since this power bank has a premium price, this is maybe the only real downside we can see. If you have the budget, then you simply can’t go wrong with the Omni 20.

In this product bundle, Omnicharge has included the Omni 20 power bank which has a capacity of 20000mAh, but also some very useful accessories such as a UBC-C fast charger, a USB-C to USB-C cable, a USB-A to USB-C cable, and a protective hard case. This is one of the most complete portable charger bundles you can get.

But what sets the Omni 20 aside, is the fact that it has an AC/DC plug which you can use to charge any type of laptop, as the device has a massive output of 100W! And last but not least, it also comes with a wireless charging feature which allows for phones with matching technologies to be charged only by simply placing them on top of the power bank.

  • A lot of ports, including AC/DC

USB C technology explained

For a long time, the general standard in device connectivity was the USB Type-A with its micro and mini versions. Regardless of the USB A ports version (1, 2, 3), the rectangle connectors that never fit on the first time, were ubiquitous. And to some extent, they still are.

However, things are about to change with the new USB Type C technology which shapes itself up to be the new standard in terms of connectivity. and more devices are starting to adopt this new type of port. Even Apple is on the way to replacing its famous Lightning ports with USB-C ports. And this speaks volumes about the new kid on the block, as Apple has been notoriously defensive towards their own patented technologies.

The main benefits of USB C technology are:

  • it can transmit both power and information simultaneously
  • information can be transferred at much higher speed rates of up to 10 Gbps
  • the plugs can be inserted either way, there is no right way up as in the case of USB A ports
  • these ports can be used for both input and output of power and/or information

Things tend to get a bit more complicated when you factor in the fact that USB-C is more of an umbrella term. In fact, these connectors can utilize different types of protocols such as USB 3.1 or PD (power delivery).

Power Delivery (PD)

USB-C output ports with Power Delivery (PD) can supply up to 100 watts of power. This is an important feature, as older generation USB ports could supply just 2.5 watts on average, enough for a phone but definitely not enough for a laptop that requires at least 60 watts. This is why for the list of power banks we only selected ones that have the PD feature.

However, this is not to say that all PD ports supply 100W. There can be different values of power output, but the most common ones are:

  • 18W – this is enough for all types of smartphones and tablets, including devices such as the Nintendo Switch.
  • 30W – 45W – from these levels, you can start charging more power-intensive items such as laptops, just that they will take longer to charge than usual
  • 60W – starting with 60W most laptops will charge without an issue, not to mention tablets, cameras, or phones.


It’s pretty clear that the USB-C ports are here to stay and that they are very likely to become the next standard in terms of connectivity. As more and more devices will come with this type of port, then it makes sense to make sure any power bank you buy also has USB-C compatibility.

But besides plain old compatibility, one of the biggest advantages of USB C power banks is their increased speed, where PD technology plays a key role. The maximum loading speeds of traditional ports, don’t even come close to the ones provided by USB-C with PD.

This product recommendation list is dynamic. As newer models of power banks with USB-C ports get launched, we’ll update it in order to feature the best models available on the market.
