(Last Updated On: June 17, 2023)

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.

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.
