You have a wide selection if you’re searching for a power bank for your devices. Power banks can have all sorts of different features; however, the two main ones that you should keep a lookout for are if a power bank has a high capacity and fast charging; that’s because, at this point, most portable devices have large batteries and are compatible with some fast charging technology. 

In this review, I’m looking at the ROMOSS Sense8ps Pro 30,000mAh power bank. This is an excellent choice if you want a high capacity with fast charging, but it has limits.

Power

Power Capacity:

The power capacity for this Romoss Sense8ps Pro power bank is 30,000mAh, and that’s a lot of power. Of course, the starting capacity isn’t a realistic amount you can fully use, and I will be doing a capacity test on my Youtube channel pretty soon and have a link to that here.

In the meantime, a 30,000mAh starting capacity is still a lot of power to use, and you can average about two to four full charges for some phones, but it all depends on your phone. If you’ve got a base iPhone 14, which has a 3,279mAh battery, you can expect to get about four full charges if you’re solely using this ROMOSS power bank to charge your iPhone 14. However, on the other side of the spectrum, a Samsung Galaxy S22 Ultra that has a 5,000mAh battery will likely fair about two or three full charges because it has a massive battery.

Charging tablets and laptops with this power bank will likely yield at least one full charge, and you may have excess capacity. Overall, this ROMOSS power bank’s capacity is plentiful and a strong point.

Output Charging:

Charging from this ROMOSS Sense8+ power bank is interesting, with a USB-C Power Delivery port and two USB-A Quick Charge ports. Taking a look at the ports at face value, they look great because the USB-C port capable of outputting 30W of Power Delivery, but only if you’re charging a single device at a time. The two USB-A ports can output 18W, but only if you’re charging a single device.

If you’re charging two or more devices simultaneously from this ROMOSS power bank, the max output of this power bank becomes 15W; as a result, you will only be able to standard charge devices when charging more than one at a time. To fast charge your phone or a USB-C laptop from the USB-C PD port, you have to do it alone with no other devices charging.

Individually, the charging ports are great but fall a little short when used simultaneously because of the max 15W output limit.

For testing, I plugged in a Lenovo IdeaPad Flex 5 laptop to USB-C PD port alone, and it was only able to charge at about 5W because most Lenovo laptops require a 45W PD port higher. That said, the 30W of Power Delivery from the UBS-C port is still enough for other USB-C laptops, especially the Macbook that will charge from the USB-C port. When I plugged in a Galaxy Note 9 to a USB-A port, the Lenovo laptop stopped charging altogether to show that the max output of this power bank becomes 15W when charging multiple devices.

I unplugged the Lenovo laptop, and the Galaxy Note 9 could fast charge. I then plugged in an LG G7 and Galaxy A51 to the two USB-A ports, and the Note 9 was charging from the USB-C port, and all phones were only able to standard charge.

The power output for this ROMOSS power bank could use an increase as that would allow for fast charging of multiple devices simultaneously. As it stands, you cannot fast charge various devices.

Input Charging:

The recharging is more impressive than the output because you can use one of three input ports. A Lightning, Micro-USB, and USB-C port can be used as an input port to recharge the power bank. The Micro-USB and Lightning input ports can recharge this power bank at 18W if you have a powerful enough wall charger.

However, we recommend using the USB-C port to recharge this power bank and a 30W Power Delivery wall charger, as you can recharge it at 30W. Still, having the option to use the other two input ports increases reliability and lets you use nearly any cable to recharge this power bank.

Design

Size and Weight:

This ROMOSS power bank has a decent size of 6.6 inches, a width of 3.1 inches, and a thickness of 1.3 inches—the weight of the power bank s 1.5 pounds. So not exactly a mini power bank, but you can easily hold it or place it in a purse or backpack and take it anywhere. The 1.3-inch thickness may make it difficult to put it into your pocket.

Functional Components:

Charging automatically starts when you plug in a device to the ports. A power button off to the side lets you turn on the screen at the top, showing the remaining capacity and a blue lightning symbol to indicate fast charging.

All of the ports can be found on a single side.

Build

Structure and Material:

This power bank is made of plastic and feels like a standard build. The charger feels solid overall, but you should be careful not to drop it or expose it to water. We couldn’t find anything badly built about it. It’s simply your standard issue power bank build quality.

Tech:

This power bank only got warm when I was recharging it at 30W. Other than that, this power bank has kept cool and showed no technical build quality problems.

Reliability

The unreliable part of this ROMOSS Sense8ps Pro power bank is the 15W max output when you’re charging multiple devices simultaneously because that 15W limit only lets you standard charge devices simultaneously.

When you’re from a single port at a time, you can use the 18W from each USB-A port and the 30W of Power Delivery from the USB-C port. The recharging is also a heavily reliable part because there are three input ports, two of which have an 18W input speed, while the USB-C port can be used to recharge the power bank at 30W.

Included in the box is a USB-C to USB-A cable.

Summary:

Power:

The 30,000mAh capacity will help charge phones to full power multiple times and get particular laptops and tablets to full power simultaneously. Charging power is alright, but this ROMOSS power bank could use an upgrade to its max output with multiple devices charging simultaneously. For single-port charging, though, the USB-C port has a 30W PD output, and each USB-A port features Quick Charge.

There are also three input ports to use.

Design:

This is a relatively small power bank with a 30,000mAh capacity. You can easily hold or place it into a bag for portability, but putting it into a pocket may seem tricky. The display shows the remaining capacity and fast charging status.

Build:

The power bank has an alright build, but it’s just made of plastic, and you should be careful not to drop it.

Reliability:

This power bank is reliable enough for charging phones and USB-C chargeable laptops. In my test, I could not charge my Lenovo laptop at an acceptable speed, even when charging from the USB-C port alone.

Conclusion:

This ROMOSS 30,000mAh Sense8ps Pro power bank is a capable charger with nearly every part, from its capacity to its charging ports and design. The biggest flaw is the max output being lowered to 15W when you have devices charging simultaneously; other than that, for the price, the features you’re getting with this ROMOSS power bank are very much worth it.
