ROMOSS Power Bank SENSE8+ Review

The SENSE8+ is a powerful, 30000mAh power bank that’s produced by ROMOSS, a direct-to-consumer manufacturer whose products aren’t available in retail stores. They sell solely through online outlets. This ROMOSS power bank is the largest devices in a series of different capacities ranging from 10000mAh to 30000mAh.

Charging Technology

The ROMOSS SENSE8+ comes with five different ports. For input, it accepts Micro-USB, lightning, and USB Type-C. For output, it features two USB 3.0 ports, as well as the same Type-C port that’s used for input. The Type-C port and one of the USB 3.0 ports support quick charging, which allows for rapid charging, both of your devices and of the power bank itself.

ROMOSS 30000mAh power bank

If you recharge via USB Type-C, the SENSE8+ will fully charge in about 11 hours, which isn’t bad at all for a power bank of this capacity. If you charge it via Micro USB or lightning, it will take about 21 hours to charge. As a result, you’ll be far better off using the Type-C connection when possible.

The SENSE8+ can charge up to 3 devices simultaneously. All 3 charging ports will operate at full speed, even with multiple devices connected. It carries enough charge to recharge an iPhone X 7.5 times, or a Samsung Galaxy S10 about 7 times. You can even fully recharge a Nintendo Switch 4 times. With the quick-charge port, you’ll even be able to recharge a Nintendo Switch while playing. You can even charge a laptop, such as a MacBook Pro, to which the SENSE8+ will fully charge up to 5 times.

ROMOSS power bank ports

This power bank also supports pass-through charging. In other words, you can charge a device at the same time as you’re charging the SENSE8+. Keep in mind, though, that if one of your devices takes USB Type-C, you’ll have to charge the power bank via Micro USB or lightning. In other words, the power bank will drain during this process, albeit slower than it would if you didn’t have it plugged in.


This ROMOSS power bank measures 6.6 inches in length, 3.1 in width, and 1.3 inches in thickness. As a result, it’s fairly beefy, about the size of two large smartphones in cases, stacked on top of each other. It weighs 1.48 pounds, which is a bit hefty for the size. Even if you can fit it in your pocket, you’ll feel the weight. That said, it’s not too big to carry in a laptop bag or backpack. In these scenarios, you can carry it very easily.

That said, you won’t be able to take the SENSE8+ on an airplane. It has a capacity of 111-watt hours, which is 11 more than TSA regulations allow for. Sure, it’s probably not going to get flagged by security. But it’s not worth the risk of having your power bank confiscated.

Look and Feel

The SENSE8+ is constructed from ABS plastic, with white panels on the front, back, and one of the long sides. The short sides are grey, as is the remaining long side. It has an internal aluminum frame, which assures that it won’t get easily damaged like some power banks. It has a satin finish, which means it’s relatively scuff proof, but it won’t shine too much. On the front, there’s a grey ROMOSS logo, along with the inscription “30+”. There’s also a row of 4 yellow LED lights, which indicate the overall charge level.

On one side, there’s a small teal power button that allows you to turn the power bank on and off. The power ports are all located on the short edge of the unit, so you can easily connect multiple devices without your wires getting tangled. You can even leave it in the side pocket of your laptop bag while you’re charging your devices. One thing to be aware of is that the markings on the charge ports aren’t very clear. Meanwhile, the instruction manual is only written in Chinese. That said, we’ve already told you what you need to know, and other than the port markings there’s not really much to understand.

Durability and Build Quality

The SENSE8+ is fairly well-constructed for an ABS plastic power bank. It doesn’t carry any type of shock or drop-resistance ratings. However, it seems fairly sturdy, and we haven’t seen any reports of one getting damaged by a drop. More concerning is the fact that it’s not water-resistant, and carries no IP rating of any kind. As a result, it’s not well-suited for camping or backpacking, where it will invariably get wet. That said, it does come with a 12-month manufacturer’s warranty, so you should be covered for any serious failures.

ROMOSS has not provided any cycle ratings, which means we can’t be certain of how many times you can charge and discharge the SENSE8+ before it starts to lose power. Once again, though, we haven’t seen any reports or complaints about it failing prematurely. And if you do use it very heavily, you’re covered by the 12-month warranty. It runs cool, without any overheating issues. It also carries a full array of protection. These protective ratings include overcharge protection, overcurrent protection, voltage surge protection, power surge protection, and short-circuit protection. It also features temperature protection, so if it does happen to get hot, it will automatically turn off.

Final Thoughts

The ROMOSS SENSE8+ is an exceptionally powerful power bank, especially for the size. It’s a great choice if you need to charge multiple devices at the same time, especially devices with large batteries. The quick charge technology is especially powerful. You can use the USB 2.0 port to charge your laptop, while continuously keeping the SENSE8+ topped off via USB Type-C. That said, it’s not for everybody. The lack of water-resistance makes it a poor choice for campers, and the 111 watt-hour rating makes it a nonstarter for frequent flyers.
