Power outages have been occurring much less frequently in recent months than before, but that's no reason to completely forget about backup power. Especially since power banks, or universal mobile batteries, are useful not only during blackouts but also on trips, business trips, or simply when working outside the home or office.

Models capable of powering not only smartphones and other small electronics but also more demanding devices, such as laptops, are particularly relevant. One such power bank is the  Vinga 30000 mAh 100W Display VA Grey (Li-Ion) (VPBB30100) priced at ₴3600 or about $80. It combines a substantial capacity of 30000 mAh, an output power of up to 100 W, and an informative display, making it a truly universal solution for all occasions. Let's find out how successful this combination of capacity, power, and functionality is.

Specification

Packaging and Delivery Set

The power bank comes in a box with the usual Vinga device design. It features Ukrainian localization and quite informative specifications. Although the warranty period is 1 year, the device's shelf life is indicated as 3 years.

The set includes a user manual in Ukrainian and a cable with USB Type-C connectors on both ends.

The latter is made with a fabric braid and complemented by a Velcro strap. It is 96 cm long and, judging by the label, can transmit up to 100 W of power. This cable is suitable for both charging the battery and powering devices connected to it.

Appearance and Functional Capabilities

Power bank Vinga 30000 mAh 100W Display VA Grey (Li-Ion) (VPBB30100) measures 177 × 82 × 26 mm, so in terms of size, it resembles a 130-180 W laptop power adapter. Therefore, it is definitely not a pocket device, although such dimensions are quite expected for a model of this capacity. The weight is also considerable, but far from record-breaking — 566 g.

The UMB is available only in gray. The plastic has a practical matte texture in terms of marking and elongated lines on the sides, which help to securely hold the device in hand. On one of the sides, there is a single power on/off button.

On the top panel, there is a trio of output ports: two USB Type-A and one USB Type-C. The maximum power of each is indicated nearby, which is very convenient.

The highest power - 100 W - can be delivered by the USB Type-C. It is suitable for charging a laptop, console, or powering other demanding devices. Additionally, it is used to recharge the internal battery — a power adapter with up to 60 W power is suitable for this purpose. The USB Type-A ports can deliver a maximum of 18 or 22.5 W.

However, all the mentioned power values are available only when using the ports separately. If two or three connectors are used simultaneously, each of them can transmit a maximum of 15 W of power.

Additionally, the USB ports support a low current mode. It is activated by double-clicking the side button, after which the output power is limited to 7.5 W (5 V, 1.5 A). This will be useful for safely charging Bluetooth headphones, portable speakers, smartwatches, and other compact electronics that require a small charging current.

The bottom of the power bank is devoid of interesting elements.

This also applies to the back, but here there is detailed information about the input and output parameters.

Pleasantly, the manufacturer indicates not only the nominal capacity of the internal battery — 30,000 mAh (111 Wh), but also the usable capacity — 17,280 mAh (64 Wh), which accounts for energy losses during voltage conversion. This value better reflects the real capabilities of the device and allows you to estimate how many times you can charge a smartphone or how long a laptop will run. At the same time, it was obtained under a load of about 10 W (2 A at 5 V), so with higher output power, the actual usable capacity will be lower.

Returning to the front side of the device. It is adorned with the manufacturer's logo and the indication of maximum output power, but the most interesting element here is the rather large display.

It shows the battery charge percentage, operating mode — charging (IN) or discharging (OUT), as well as the current and voltage values.
Testing

Now let's move on to testing.

First, our USB tester showed values similar to those displayed on the screen, so there is no doubt about their accuracy. With its help, we measured the actual battery capacity when consuming a voltage of 5 V. The obtained value of 17,100 mAh or 57% of the nominal is very close to the 17,280 mAh indicated on the case by the manufacturer and is typical for a quality power bank with a capacity of 30,000 mAh.

As for the charging speed, it depends on the power of the used power adapter. For example, from an 18-watt charger (8.8 V and 2 A), it took about 6 hours to fully recharge the power bank.

Additionally, charging occurs without problems at a power of 60 W. Thanks to this, the duration of this process is reduced to approximately 2 hours.

Of course, we checked the ability to achieve 100 W output power and confirm — the device fully meets the declared specifications. Naturally, when operating at maximum power, the power bank heats up more, but we did not observe anything critical.

Therefore, with its help, you can power not only a mini-PC, as shown in the photo, or a laptop with an energy-efficient processor, but also a laptop with more powerful components and not too demanding discrete graphics.

Conclusions

Power bank Vinga 30000 mAh 100W Display VA Grey (Li-Ion) (VPBB30100) stands out for its combination of large capacity and high output power. Its capacity is 30,000 mAh, and up to 100 W of power is available through USB Type-C, and during testing, the device indeed confirmed the declared characteristics. Thanks to this, it will be especially useful for laptop owners, particularly models with not the most energy-efficient hardware.

Additional advantages include a good set of ports — a pair of USB Type-A and one USB Type-C — as well as an informative display. The latter allows for convenient monitoring of charge level, voltage, and current, which is especially useful when powering various devices. At the same time, USB Type-C is used not only for power output but also for charging the power bank. Thanks to an input power of up to 60 W, it can be recharged in about two hours — a very good indicator for a model of this capacity.

At the same time, when calculating autonomy, it is worth considering that the actual usable capacity is about 17,100 mAh. This is due to inevitable losses during voltage conversion and is a typical feature of power banks in general.

So, given the price of about ₴3600, Vinga 30000 mAh 100W Display VA Grey looks like a successful solution with a good price-to-performance ratio. It will suit those who need a universal backup power source not only for a smartphone or tablet but also for a laptop or other demanding equipment.
