Giant Viking power bank has never been cheaper. It has 96,000 mAh and a ton of various ports

Power banks with a capacity under 20,000 mAh are great for charging a phone, but what if you need to power a laptop, a cooler box, or LED lighting for camping? The Viking VIDAR III with a capacity of 96,000 mAh currently starts on Heureka from 5,118 CZK – which is the historically lowest price since its market launch. It originally cost 7,490 CZK, so you save over 2,300 CZK.

Quick summary:
✅ Makes sense if you’re camping, working in the field, or need a backup power source for a laptop, cooler box, or 12V appliances.
⚠️ Consider if you’re planning a trek with a backpack – an extra 3 kg is not negligible.
💡 For 5,118 CZK, you get a power bank with a capacity of 307 Wh, IP65 resistance, and solar charging capability – an exceptional combination at this price point.

Why this power bank is interesting

Viking VIDAR III belongs to the category of small charging stations – it’s something between a regular power bank and a home backup battery. A capacity of 96,000 mAh (307.2 Wh) means you can charge an average smartphone approximately 16–19 times, a laptop 4–5 times, or power a 12V cooler box for several hours.

The main advantage is the wide range of outputs: 2× USB-A (18 W), USB-C with Power Delivery support (60 W), a DC-jack for laptops (84 W), two 12V/15A cigarette lighter sockets, and Qi wireless charging (10 W). The package also includes 8 adapters for various laptop types – so you don’t have to worry about compatibility with your laptop.

Key parameters explained simply

LiFePO4 batteries are safer and have a longer lifespan than conventional lithium-ion cells. The manufacturer states at least 2,000 charging cycles, which means years of operation with normal use. IP65 resistance ensures protection against dust and splashing water – but be aware, this only applies when all connectors are covered with silicone caps.

The option of solar charging up to 80 W is interesting. If you have a compatible solar panel (such as Viking L60), you can charge the power bank even out of reach of the electrical grid. The Pass-Through function then allows you to simultaneously charge the power bank and power connected devices.

Practical aspects: what’s in the box and how to use it

The power bank measures 225 × 165 × 76 mm and weighs 3.043 kg. This is not exactly pocket-sized, but the package includes a protective case with a cable pocket, which facilitates transport. Also included are an AC adapter for mains charging, connecting cables (USB-C–USB-C, USB-A–USB-C), and the aforementioned set of 8 laptop adapters.

The LED display shows the battery status in percentages, active outputs, and their current load in amperes. A practical bonus is the built-in LED light, which can serve as a flashlight when camping or as an emergency red light.

What users say

On Heureka, the Viking VIDAR III has a rating of 98% from 5 reviews. Users most often praise the versatility of outputs, durable construction, and long endurance. One reviewer writes that the power bank “lasts 14 days and handles wireless charging repeatedly.” Another appreciates the connector covers and the ability to adjust the output voltage.

Criticism primarily concerns weight. A reviewer summarizes: “Great for the car and tent, but too heavy for a trek with a backpack.” Another user points out that the power bank did not work with their CPAP device – but adds that the problem was likely with the specific CPAP device, not the power bank.

When it doesn’t make sense

If you need a power bank primarily for hiking or for your backpack, 3 kg is simply too much. For these purposes, there are more compact models – such as the Viking VIDAR I with a capacity of 38,400 mAh and a weight under 1 kg. The VIDAR III is more for car-accessible campsites, cabins, caravans, or as a backup power source for a workshop.

Also, if you have a specific device with non-standard power requirements (like the mentioned CPAP), verify compatibility beforehand. While the power bank offers a wide range of output voltages, not every device may work with it.

Verdict: who it’s worth it for

The Viking VIDAR III is an ideal choice for campers, field workers, or anyone who needs a reliable backup power source out of reach of the electrical grid. For 5,118 CZK (historically lowest price), you get a capacity of 307 Wh, IP65 resistance, solar charging capability, and a wide range of outputs including cigarette lighter sockets and a DC-jack for laptops. If you don’t mind the higher weight and don’t need to carry the power bank in a backpack for a trek, it offers a very strong price/performance ratio.

Do you use a power bank just for your phone, or do you also power larger devices?
