The Belkin 20,000mAh Portable Power Bank is available at Argos for £27.99, offering enough capacity to charge a smartphone multiple times over and support up to three devices at once.
The power bank provides backup power for smartphones, tablets, wireless earbuds and eReaders. Its 20,000mAh battery capacity can deliver multiple full charges for most smartphones, with the exact number depending on the device's battery size and charging efficiency.
Charging multiple devices at once
The device features three ports, including two USB-A connections and one USB-C port, allowing users to charge up to three devices simultaneously. This is particularly useful when travelling with family or friends who need extra battery life.
It supports charging at up to 15W and includes pass-through charging, which allows the power bank to recharge while simultaneously powering a connected device. This enables users to make the most of a single plug socket when staying in a hotel or travelling. LED indicators show how much battery life remains, and the power bank takes approximately five hours to recharge fully.
Portable design and customer feedback
Despite its capacity, the charger is designed to fit into a bag for everyday use, making it practical for a work bag, backpack or suitcase. It comes with a 15cm USB-A to USB-C cable and a two-year manufacturer's guarantee.
The Belkin 20,000mAh Portable Power Bank has more than 1,600 reviews at Argos. One customer said: "I bought this to use in my caravan and it was perfect. It kept my mobile charged for five days. Easy to use. Very good value."
Another added: "Better quality than a lot of power banks on the market. This one has a genuine 20,000mAh capacity. It's a bit heavy but I suppose that's a good thing as it's packed with batteries!"
A third person commented: "Excellent, compact and fits in my bum bag. Great for travelling." Some disagreed slightly, with one saying: "A little large physically compared to others, but it does the job." Another added: "Seems to work well and looks good, however it is heavier than I would have liked."
