With railways running peak timetables, and galas / events being held nearly every weekend, it is always useful to have a backup battery for your phone, camera batteries or even a laptop.

This new power bank, sent to RailAdvent for a review, from PowerAdd brings 100w power and a multitude of ports and a 20000mah battery to a package small enough to fit into even the tiniest of camera bags.

Power banks come in all shapes and different sizes, right down to lipstick sizes for a quick top up. However, this one packs in enough power to charge MacBook Pros, Surface Pros or even high end gaming laptops.

The power bank has a simple design to it, with a metal casing with simple branding on the side and the ports on the top.

We have found the ports on this to be just right for everyday use. 2x Type C ports that support input for charging the unit and outputting to devices whilst there is a USB A that can help charge older devices or lower powered devices like headphones etc.

The Type C1 port has a max input/output of 100w. The C2 port has a max input of 60w and a max output of 65w whilst the Type A supports the QuickCharge 3.0 protocol, providing 22.5W of power.

You can use all three ports at the same, though obviously, power will be split across all three.

This makes it great for not just gala trips but also flights and camping. The battery capacity is below the flight regulations, making it safe to carry onto a plane.

Some power banks state they charged / output at up to 100w but in reality do not get up to such high speeds, however, we have tested the ports on this power bank and they do indeed charge the unit at 100W, which will mean, provided you have the right power adapter, be able to charge the powerbank from 0% to 100% in just an one hour.

Measuring in at 10.5cm x 5cm x 5cm, the power bank is compact and is also lightweight, weighing in at just over 400 grams, which is something you need on a gala or camping trip.

The LED lights on the top tell you how much power the unit has left, though if we are being picky, we would have liked to have seen a small screen on the front which tells you as a percentage how much power you have left and also it could tell you straight away if it is definitely outputting at the correct wattage.

In the box, you get a manual and a USB C charging cable to get you up and running, a small pouch would have been nice but at this price point you cannot complain.

Oh yes, we havent mentioned how much the price of this powerhouse is… it is currently available for just £37 here in the UK on Amazon.

Compared to the price of an equivalent Anker 737, which is available for around £90 here in the UK – it is a great price.

Whilst we do have to bear in mind that the Anker has a slightly larger capacity (24000 mah compared to PowerAdd’s 20000 mah) and slightly higher output capacity (140w compared to PowerAdd’s 100w), this is an extremely competitively priced unit for such a big amount of power.

In summary then, we love this power bank, it provides such a high amount of power in such a small package and it is definitely in our ‘must have’ gala bag and checklist, and we recommend adding it to yours too!
