Don't make the same mistake I did when I bought a new USB power bank charger

We've all been in that situation where your smartphone is low on charge, and there's no power socket nearby, which is where a power bank can come in.

These usually have a high amount of power that could charge your iPhone or Pixel device, around five times over. They've saved me countless times, and after owning one from Anker, I decided to upgrade to one with higher capacity and more ports.

How did I get here?

I bought a Kilponen Solar Power Bank 26800mAh, mainly due to it being lighter in weight, alongside a slightly higher capacity than the 20000mAh I owned before from Anker.

Having a solar option to help recharge was a nice touch I thought, especially for adventures planned across the year, and was happy once it arrived.

Lighter, more capacity - you'd think that I'd be happy with this, and that would be the end.

But the day after charging it up and putting it in my bag, my iPhone 13 Pro needed a recharge as I forgot to plug it in the afternoon before. And, like the hundreds of times before, went to grab my USB-C to Lightning cable, plugged it into the power bank and the iPhone, and waited for the prompt to appear.

But no vibrate or alert occurred on the iPhone. So I plugged in my USB-C to USB-C cable to see if the MacBook Pro 14-inch would charge from it, but instead the laptop was charging the Power Bank.

It wasn't until I looked at the small print on its product page, which states that only two ports, the two USB 3.0 ports, can charge your devices.

You're probably thinking - why don't you know this about power banks?

Well, my previous one from Anker featured a USB-C port that could charge my devices, so I thought it was a standard across all power banks.

There's a bunch of devices that I always have to keep in mind when I look at a power bank, as my bag has the space to store them all:

While most of these can charge through a USB port, USB-C wires are becoming more common, which is why most of the cables in my bag are only USB-C.

Looking into power banks with USB-C ports, it wasn't until I spotted that the ones that could charge devices through this port, had PD (Power Delivery) alongside the product name.

These are the ones to look out for - as long as the product pages state that all ports can charge, you're good to go.

However, let's be clear - buying power banks should be a straightforward affair. If you see one that has countless ports, with a big capacity and a low price, you're likely going to buy it just from the description.

That's what I did, but I recommend that you don't do this. Read the reviews for these power banks, go through the specs, and don't do the rookie mistake that I did for something as simple as this.
