It's not rare for a power bank to come with a charging cable, but I appreciate that this one has been built with care to suit both micro USB and USB-C users with the same cable, as seen in the above gallery.
This should be able to recharge most phones at least two and a half times from a single charge, plus this power bank can be charged up by either microUSB or USB-C so you won't need to have a specific cable with you to pump it up again when it's out of juice.
It may be quite heavy, but this is only 1.3cm thick, making it a great device to slip into your back pocket when you're out and about. You'll want to grab a cable to go with it though as unlike the Iceworks choice above it doesn't come with one built in.
I love this little guy. The Anker PowerCore II 10,000 power bank is perhaps the most portable option on this list and allows you to have at least two full charges for your phone in your back pocket ready to go.
This Omars power bank can be charged up by its USB-C port, letting you fill it up quickly, and also comes with a USB to USB-C cable, so you can power up your modern Android phone, tablet or iPad Pro without having to remember your own.
Nikon has also furnished it with the same 180k-pixel RGB metering sensor and the tilting screen on the back is just as large at 3.2 inches in size, although not quite as detailed, and it's all wrapped up inside a weather-sealed body.
Canon's best budget EOS DSLR, the Rebel SL3 – also known as the EOS 250D – mixes a strong feature set with great handling, despite its small size. The Nikon D3500 is even smaller still, but lacks this camera's flip-out LCD screen, which is handy if you want to shoot video.
