ZDNET's key takeaways

The Baseus 30W, 10,000mAh magnetic power bank with a built-in USB-C cable is currently marked down to $27 on Amazon with a 40% off coupon. It's a great all-in-one power bank that works for a wide range of devices.
However, it's a bit chunky and heavy compared to other 10,000mAh power banks.

One of my wish list devices has been an all-in-one power bank that does wireless charging, has a built-in USB-C cable, and has a USB-C port. I've tried quite a few, and all were a disappointment in one way or another.

Until now.

The Baseus 30W, 10,000mAh magnetic power bank with built-in USB-C cable is about as close to perfection as I think things can get.

So, in a nutshell, what we have is a decent-sized power bank that has built-in wireless charging that works with iPhone and Android devices, there's a built-in USB-C cable for, well, all things USB-C, and there is a separate USB-C in/out port for charging and powering other devices.

The nice thing about this power bank is that it supports pass-through, which means that you can simultaneously charge the power back and also be charging other devices.

It's a nice feature because it means you can travel with a single charger and split that power out to multiple devices through the power bank.

There's a lot of thought put into the construction of this power bank. 

For example, normally I don't like built-in cables because they seem weak and look to be easily damaged. Baseus has used a stout cable that looks to be up to the job and even included a dummy USB-C port for you to tuck the connector into to make a carry loop.

It's a great package. Sure, it's a bit bigger than some other 10,000mAh power banks, but it's not so big that it won't fit into a pocket. And Baseus has packed a lot into this package. There's also the added advantage that you don't need to carry a charging cable, which saves a bit of room.

I've done my usual tests on this power bank, from safety checks, capacity and power output tests, and thermal checks -- and this passes with flying colors.

ZDNET's buying advice

The Baseus 30W, 10,000mAh magnetic power bank with built-in USB-C cable quickly became my favorite power bank, and the fact that it's 40% off makes it that much more of a solid deal.

It's the unicorn device that I've been in search of for some time now -- a power bank for my smartphone and other small devices that does it all and doesn't need a cable. Sure, it's not going to be powering my MacBook Pro, but for keeping my iPhone going or charging a few devices on a nightstand at a hotel when traveling or in a tent, this is as close to perfect as things get.

This has earned a place in my kit.
