Powerbanks are pretty common these days but the ones that are capable of charging your MacBook are quite rare. So, when we chance upon this Macbook powerbank from Xiaomi, we bought it and tested it out. ZMI (pronounced as zi-mi) is a sub-brand under Xiaomi. This is actually the first time we saw this become available locally.
This is a large-capacity powerbank, rated at 20,000mAh. The body is made up of ABS with a matte finish (dark blue color) that feels like anodized aluminum and is quite hefty (402 grams) to carry around. There are 2 USB Type-A ports and a USB Type-C port on one end. There’s a charging indicator on one side and LED lights to indicate charge level.
It comes with two charging cables in the box — one Type-A to Type-C (with micro-USB adaptor) and another Type-C to Type-C cable.
All USB ports support Quick Charge 3.0 with the Type-C able to output 45W of power to drive your Macbook. You can charge a maximum of 3 devices at the same time with this.
The powerbank also doubles as a USB hub which can be very useful for MacBooks that only have Type-C ports. You can plug in a flash drive or even an external HDD into the powerbank while it’s connected to the Macbook and you can access all your files right thru the powerbank. You can even plug a wired mouse thru the hub.
What’s also nice about this is that it has bi-directional Quick Charge which means you get to re-charge the powerbank really quick as well (3-4 hours). You can even use your MacBook’s wall charger to recharge it.
The powerbank is a little bulky although the size is the same as your typical 6-inch smartphone (almost identical to the OnePlus 5T in width and length). It has a carrying case as well but this is really meant for stowing in your backpack and when traveling.
This is a really good powerbank for heavy users since it can re-charge almost any devices you’d like to carry around (smartphones, Nintendo Switch, Macbook, Sony cameras and more).
The ZMI 10 powerbank sells for Php2,399 over at Smart Futures in Circuit Makati. It’s pretty cheap actually considering I bought a similar MacBook powerbank last year for around Php5k in the US.
