Marketplace
This appears to be the new lowest price for this USB battery pack. Slightly cheaper than the last Kogan deal (which is weird given that Dick Smith is owned by Kogan now).
Pasting the description from the eBay product page below (including spelling errors in all their glory):
The Xiaomi ZMI Aura QB822 20000mAh Power Bank is a high-quality lithium polymer power bank that could charge your phone, iPad and other intelligence devices on the go.
20000mAh capacity
Stealth digital display
Dual USB output
Two-way quick charging
Can be used to charge devices with small battery capacity
Comes with overheating, overcharging and short-circuit protection
Stealth digital display shows the remaining charge
People usually pay attention to remaining charge when using a power bank. However general LEDs do not accurately identify the remaining charge, therefore the ZMI Aura QB822 power bank is designed with stealth digital display on the body. Numbers with soft light are intuitional and exquisite; moreover, you can use the indicator lights to gauge how much power you want to use so you can have charging power for a rainy day.
Dual USB output
Dual USB output is ideal for quickly charging multiple kinds of digital devices. Using a single USB port outputs 18W for a quick charge, while using dual USB ports output up to 5.1V/3.6A. The powerbank also intelligently recognises your devices for safe charging.
Dual input port
Micro USB + USB-C dual input design means the two most common interface types exist at the same time. Even if you forget to take the original charging cable, you can easily find Micro USB or USB-C cables to charge your devices on the go.
Good pickup on the price drop, it's also $29 + Delivery (Free with First) @ Kogan now also :)
