Bought this powerbank from Dick Smith for $25. It takes a while to power up to 100% but the charge lasts a long time. I used it every day on a trip overseas and it would last sometimes up to 2days beforr needing to be plugged into the wall again. Only downside is that it's quite a heavy unit and not particularly small so when you add your phone's weight, it can be a bit of a pain to lug around. Takes up more room in my handbag than I would've liked.

Not only does it carry heaps power to share, but it charges your phone very quickly.

Only downside is that when the powerbank is very low on charge, you have to charge it almost overnight to get it back to capacity.

This power bank is incredibly reliable and hasn't let me down. It works well, holds its charge and charges fairly quickly. The included microusb cable is also very good. Highly recommend buying this.

Had 2 of these for over 18 months and they're still going strong, charges quicker than my Romoss Sense 4 10400mah, not sure why but it does, however I have noticed the Romoss last's a bit longer, I'd honestly rather the quicker charge....

Only gripe is the supplied cable isn't the best but any generic USB cable works fine, 2 ports would be nice too.

I brought mi 10000mah power bank in november 2016. In this duration, i have been to service centre twice. 1st time, USB cable stopped responding and then 2nd time went for battery issue of powerbank. Powerbank was taking too much time to get charged and when the time came to charge my phone, it showed only single cell in power bank. I asked the service center representative to change it then they replied that it has only 6 month warranty. Which means that MI products do have a reliability issue and the live of powerbank is not even more than 6-7 months. I have given 1 start and recommend the prospect to not to purchase MI products.

This is a great product. It charges phones fast. The build quality is excellent. It can easily be considered as an Apple accessory if you ignore the Mi logo.

There are plenty of fakes out there. Buy from a reputable seller. The box has a scratch code that can be verified on the xiaomi website.

The aluminium body scratches phones if not used carefully. I purchased a rubber cover for it to solve the issue.

I've had this power bank for several years and can find no fault.
I always have it with me when I go out for the night, camping or look like i'll have limited access to a power point.
I'll recharge my Samsung galaxy S4 at least twice and will hold a full charge for months.

It comes with a micro usb cable which can be used to recharge the power bank from a USB power source or charge your device from the power bank.

I recommend getting a solar panel for recharging the power bank while camping off grid.

Best of all the price is quite good for the excellent quality.
