Announced via the company's Facebook page, the power banks feature anodised aluminium finish like the ones seen in other power banks released by the firm. It is worth mentioning that Xiaomi introduced its 16000mAh Mi Bank in November last year in China.

Notably, the company started selling the 5000mAh Xiaomi Mi Power Bank via its Mi.com portal in US, UK, France, and Germany earlier this month. The firm already has a 5200mAh Mi Power Bank available to buy at a price tag of Rs. 799.

According to the company, the portable charger can offer 3.5 full charges for Xiaomi Redmi Note 4G, which is backed by a 3100mAh battery.

The 5000mAh Mi Power Bank features one USB 2.0 port and one Micro-USB port. Measuring 125×69×9.9mm, the power bank weighs 156 grams and delivers a conversion rate same as the 16000mAh version. A per the company's claims, the portable charger can offer 5.1V/2.1A output and one full charge for Xiaomi Redmi Note 4G.

The company Facebook page also talks about a voting contest taking place on the company website. Users would have to vote for one of the two power banks, which they want to see going on sale first on June 9 - voting ends on Tuesday.

Earlier this month, Xiaomi launched the Mi 10000mAh Power Bank in China, a slimmer version of the firm's 10400mAh portable charger that was launched last year. The batteries housed inside the Xiaomi 10000mAh power bank are manufactured by LG and Panasonic, says the firm.

How to Download and Install Android M on Your Google Nexus Device

Android M, the latest version of the world's most popular mobile operating system, was announced at Google I/O 2015 on Thursday. Android M is still some time away from being ready for rollout - the launch to consumers is expected in Q3 of this year - the preview version for developers is now available.

This version of the OS is not ready for most people and we strongly suggest that you do not try installing this on your primary device as there is a good chance that there are bugs to iron out at this stage. If you have a spare Nexus device that you want to try the Android M preview on, then you can go ahead and follow the steps described later in this article. Before you do that, it's vital to take a full backup of your Android smartphone.

Android M preview is currently available on just four devices - Google Nexus 5, Google Nexus 6, Google Nexus 9, and Google Nexus Player.

Here's how to manually download Android M preview and install it on your Google Nexus devices.

1. Download and install the latest Android Studio Preview on your Windows computer. This installs the ADB and Fastboot programmes, which can be accessed through the command terminal on your PC.
2. Add the SDK folder to the PATH by following these steps:
3. Right click My Computer and click on Properties.
4. Click on Advanced System Settings.
5. Click on System Properties > Advanced > Environment Variables.
6. In the Window, select Path, then click on Edit, and then type in the name of the directory where you installed the SDK, and remember that each entry is separated by a semi-colon.
7. Enable USB debugging on your device. First, go to Settings > About Phone > Software information.
8. Tap Build number seven times.
9. Go to Settings > Developer options. Tick USB debugging.

Download the correct factory image for your device.

10. Extract the image on your computer.
11. Connect your device to your computer over USB.
12. Start the device in fast boot mode.

The easiest way to do this is to hold a key combination while powering up the device. For Nexus 5, hold the volume up, volume down and power buttons while powering on the device. The full list of key combinations for different devices is here.

You can also boot into fast boot mode using the ADB tool: With the device powered on, go to the command terminal and execute the following: adb reboot bootloader

If needed, unlock the device's boot loader through your computer using the command terminal and executing: fast boot oem unlock

Open a command terminal and navigate to the unzipped system image directory.

Execute flash-all.bat, which was a part of the unzipped image file. This script installs the necessary boot loader, baseband firmware(s), and operating system. For this to work, you need to have added the folder where ADB and Fast boot are installed to the system's path as described in step 2.

When this is done, Google recommends that you lock the boot loader for security. You can do that by booting the device in fast boot mode while still connected via USB, and using the command terminal to execute: fast boot oem lock.

That will install Android M preview on your Nexus device. Android M will receive monthly OTA updates until the final version ships, according to a report, so you won't have to repeat this complicated process again. We still recommend that you just wait a while until the OTA update arrives on your device, unless you want to stay on the bleeding edge of smartphone OS development.
