I have purchased Jiofi( m2s) 4g portable wifi router at rs 800, 1 months ago . It comes with glossy finish .
It has one nano sim slot and a memory card slot. It has battery of 2300 mah .It takes around 1.30 hours for full charge with its 5v 1 ma charger which come along with the box . This device gives a battery backup around 8 to 12 hours. It also have a stand by mode of 30, 60 min. If wifi is not connected in set time then the device will automatically shut down.
User can connect upto 31 devices to it . I have a Laptop and 3 smartphones of me and my family members connected to hotspot.
It is giving Maximum internet speed of 17 Mbps download and 9 Mbps while Minimum speed of 1 Mbps download & 400 Kbps upload .
I have shared screenshot of Internet speed test at different time of the day .
You can share Internet either via hotspot or through USB ethernet connection, also you can adjust the range of your hotspot which can increase battery backup .
Data of memory card can be shared or accessed through hotspot.
It has a disadvantage that is you can only insert jio sim in it, also its charger stop working after 6 months .
Overall performance is good .
