April 2 2018: For some days now, I have been trying out Belkin's Wireless Charging Pad ( Model F8M747), a thin disk-shaped device less than 100 grams in weight, with a non slip bottom and a USB to micro USB connector ( for charging.
Once charged (or even when connected to the mains) it is ready to charge phones and tablets wirelessly -- just place the Qi-ready phone on the pad. An LED light starts flashing as soon as a phone is placed correctly and is charging.
I wish Belkin had provided the mains charger for the pad and not just the USB cable -- this is because it needs a 2A charging current and I had to search among my phone chargers for one.
Otherwise this is an elegant device that provides a 5W charge -- enough for all phone makes. For Vivo and Oppo phones I had to buy and add a Qi patch.
The Belkin wireless charger costs Rs 2999, though some e-commerce sites have it cheaper. ANAND PARTHASARATHY.
