Battery anxiety sounds a bit like WiFi anxiety – a fear of deprivation.
Whenever we’re loafing around in pubs, planes, restaurants, cafes, hotel rooms, waiting rooms, offices, coffee shops, betting shops or in cars, buses or trains we are liable to go down with battery anxiety.
Your friendly publican, plane-maker, restaurateur et al will come to the rescue with a charging plate, hopes IDT.
IDT has sold wireless charging technology to IKEA for them to add it to a table light.
No more fiddling around with plugs and sockets – just toss whatever it is you want charged on a plate.
As owner of a Philips Sonicare toothbrush which you drop into a tooth mug to charge, I am half convinced about the convenience of wireless charging.
IDT, having snaffled Samsung and LG is now going after smaller, but more plentiful fish with a Qi-compliant transmitter kit with a BOM of $40 and a receiver kit with a BOM of $30.
“Any fool can make wireless power work, but making it work at a reasonable cost with reasonable performance takes considerable engineering skills,” IDT’s Graham Robertson tells me.
As someone who carries a spare phone battery around, I have never suffered from phone battery anxiety but, as someone who daily charges a wet toothbrush in a wet bathroom, I can see the advantages of wireless charging in wet places like boats, kitchens, gardens, parks and Scotland.
Robertson reckons consumers will also appreciate a charging ‘tray’ on which you can drop anything that needs charging without having to plug it in.
$30 is not much to add to a phone but it’s quite a lot to add to a toothbrush or a toy.
IDT’s transmitter and receiver reference kits include reference boards and design support materials including instructional videos, user manuals, foreign object detection (FOD) tuning guides, layout guides, layout instantiation modules, schematics, bill-of-materials (BOM), Gerber files, and more.
