An Invisible Wireless Charger Buying Guide: 5 Essential Tips to Know Before Buying

We’ve all seen coaster style Qi wireless charging pads on the table before, they’ve been around for years now and very little about them has changed since their introduction. We know what to expect and how to shop for them, but is that the case when it comes to new long-distance or hidden wireless charging systems that are attached to the underside of your furniture or kitchen surfaces and send power through thick material?

A wireless charging pad for your tabletop and under your table might sound like it should be pretty similar – the one under the table just needs more power right? – Well, the simple answer is kind of. That’s because using more power to charge through a table means more excess heat is being generated and phones and their batteries definitely don’t like too much heat!

That’s why we’ve created these tips to simplify these products, cut through misinformation, and pose questions that will help you choose the safest and best product for your needs.

Wireless charging requires two key processes to work successfully to ensure your phone is being charged safely and effectively:

Power Transfer – sending a current from the charger to the phone – the actual charge
Power Communication – the sync between your charger and phone to allow the phone to send it’s charging orders and safety protocol to the charger. For example – ordering fast or slow charge, or stop charging as and when the phone asks for it. This is absolutely crucial in any charging product whether wired or wireless or short or long range – without this, a lot of things can go wrong as your phone can’t reject or stop the charger heating it up even when it’s full!
