Nomad Unveils New 'Base Station Stand' Wireless Charger for iPhone and AirPods

Battery life.

Except the link you provided has nothing to do with mid-day few minutes charges all the time. It talks about overnight charging, completely different story.

It makes charging easier. ('https://www.apple.com/batteries/why-lithium-ion/')
Charge your Apple lithium-ion battery whenever you want. There’s no need to let it discharge 100% before recharging. Apple lithium-ion batteries work in charge cycles. You complete one charge cycle when you’ve used (discharged) an amount that equals 100% of your battery’s capacity — but not necessarily all from one charge. For instance, you might use 75% of your battery’s capacity one day, then recharge it fully overnight. If you use 25% the next day, you will have discharged a total of 100%, and the two days will add up to one charge cycle. It could take several days to complete a cycle. The capacity of any type of battery will diminish after a certain amount of recharging. With lithium-ion batteries, the capacity diminishes slightly with each complete charge cycle. Apple lithium-ion batteries are designed to hold at least 80% of their original capacity for a high number of charge cycles, which varies depending on the product.

Looks very good but the price is expensive. I have been recently looking for wireless charger, is there any that has similar clean design like this but cheaper ?
