It's simple. If you want faster charging you need more watts! And, if your phone is Qi-enabled, you can charge it wirelessly without using any cables which is actually pretty neat.
Wireless charging pads look great on your desk and so does the Boost Up wireless charging pad by Belkin, which is perfect for a bedside table.
The Boost Up wireless charging pad is a sleep friendly wireless charger as it doesn't have no cooling fan built-in and it won't light up your bedroom like a christmas tree.
In fact, the Belkin Boost Up wireless charging pad has virtually no lighting aside from a very tiny led that flashes green during the charging process. The led is actually a useful feature because it only lights up when the phone is correctly positioned on the pad.
As far as charging from 0% to 100%, the Belkin 15W wireless pad charges a Galaxy Note 8 at around 1.5% per minute so 100% charge takes 90 minutes. The Galaxy S9 series is said to have an upgraded wireless receiver so charging should be even faster.
From a 600mA input, the Boost Up wireless charger adapter outputs 2A at 12V which translates to a steady 15W of output power, which is almost twice as much as the 9W Samsung Fast Charge wireless pad.
The Belkin Boost Up wireless charging pad performs even better than expected because it can charge the phone through a leather/plastic wallet case as long as the case is no thicker than 3mm.
The low profile of the Boost Up wireless charging pad is another benefit as it's only one centimeter high. The smooth non-slip matte surface on the top and bottom is also great as it prevents the phone and unit from slipping.
As mention earlier, the Boost Up wireless charging pad can deliver 15W fast charge as long as your Qi-enabled phone supports Qi wireless fast charging. This includes the Samsung Galaxy Qi models Note 8, S8, S8 Plus, S7 and S7 Edge.
Not everyone can certify a product. Only companies that are members of the WPC can Qi-certify a product. Best way to tell whether a product is Qi-certified is to search the database of the Wireless Power Consortium.
