Bought the wireless charger on a whim since, along with buying a new Samsung S8+, we got discounts if you bought 3 accessories. It's just a small convenience....saving about 2 seconds a day from plugging in a charging cable, LOL. The charge is much slower than the cable, so it only makes sense if you charge overnight, which I do.
For some reason, the new S8+ only charged to 87% before stopping....and that took about 4-5 hours. Will try it on my Note5 and see if similar results. The cable fully charges the Note5 in about 60-80 minutes or so.
Just bought a new Samsung Fast Charger off Ebay (for cheap) to see if it's any better...and to go downstairs from the Insignia one. These should be a slight convenience if you just HAVE TO plop you cell down and cannot take the 2 seconds to plug it in, but looking back, the cable is much faster and not a big deal to plug in. Just a solution where there was no problem. Progress? Hardly.
