Exceptional great phone charger with dual coil charging! I love this charger it's my favorite out of about five other ones. Thus dual coil allows the phone to charge much faster and you don't need to be as picky trying to place your phone on the charger just right to get it to charge, it can be placed vertically or horizontally on the charger. This is a very nice high quality durable constructed charger that stands up while charging for better heat release. It can also lay flat when you close the chargers kick stand, which is nice and tight with no worries of it closing on itself while charging your phone. It comes with protection measures to include: over current control, over voltage control, temperature control, short circuit prevention, effective defect metal interference and other interference. I have a rather thick case on my phone and it has no problems charging through the thick case with the dual charging coils. It comes with a USB charging cable which is convenient to charge via USB. I carry a power bank and it works very well to charge the wireless charger. I recommend this wireless charger highly over several others I have used and find the price to be exceptional for the quality.
