Review on Wireless Charger: 10W Fast Charging Pad for Samsung Galaxy & iPhone, 5W Qi Stand for LG & More Qi-Enabled Phones by Tricia Smith

I used this to charge my Galaxy S9 and it took several hours because the phone was completely empty (0% charge). I've seen 15 watts but this 10 watt charger is very acceptable and I've heard of cases where 15 watt chargers can heat up the phone. Pros: Attractive rubber base to keep it in place, red light when plugged in that turns blue when the phone is charging. Cons: Does not come with AC adapter, Blue charging indicator stays off throughout charging, Color does not change after charging is complete. The last minus is actually not necessary, at least with my S9, since the mobile phone has a red LED on during the charging process, which turns green when fully charged. Conclusion: It's worth it, especially at a very reasonable price.
