Review on 🔌 Costyle Dual USB Wall Charger for Fast Charging - 3 Pack, Quick Charger 3.0 & 5V 2.4A Ports, iPhone 11 XS Max, Samsung Galaxy S10 S9 S8, Note 8 9 10, Pixel Compatible (Black) by Anthony Hicks

They are useless and do not charge at the advertised price. Was used on a Nintendo Switch and died while playing despite showing it was charging. This also happens with my iPad and my iPhone. It says the device is charging, so it must be doing something, but it must be an extremely slow charging rate because devices are actually being drained while charging. I've tried this with multiple devices and multiple cables of different sizes and it happens every time. The common denominator here is the loading unit. I've replaced the units (which are actually slower and older) and used the same cords and devices and they charge well during use with no issues. Wouldn't recommend, wish I hadn't noticed sooner so I might go back, but I've never tried turning on my switch while charging, just left it plugged in overnight so never noticed how slow the charging speed was .
