Review on JDB USB Wall Charger 5V/2.4A Dual Port Foldable Charger Plug 12W Portable Universal USB Charging Block 4 Pack - Compatible with iPhone, iPad, Samsung, and More - Enhanced SEO by Tony Bennett

I got tired of buying these because of all the 'solid' complaints in other reviews. I tested all 4 of my chargers and also I heard a noise when starting. And that's in my ear, otherwise there's no sound from them. If this develops over time I will come back and update the review. From day one today I am very pleased with how quiet all four chargers are. Sure, they're not "fast chargers," but as a compact travel charger, they're great for charging your device at night while you sleep. I will bring a QC 3.0 compatible single port travel charger for quick charging when needed and one of these for backup or additional devices. My 2 $20 Anker chargers are being returned to keep.
