USB charger for iphone, mobile phones and other 5V USB devices.How Does Qualcomm Quick Charge 3.0 Work?To help speed up the charge rate the voltage and amperage need to be adjusted. Since they’re both interconnected, and because there’s the component of resistance in there too, the ratios must be monitored and adjusted as the battery is “filled” with its charge.Think of this as filling a pitcher of water. You can fill it with a trickle of water and you won’t risk spilling a single drop – but it will take a long time. You can fill it with a firehose, but after a split-second burst there will be water everywhere, and after the hose is shut off, you’ll likely see that hardly any water stayed in the pitcher. Instead, as you fill a pitcher, you probably start out fairly slowly until the flow starts going, then gradually open the spigot all the way. As the water level starts getting to the top, you back off the flow rate to make sure you don’t overfill the pitcher and make a mess, eventually filling the last little bit with a trickle.That’s exactly how QC 3.0 works!A 3.0 charger “talks” with the device to coordinate the charge rate, and adjusts different voltage settings. All this results in “minimized losses, increased efficiency, and improved thermal performance.”Why Charge Up to 80% Battery Life? Smartphone batteries charge in two different phases:The first phase is from 0-80% and this phase absorbs huge amount of power at once.From 81-100%, the battery has to be careful of the power level it absorbs.QC 3.0 increases the process during the first phase four times faster than conventional chargers. Because of its algorithm, it can determine the power level it has to absorb when the phase changes.

Does not work as described.
You can not use both ports at the same time. Only one works at a time. If you plug 2 devices in one will work and the other will not unless you disconnect the active one and the other one will work.

only one worked
2 out of 3 didn't work

All 3 faulty after a couple months
After just a couple months of use. All 3 of these chargers became faulty. Roughly a 1/3'd of the time you connect your phone or a device to these chargers it will say it's charging without transferring power. For example, you plug your phone in before sleeping at 13%. Says it's charging. You wake up with your phone at 3% saying it's still charging. Beware fSCPA Co. products. Apparently they pump out some lemons.

very good quality. works for me.

Buyer beware!
All three stopped working after about 8 weeks. Great at first then they just stopped. Complete trash and a waste of money.

!!!DO NOT BUY!!!
Charger comes with two usb ports. However, if you try to charge two devices at the same time, it fails to charge properly and puts your devices at risk of damage. I really had high hopes for this charger and I'm very disappointed.

Not a QC 3.0
Low and behold I plugged in my phone and it does not recognize these as a fast charger as advertised. Don't want your money
