The charger shows good voltage and current stability under changing load. The yellow line is a bit wider than the iPhone charger, showing a bit less regulation for a fixed load. Note that because this charger has a high current output, this chart has a different current scale than most of the charts to fit the whole trace in the image. The output from the Apple iPhone charger is surprisingly non-constant under load. The charger starts off with 5.2 volts with no load, dropping to 4.6 volts as the load increases, resulting in the downwards slope of the top yellow line. As the load increases, the current keeps increasing, resulting in the slope of the right yellow line. Note however that the yellow line is relatively thin, so the regulation is pretty good at each point. The KMS charger has fairly good output, with a small peak in the spectrum at the switching frequency. However, it has many large voltage spikes in the output, over half a volt, as can be seen on the right. The Belkin charger does well at eliminating ripple, but has a lot of noise otherwise.

It also uses a different variable voltage selection and negotiation protocol than USB PD, which Qualcomm advertises as better/safer for its own SoCs. Qualcomm’s Snapdragon SoCs are used in many popular smartphones and tablets. It’s fast-charging standard, Quick Charge, has been through multiple iterations. Fast-charging an iPhone requires the use of a USB-C to Lightning cable, which, until February 2019, needed Apple’s OEM MKQ42AM/A or MD818ZM/A USB-C to Lightning cables. Unfortunately, they’re a tad expensive at around $19 to $35 from various online retailers such as Amazon. It scales up from smartphones to notebook computers, provided they use a USB-C connector and a USB-C power controller on the client and host.

But, many people don’t actually know what micro-USB charging actually does, particularly when it comes to fast charging.

Take advantage of utilizing each and every charging port, connect all 16 ports without losing power to any USB device that is simultaneously connected.

China USB Chargers

The most eye catching is probably the 4.8 amps of dual power, which the device routes to each port as 2.4 amps per port. That is going to supply enough power to effectively charge up even tough, high amp batteries like those found in iPads and other tablets. Inside however, RAVPower has iSmart 2.0 charging technology. That in turn means that the charger can adapt the amp output to better match the device being charged – remember that not all devices are going to need those meaty 2.4 amps of power.

These additional connection allow to go for higher current without having massive voltage drop at the connection. Coupled with higher voltage, that gives a lot higher charging power.

The difference in price between models is minor when the device is priced on the basis of the number of ports. USB Type-C is backwards-compatible with older versions of USB A, but you will need an adapter that has a Type-C connector on one end and an older-style USB Type A port on the other end.
