Effect on Battery

Quick charge becomes very important in various fields - EV and Mobile Computing. I wonder whether there is any long term effect on the battery especially in the life of the battery.

Yes it is true, that this improvement in the efficiency will add to the cost of the chargers as compared to the USB Chargers, but at the same time people will surely go for at-least one of this kind to enable them their fast charging needs in emergency conditions.

This is a major release for Dialog. 88 percent is a significant number and demonstrates what can be done in this space with some serious investment.

Is common USB good enough?

I would be more certain that this will take off if it weren't for the standardization of power cords on microUSB. Granted, they are a minor irritant when you get them upside-down (seems like at least 75% of the time) but that is a lot better than having a separate and expensive unique cord for each device. I was surprised to see up to 88% efficiency, but the flip side is that I can only charge on a wireless station. USB power cubes are cheap enough to just buy several.

LATEST ARCHIVED BROADCAST
As data rates begin to move beyond 25 Gbps channels, new problems arise. Getting to 50 Gbps channels might not be possible with the traditional NRZ (2-level) signaling. PAM4 lets data rates double with only a small increase in channel bandwidth by sending two bits per symbol. But, it brings new measurement and analysis problems. Signal integrity sage Ransom Stephens will explain how PAM4 differs from NRZ and what to expect in design, measurement, and signal analysis.
