It’s a great day for fast charging enthusiasts as Infinix, a brand that I think is an underdog that actually has good products based on my past experience reviewing their products – came out and announced that they have something called an “All-Round FastCharge” solution developed.
As the name suggests, it is literally an all-rounded fast-charging solution for both wired and wireless charging. Infinix aims to include intelligence in this charging solution to provide rapid and safe charging, while being flexible and smart – not sure what the latter two means, but we’ll have to test it out when it eventually ends up in a consumer product.
What Infinix did tell us is that the All-Round FastCharge is created to accommodate wired/wireless fast charging, wired/wireless reverse charging, bypass charging, smart charging, secure charging, and multi-protocol charging. This is a big claim, especially the multi-protocol support.
The details that Infinix told us stated that it is using a 4-pump parallel design for its charging architecture. We further questioned if it is using a multi-cell battery, but the answer we got is a bit more technical. Quote:
- 4-Pump Intelligent Circuit Design，each 4:2 charge pump supports a maximum of 80W charging power.
- Intelligently regulate the number of charge pumps required for different fast-charging wattages.
- 4:2 charge pumps support 98.5% extremely high conversion efficiency.
- Adaptation to more fast charging specifications, wider adaptation to user products
- Reasonable allocation to improve conversion rate and save energy consumption
From what I understand, each pump is capable of 80W and the 4:2 ratio is to combine 4 pumps into 2 bigger pumps, hence 160W each. Technically, the total power should’ve been 320W but limited to 260W – possibly for safety purposes.
We were told that the charger also employs the AHB circuit architecture (Advanced High-performance Bus) to output a higher power density while being physically smaller in size.
Then, we asked one more important question – is this going to be a proprietary charging standard or going to partially support the USB-PD charging standard – and the answer is that Infinix can’t provide any information about it now. A bummer – but I think it’s for the better. Save the surprise for when we finally get to review an Infinix phone with this All-Round FastCharge technology.
