The PD3.0 fast charging standard power output limit is currently 20V5A, and the power is limited to 100W, although it has been applied in most digital products, but it cannot meet the power demand of high-performance notebooks. Apple's Macbook Pro 2021 uses the new PD3.1 fast charging standard to achieve 140W universal fast charging support, but the original 140W charger is large in size and has few interfaces, which is difficult to meet the needs of users.
On December 30, 2021, SHARGE Flash Pole, which has created a number of high-power portable charging explosive products, released the new SHARGEEK Exploration Pioneer Series S140 charger and 130W visual power bank - Blade Exploration Edition. In response to the needs of Macbook Pro 2021, the first PD3.1 140W multi-port charger was introduced, which is smaller, lighter, more interfaces, and more extensive compatibility. The SHARGEEK S140 charger uses the PD3.1 fast charging standard, and with the new EPR data cable, it can provide up to 28V5A power output with a power of up to 140W, breaking the PD3.0 100W power limit.
SHARGEEK S140 charger is set up with three output interfaces, two USB-C + a USB-A, which is commonly known as the 2C1A gold collocation, in addition to providing fast charging support for mainstream digital products, different interface types are also compatible with different cables and new and old equipment, while also taking into account the use of multi-device simultaneous charging needs.
Powerful performance does not lead to larger volume, SHARGEEK S140 charger using the third generation of semiconductor - GaN (Gallium Nitride) technology, with a three-dimensional stack design, three-dimensional size of only 73mm X 73mm X 28mm, power density of 0.93W/cm. Compared with the Apple 140W charger, which is also PD3.1, the SHARGEEK S140 charger is reduced by 25% in size and has flexible interface configurations.
The SHARGEEK S140 charger uses a digitally programmable controller from MPS (Silicon Systems Corporation) to greatly reduce switching losses and further improve power conversion efficiency. At the same time, the flash pole optimizes the traditional PFC+LLC architecture, combines digital control means to achieve zero voltage switching and zero current switching, reduce loss and improve efficiency, and achieve higher efficiency than similar products.
Traditional chargers are often accompanied by high heat when faced with ultra-high power output. In view of this problem, the Flash Pole Laboratory through thermal simulation thermal simulation, the combination of "space silicone" thermal conductive materials, structural optimization and shell stripes and other innovative designs, give full play to the performance of convection heat dissipation, radiative heat dissipation, so that the SHARGEEK S140 charger in high power charging, still maintain a low temperature.
Charging head net summary
SHARGEEK S140 charger supports the new generation of PD3.1 fast charging standard, supports 28V5A power output, up to 140W output perfectly adapts to the Macbook Pro 2021 full power fast charging requirements, and is backward compatible with PD3.0, PD2.0, most of the digital devices on the market.
Relying on gallium nitride technology, stereoscopic stacking technology, and PFC+LLC architecture, the SHARGEEK S140 charger has an ultra-high power density of 0.93W/cm, and high power can also be kept small and lightweight. 2C1A three-port output is a very flexible interface configuration, taking into account the needs of ultra-high power fast charging and multi-device charging, but also better support the use of different cables for new and old equipment.
SHARGEEK S140 charger priced at 499 yuan, has now landed on INDIEGOGO crowdfunding, the conference limited time special price of 399 yuan, domestic spot sale time in March 2022.
At the same time, the new 130W visual power bank was also released at the press conference, which continues the appearance design of the transparent cyberpunk of the previous generation of products, using a metal frame cleverly designed to meet various uses such as heat transfer and structural support, and has a large capacity of 20,000mAh to carry on board. Maximum support 130W output, can meet the notebook, tablet, camera, drone and many other devices charging, USB-C and USB-A two interfaces can support two devices simultaneous fast charging.
The 130W visual mobile power supply is priced at 999 yuan, and has now landed on the Kickstarter crowdfunding platform, and the limited-time special price of the conference is equivalent to 899 yuan, and the domestic spot sale and sale time is February 2022.
