Introduction

A few months ago, ChargerLAB reported on the launch of the No. 30 Power Bank by CUKTECH at the Hong Kong Electronics Show. You can check the news here. In summary, this No. 30 Power Bank is considered the successor to the highly acclaimed ZMI PowerPack No.20. Naturally, many people were curious about the charging compatibility of No.20, so we have compiled the data from the ChargerLAB Compatibility100 test, presented in both text and graphics, for a better understanding.

ZMI PowerPack No.20 Power Bank, as the flagship product of ZMI, boasts a maximum output power of 200W, a capacity of 25,000mAh, and is equipped with five 21700 batteries. These batteries offer improved individual capacity, energy density, and charging/discharging performance compared to traditional 18650 batteries. Moreover, in terms of safety, it incorporates multiple temperature protections and circuit safeguards. Let's now explore how this flagship ZMI power bank performs in terms of charging compatibility.

The packaging box contains two cables, one is a dual USB-C cable.

The other one is a USB-C to USB-A cable.

ChargerLAB POWER-Z KM003C shows the USB-C1 port supports FCP, SCP, AFC, QC3.0, PD3.0, DCP and Apple 2.4A protocols.

And it has five fixed PDOs of 5V3A, 9V3A, 12V3A, 15V3A and two sets of PPS.

Charging Compatibility Test

Next, ChargerLAB will do the compatibility tests on a diverse range of 100 devices, such as smartphones, game consoles, wearable devices, tablets, and laptops with the USB-C1 port. These tests aim to simulate everyday charging scenarios, allowing everyone to gain valuable insights into optimal charging techniques.

Mobile Phones

Starting with smartphones as always, we can see that most models triggered a 9V voltage value, while Xiaomi devices reached even higher levels, with 16-18V. Only a few models operated at 5V.

Drawing a bar chart allows us to visualize the charging power of each model more clearly. As ZMI was originally a part of Xiaomi, all Xiaomi devices successfully triggered the proprietary charging protocol, achieving 40W or higher charging power. The Redmi Note11T Pro+ topped the charts with a charging power of 85.94W, followed closely by the Black Shark 4S with 85.26W. Among other brands, Samsung, Apple, and Meizu models displayed power levels ranging from 20-30W, which is not too shabby. The remaining models fell within the 10-20W range.

Game Consoles & Wearable Devices

Next we have the game consoles and wearable devices, the game consoles triggered 15V and 20V voltage values, while wearable devices triggered 5V.

Again, drawing a bar chart, the game console section revealed that the AYANEO Air had the highest charging power at 37.36W, followed by the Steam Deck with 29.38W. The Nintendo Switch reached 14.75W, and the power bank can trigger the TV mode for Switch, fully meeting the gaming console's charging needs. As for wearable devices, the Apple Watch Ultra reached a charging power of 5W, and the other devices fell within the normal range.

Tablets

Moving on to tablets, Apple products triggered a 15V voltage value, while Android tablets were lower at 8V, as usual.

Once again, we represented the data in a bar chart. The fourth-generation 11-inch iPad Pro had the highest charging power at 27.32W, with all Apple tablets performing above 20W. The lowest was the Redmi Pad at 17.08W, while other models fell within the 20-26W range.

Laptops

Finally, let's look at the performance of laptops. All eight models tested triggered a 20V voltage value, with current ranging from 3-5A.

The bar chart for laptops showed that the 16-inch MacBook Pro M1 Max had the highest charging power at 91.41W, followed by the HP ProBook 450 G10 with 89.13W. Both MacBook Air models achieved charging powers of around 69W, while the lowest was the Lenovo IdeaPad 5 at 48.21W. Overall, all tested laptops demonstrated commendable charging power.
