The length of the power bank is about 136.08mm.
The width is approximately 66.06mm.
The thickness is approximately 16.22mm.
The weight of the TEGIC 30W ice grid mobile power supply is about 235.8g.
Held in the hand, the volume is slightly larger.
Compared with the previous generation, the power and shape have hardly changed, and the chip position of the circuit board is reconstructed.
The back contrast is also a big difference.
The nameplate comparison on the side changed from power to capacity.
Contrast on the other side.
The top output connector and power key position are also consistent.
Product reviews
The appearance and size of the TEGIC 30W ice grid mobile power supply are introduced above, and the following enters the test link to take everyone to understand this charging treasure from the aspects of protocol, PDO and compatibility.
Protocol testing
This test module mainly tests the fast charging protocol supported by the charging treasure, and the user can match the output device according to the specific protocol, so as to obtain a better fast charging experience.
Using Chargelab's POWER-Z KT002 tester, read the fast charging protocol of the USB-C interface, and support PD, PPS, Apple 2.4A, Qualcomm QC2.0/3.0/4+ and other fast charging protocols.
In terms of PDO messages, it supports five sets of fixed voltages of 5V3A, 9V3A, 12V2.5A, 15V2A and 20V1.5A and a set of PPS voltage levels of 5V-11V3A, which has better device compatibility.
Read the fast charging protocol of the USB-A interface, and the actual test supports Apple 2.4A, Qualcomm QC2.0/3.0/, AFC, SCP, FCP and other fast charging protocols.
Charging compatibility testing
The compatibility test session can clearly know the TEGIC 30W ice grid mobile power supply for the charging of each device, and the charging head network will use dozens of devices with charging treasures for testing, presenting the reader with real test data.
