Meter 6-30V LCD Volt, Amps, Capacity % + Level Indicator:
Specifications:
Input Voltage: 6-30V DC (Note: The USB port is a step-down power supply. If your input voltage is less than 12V, you cannot support 12V fast charge, and the same is true for 9V fast charge)*
Battery Display: 7-Segment Display - 13% 26% 39% 52% 65% 78% 91%
Output voltage: 5V by default, automatically adjusted between 3-12V after triggering fast charge
Output power: Up to 24W (5V@4A, 9V@2.5A, 12V@2A, etc.)
LCD Colour: Blue
Size: 71.3 x 38.7 x 26.2mm
Installation Size: 75 x 39mm
Features:
1. Input reverse connection protection, reverse connection does not burn the module
2. Dual independent USB, using IP6505T fast charge identification chip, support mainstream fast charge protocols such as QC2.0 / QC3.0 / FCP / SCP / MTK / APPLE. The USB port fast charge function requires mobile phone cooperation and cannot be activated every time. If it cannot be activated, please plug and unplug a few times. The chip supports mainstream fast charge protocols, but cannot support all the fast charge protocols on the market. Because fast charge is related to many factors such as mobile phone data lines, mobile phone models, mobile phone power, and protocol matching degree, it cannot guarantee that every mobile phone can charge fast.
3. Supports multiple battery types, battery type and string number can be set (default 12V lead-acid battery) Please select the corresponding option according to the type of your battery and the number of cells in series. Ordinary lithium batteries and ternary lithium batteries are generally nominally 3.7V / cell and fully charged to 4.2V. The lithium-ion battery is generally nominally 3.2V / cell and fully charged with 3.7V. Lead-acid batteries are generally rated at 12V / block and are charged at 13.8V-14.5V.
