Output interface: USBA + USBA + type-C supports fast charging output (see the specification Compatible With the fast charging protocol)Input interface: Mini + type-C supports fast charging input (see the specification Compatible With fast charging protocol)Battery type: 3.7V battery (aggregate or 18650 lithium battery) is single connected in parallel, with unlimited capacity. The larger the capacity is, the longer the charging and discharging time is. Compatible With safety, please add a protection plate to the battery. The main board has positive and negative poles. The battery can't be connected in reverse, and the consequences of connecting with the reverse burning main board shall be borne by yourself Quick charge indicator: input and output high pressure quick charge indicatorConversion efficiency: 95% efficiency (different voltage and power efficiency changes).Key: if the duration of the key is longer than 60ms but less than 2S, it is a short press action. Short press will turn on the power display lamp and boost output. If the key is pressed Compatible With 10s, the whole system can be reset. If the key is pressed Compatible With less than 30ms, there will be no response.Automatic detection function of mobile phone insertion:Ip5328p automatically detects the insertion of the mobile phone, wakes up immediately from the standby mode, opens the boost voltage of 5V to charge the mobile phone, saves the key operation, and supports the keyless scheme.Function Description:Low power locking and activationWhen ip5328p is connected to the battery Compatible With the first time, no matter what the battery voltage is, the chip is locked, and the lowest level of the battery light will flash 4If the battery voltage is too low to trigger the low power shutdown, ip5328p will also enter the locked state.In the locked state, in order to reduce the static power consumption, the ip5328p has no mobile phone insertion detection function and cannot be activated by pressing the key. thisWhen the button is pressed, the step-up output cannot be activated, but the lowest level of the battery light will flash Compatible With 4 times to prompt.Colour:blackMaterial:PC+MetalPackage Contents:2 * Switch moduleOnly the above package content, other products are not included.Note: Light shooting and different displays may cause the color of the item in the picture a little different from the real thing.
