{"title":"Power Bank KeepAlive (USB-C)","handle":"power-bank-keepalive-usb-c","url":"/products/power-bank-keepalive-usb-c","description":"The Power Bank KeepAlive (USB-C) prevents power banks from automatically shutting off when connected to low-power devices. It uses a 555 timer circuit to pulse a small amount of current through the USB-C port, keeping the power bank active even when drawing minimal power.\n\nThis assembled SMD version uses dual USB-C female connectors — connect it between your power bank and device using USB-C to USB-C cables. The data lines pass through unaffected, so charging and data transfer work normally. No soldering required.\n\nKey Features\n\n\nKeeps Power Banks Alive – Prevents auto-shutoff with low-power devices\n\n555 Timer Circuit – 50% duty cycle, ~10mA average with ~100mA pulse\n\nDual USB-C Female – Both ports are USB-C for cable-based connection\n\nData Pass-Through – Data lines connected directly and unaffected\n\nUltra Compact – SMD construction for minimal size\n\nPre-Assembled – Ready to use, no soldering required\n\n\nIdeal For\n\nPowering Raspberry Pi Pico and small microcontrollers from power banks\nLow-power IoT devices on portable power\nCharging low-draw devices like earbuds\n\n\nPackage Contents\n\n1× Assembled KeepAlive (USB-C version)\n\n\n\nNote: USB-C to USB-C cables are required and not included. Compatibility varies between power banks — the KeepAlive is designed to work with most, but results may differ depending on your power bank's shutoff threshold.\n\n\nResources\n\nDocumentation\nTroubleshooting Guide\n","vendor":"PiHut","product_type":"physical","in_stock":true,"options":[],"variants":[{"id":212,"title":"Default Title","sku":"PH-106133","mpn":"106133","price":14.95,"compare_at_price":0.0,"on_sale":false,"in_stock":true,"available_quantity":103,"option1":"Default Title"}]}
