I Upgraded My $30 DIY Dashcam Power Bank — 3X Faster Charging! #diy #powerbank #dashcam

I upgraded my $30 DIY dashcam power bank prototype into a finished, fast-charging unit for just $60 total—roughly 20% of the cost of commercial alternatives! By adding a dedicated 2A LiFePO4 charging board, a 12V-to-5V step-down converter, active push-fan cooling with custom heatsinks, and a 3300µF capacitor for stable power, this pack now tops off from 20% to 80% in about an hour (3X faster charging). It features XT30 connectors, thermal switch protection, and an anti-rattle rubber base, making it a true "install and forget" setup hidden right under the dash. It has been running reliably in 24/7 parking mode without any issues! #diy #dashcam #lifepo4 #Dashcamsetup #parkingmode
