Sizing tools
Dash cam storage and loop time
How many hours of driving your memory card holds before the oldest clips are overwritten.
How it works: Hours = card GB × loop share × 8,000 ÷ (Mbps × 3,600). Vantrue's manual says loop recording uses 70% of the card; DashCamGuys measured 51.6 Mbps for the N4 Pro in 3-channel mode.

Jump starter size by engine
Pick the NOCO model rated for your engine.
How it works: NOCO rates the GB40 for gas engines to 6.0 L and diesel to 3.0 L, and the GBX75 for gas to 8.5 L and diesel to 6.5 L.
