Your car charger matters more than most people realize — a weak or generic one can leave your phone barely charging while running navigation. Here's what to actually check. For a detailed comparison of top car chargers with prices, see our best car chargers in Pakistan guide.
Short Answer
Look for a PD (Power Delivery) or QC (Quick Charge) car charger rated at least 20W per port, with a genuine cable rated for the same wattage. A cheap car charger with a low-quality cable is the most common reason phones charge slowly or not at all while driving.
Why Car Charging Is Often Slower Than Wall Charging
Car cigarette lighter sockets typically supply less stable voltage than a wall outlet, and many budget car chargers cut corners on the internal circuitry to hit a low price point. Combined with running GPS navigation (which drains battery faster than normal use), an underpowered car charger can result in your phone barely holding charge, or even slowly losing charge, during a long drive.
What to Check
- Wattage per port: single-device chargers should be 20W+ for modern phones; dual-port chargers split power, so check the per-port rating, not just the total
- Cable quality: a thin, generic cable will bottleneck even a good charger — use a cable rated for the same wattage
- Protocol support: PD (USB-C Power Delivery) works across iPhone and most Android; QC (Quick Charge) is Android-specific
Signs Your Car Charger Isn't Keeping Up
- Battery percentage drops during a long drive with navigation running, despite being "plugged in"
- Charging is noticeably slower than the same phone on a wall charger
- The charger or cable feels warm to the touch during use
For reliable in-car charging, pair a properly-rated USB-C cable like the Apple USB-C to C Cable or Anker 310 cable with a PD-rated car charger. Browse the full Anker Pakistan catalog and Baseus Pakistan catalog for all available car charger options.
