ESTONE 5V 3.4A Dual USB Car Charger Adapter Black

SKU CH-4W4V-1BEQV

Charges two devices at once with 5 V 3.4 A total output and a 60 W lighter socket

  • ColorBlack
  • Dual USB ports charge two devices simultaneously
  • 4 A combined output powers phones and tablets quickly
  • 12–24 V input works in cars and trucks
  • Built-in overcurrent fuse protects connected electronics
  • Fire-retardant housing resists high temperatures for safety

Dual-port car charger for phones and tablets

The ESTONE adapter plugs into a 12-24V cigarette lighter socket and provides two USB outputs rated at 1A and 2.4A for a combined 3.4A at 5V. It suits drivers who need to keep a smartphone and a tablet powered during the same journey.

Sustained output with dual fuse protection

An internal over-current fuse and a replaceable 6x25mm 250V 8A tube fuse guard connected devices during continuous charging sessions. Fire-retardant, high-temperature resistant housing helps the unit maintain stable delivery without overheating on long trips.

60W lighter-socket limit decides fit

The built-in socket passes through 12-24V at up to 60W, so it cannot run accessories that draw more power. Buyers needing to operate higher-wattage inverters or appliances must choose a different solution.

Questions about this item

How much heat or noise does the dual USB car charger produce when running all day?

The adapter uses fire-retardant, high-temperature resistant material and a built-in tube fuse to manage heat, and it has no moving parts so it operates silently.

What must my vehicle already have for this charger to work?

Your vehicle needs a standard 12 V or 24 V cigarette lighter socket to power the adapter.

Will the 5 V 3.4 A output safely charge an older phone that only draws 1 A?

Yes, the smart USB ports detect the device and deliver only the current it requests, so a 1 A phone charges normally without risk.
