Universal 18W car charger

The OtterBox 78-52703 is a compact USB-C car charger built for universal phone compatibility. It delivers up to 18W of power through a single USB-C port, supporting fast charging for a wide range of devices on the road.

12-24VDC input and PD 3.0 limits

The charger draws 12-24VDC from the vehicle socket, making it suitable for most cars and trucks. Its USB Power Delivery 3.0 implementation caps output at 18W using 5V/3A or 9V/2A profiles, so devices requiring higher voltages or wattages will not charge at their maximum speed.

Single-port 18W output decides fit

The single USB-C port provides a maximum of 18W, which determines whether this unit matches the buyer's needs. Users needing to charge multiple devices simultaneously or power laptops requiring higher wattage will find the output insufficient.

Questions about this item

Should I pick this 18W USB-C charger or a lower-wattage model?

Choose this 18W charger when your phone or tablet supports USB Power Delivery 3.0 and can accept 9V/2A; a lower-wattage model will charge the same device more slowly.

What does the 18W rating deliver once the charger is plugged into my car?

It supplies up to 18W through the single USB-C port — 5V/3A for most phones and 9V/2A for devices that negotiate higher voltage — so compatible handsets charge up to 3.6X faster than a 5W baseline.

The charger lists USB Power Delivery 3.0 — what does that cap in practice?

The PD 3.0 implementation caps output at 18W (9V/2A max), so any device requesting more power will only draw what this adapter can provide.
