Pros and cons

Pros

The claimed 100W USB-C1 output offers a higher-power option for compatible USB-C laptops.
The listing names USB Power Delivery and QC among supported charging protocols.

What to know before buying

Listing details to confirm

The listing has inconsistent or unconfirmed electrical details: its stated 120 volts, 15 A and 120 output voltage do not align clearly with its claimed standard 12V and 24V vehicle-socket compatibility. It also advertises iPhone 18 Pro Max charging in the title and feature text but lists iPhone 17 Pro Max under compatible phone models. Confirm the intended vehicle fit, electrical ratings, model compatibility and whether the black-with-240W-cable variant is selected before buying. The listing's rapid-charge timing and heat-management statements are manufacturer claims, not independently verified results.

Who is it for?

A good fit for

Drivers seeking multiple USB charging ports, including a high-output USB-C port for a compatible laptop.
People who want to charge phones and smaller USB devices alongside a laptop during a drive.

Less suited to

Buyers who need the full advertised 136W available to a single port or simultaneous full-rate charging on every port.
Buyers who need settled electrical ratings or confirmed compatibility with a specific phone model without checking the listing variant.

Aggregate ratings lean strongly positive, with most ratings in the five-star category, but a smaller share are lower.

They cannot confirm the advertised 100W laptop output or resolve the listing's electrical and phone-compatibility inconsistencies.

Is it compatible with iPhone 18 Pro Max?

The title and feature text refer to iPhone 18 Pro Max, but the compatible-phone-model field names iPhone 17 Pro Max. Confirm compatibility for the exact phone and selected listing variant.

Will it fit a 12V or 24V vehicle socket?

The feature text claims compatibility with standard 12V and 24V vehicle sockets, but the details also list 120 volts and 15 A. Verify the electrical specifications and fit before purchase.
