The 9to5Mac hands-on filed November 1, 2026, puts ESR's 45W Xtend wall charger on the desk. The unit rates at 45W but negotiates up to 60W through AVS, a protocol that 9to5Mac says unlocks the fastest charge speeds on the iPhone 18 Pro and 18 Pro Max. The desk's author, Michael Burkhardt, carried the charger for several weeks before writing, and ESR released the xtend line the month before, every unit shipping with a built-in retractable cable in a trend the desk notes has grown over the past year.

The spec table carries the figures, but it does not show the mechanical choice behind the cable: 3.1 feet of built-in length on the 45W unit, against roughly 2.2 feet on the rest of the xtend lineup. The charger also exposes a standard USB-C port, so the retractable mechanism is a convenience, not a lock-in, and a buyer can thread a longer cable through the port and ignore the built-in one entirely. Burgundy is the colorway ESR matched to the iPhone 18 Pro, which tells you the target buyer is already in the Apple ecosystem and wants the brick to look like it belongs in the same bag as the phone.

Die Brief's read: the pricing inversion is the story the table buries. The 100W car charger lists at $36.99, which is $13 less than the 45W wall charger at $49.99, and the document does not explain why a buyer pays more for less wattage. The 100W car charger carries two retractable cables plus an extra USB-A port, but the page does not state whether the 100W budget is shared across those outputs or allocated per port, which means the claim that it can "fast charge pretty much any iPhone, iPad, MacBook Air, or base 14-inch MacBook Pro" is a marketing sentence, not a spec.

What the page leaves open is a long list: no measured charge speed, no cable material, no dimensions, no weight, no safety certification listing. The AVS negotiation path is described in one sentence but not benchmarked against a reference charger or a stock Apple adapter, and the 20% discount on the burgundy colorway and the $20 discount on the car charger are Amazon-specific and will not hold through the holiday window. The document is a hands-on impression from a single desk, not a lab report, and every wattage figure it states is ESR's own rating, not an independent measurement.

The xtend line positions ESR against the stock Apple adapters that ship with iPhones, and the retractable cable is the differentiator a $30 Apple brick cannot match. But the 45W-to-60W AVS jump means the charger's headline number is not its ceiling, and a buyer comparing it to a 65W or 100W GaN adapter from a different vendor is comparing a floor to a ceiling.

The pricing inversion between the 45W wall charger and the 100W car charger is the structural problem the spec table hides. The document does not prove that the 100W car charger can actually deliver 100W to a single port, and without that figure the product lineup is a marketing arrangement, not a power architecture.

No measured charge speed, cable material, dimensions, weight, or safety certification appears in the document.

The 45W rating is a floor, not a ceiling, because AVS negotiation pushes output to 60W. The 100W car charger's per-port allocation is unstated, so the multi-device fast-charge claim is unverifiable from this document.
