UGREEN 90645 63W USB-C Car Charger

Every watt on this page is a watt coming out. Sixty-three altogether, forty-five to the USB-C port and eighteen to the USB-A, and the three agree exactly. What the charger draws in is never set down. Input voltage, input current and fuse rating are all missing, which leaves what your socket must supply unstated, along with the behaviour of this charger on a circuit that cannot supply it.

Where the sixty-three watts go

The split is the useful part and this page gives it. Forty-five watts go to the USB-C port, which is where the PPS, PD 3.0, QC 3.0 and FCP fast-charging support sits, and eighteen to the USB-A. Samsung Super Fast Charging 2.0 is claimed for the C side, with backwards compatibility down to 1.0 devices, and a long run of handsets, tablets and laptops gets named. Left out entirely is whether both ports hold those figures while both are working.

One adapter, or two ports

Written from end to end about a two-port charger, the description opens on a heading naming a dual-port unit and a sentence offering to charge two devices at once. The search summary carried by this same product describes a compact, single-port adapter. Both accounts sit on the one product. We have followed the description, being the fuller and more particular of the two accounts, and the disagreement is real enough that you ought to know about it.

Key features

• Fast side, 45 W: the USB-C port, and the one carrying the protocol support.
• Second output, 18 W: the USB-A port, taking a phone or a dash camera alongside.
• Four protocols named: PPS, PD 3.0, QC 3.0 and FCP.
• Samsung fast charging: Super Fast Charging 2.0 is claimed, with 1.0 devices also supported.
• Spring-clip retention: the supplier reports a 3000-plus plug and pull test in the cigarette lighter outlet.
• Locator light: a blue LED so the socket is findable in the dark.
• Vented polycarbonate shell: described as scratch-resistant, with an opening the supplier calls a Thermal Hole.

Specifications

• Both ports together: 63 W
• USB-C output: 45 W
• USB-A output: 18 W
• Charging protocols: PPS, PD 3.0, QC 3.0, FCP
• Case plastic given as: PC
• Socket it fits: the cigarette lighter outlet
• Model in the name: 90645

Claims we have left standing as the supplier's

• Whether the two ports still deliver 45 W and 18 W under simultaneous load, or divide some smaller budget, is never addressed.
• The wording used is UL tested. UL listed would be a different and stronger claim; we have carried the wording the supplier actually used.
• RoHS, CE and FCC each get named. None among the four marks arrives with a standard number attached.
• Protection against over-current, over-voltage, over-heating and short-circuiting is asserted, and no threshold or figure stands behind any of the four.
• Input voltage, input current and fuse rating are missing from every part of this product. One mention of a 12V socket sits up in the search summary, and nothing numeric attaches to the supply side anywhere below it.
• Dimensions and weight are unprinted, for a plug whose entire job is seating in one particular hole.
• A cable is never mentioned, so whether one ships with the charger stays unanswered.
• Model number 90645 is stamped across the title, the handle and both search entries. Inside the description it never appears at all.
• UGREEN's name is on the charger; a warranty term and a place of manufacture are not.

Buying this to run a laptop and a phone from a single socket, plan around 45 and 18 as separate budgets rather than around the combined 63.
