UGREEN 60712 84W Dual Port Car Charger (Space Grey)

Eighty-four watts is the figure on the front of this listing, and every wattage underneath it is a total. Total USB Output is 24W. Extended Socket Output is 12V/60W. Total Output is 84W on twelve volts and 144W on twenty-four. Twenty-four and sixty make eighty-four, so the headline is those two added together — and not one line anywhere gives the output of a single port, which is exactly the figure that matters once two things are plugged in.

The narrative and the specification list describe different chargers

The description opens on 20W Dual PD Port Fast Charging and talks throughout about charging two USB-C devices at full speed. The specification list underneath names one USB-A output with three voltage-and-current profiles, a total USB figure, and an extended socket that passes twelve volts straight back out. A dual USB-C Power Delivery charger and a single USB-A charger with a pass-through socket are different products. Both accounts are printed here, neither has been chosen, and we have written in nothing to reconcile them.

Sixty of the eighty-four are the socket

UGREEN's own list separates the two: a USB output of 24W and a socket output of 60W at twelve volts. Only the first of those is attached to a USB port anywhere on this page. The larger half is the extended socket. A separate line lists the devices the charger is said to suit — a GPS, a dash cam, a vacuum cleaner, an MP3 player — without saying which of the two outputs any of them belongs to. Read the eighty-four against another charger's figure with that split in mind, because this page supplies no per-port number to compare instead.

Key features

• Goes in the twelve-volt socket: the only installation line on the page says to plug it into the car's power socket.
• Socket handed back: an extended socket output is listed at 12V/60W, rising to 24V/120W maximum.
• USB-A profiles: the one USB output is specified as 5V/3A, 9V/2A and 12V/1.5A.
• Status light: an LED indicator is credited with showing connection status and finding the ports in the dark.
• Scratch-resistant shell: the case is described as alloy with a scratch-resistant surface, in a line that stores the two words run together.
• Sprung contacts: a shrapnel contact design is said to keep it seated over rough road.
• Managed internally: a power management chip is credited with over-temperature, over-current, over-charging and over-voltage protection.

Read before you buy

• The 20W claim and the three USB-A profiles are never reconciled. The profiles are given as volts and amps and the page states no watt figure for any of them.
• An entire paragraph is stored twice, word for word, at the end of the fourth section. The page therefore makes fewer distinct claims than its length suggests.
• The last item on the page stops mid-sentence, at Convenience: LED indicator for easy. What followed is not recoverable from anything here and has not been guessed at.
• The protections are listed without a single threshold, cut-out point or reset behaviour beside them.
• The case is sold on being thumb-sized and is never measured: no millimetres, no centimetres, no mass, nothing.
• Neither the model number nor the colour that the product name carries turns up in anything UGREEN wrote below it.
• There is no contents list, so nothing states whether a cable comes with it.
• No approval, certification or compliance mark of any kind is claimed for a device that sits in a vehicle's electrical system.
• Not one of the wattages, voltages or currents is given a margin, and no allowance sentence exists on the page for one to hang off.

Wanting a socket splitter with a USB port on it, you will find the specification list describes exactly that, and describes it clearly. Wanting the two-port USB-C charger the opening paragraphs sell, you will find the specification list does not support it. We have published the weaker reading.
