SG Mini USB power supply output rating

[Deacon]

How many amps at 5V is the included power supply with the SGGCX2PRO rated to provide?

I have an extra and was thinking about using it to power other USB devices.

well devises will only pull what ever they need, so you cant force feed too many amps into something.

At least what I managed to find is a product picture on Amazon.
The adapter must provide power to connected devices with a current of up to 1 Ampere (5 Watts)

I realize that, and that’s not what I asked. I just asked what it’s rated to output. If I wanted to run a power-hungry device off it, would it keep up? That’s all I wanted to know.

Excellent, thank you. So rated at 1A max. Plenty for the job it was designed for, of course. Some actually are capable of providing more current than their rating, while for others the voltage drops off a cliff beyond that point (and crap ones never reach it), but I don’t ever choose to push things past their rating.

I found a different one on Amazon and went head and tested it and found that while it’s rated to provide up to 3A, I could actually push it past 3.5A without issue. That’s where I stopped, and I don’t know how long it would actually last without burning itself out eventually, but I’m satisfied for now

This is a very interesting device, but we are moving away from the topic.

Perhaps you should create a new topic like “Which USB power adapter 12V> 5V do I use in a car” in the DIY Projects section. The most valuable thing here is that users took measurements and confirmed or refuted the real performance indicators under the load of what manufacturers declared.

PS: could you correct the link to the adapter, it leads to another place?


PPS: I myself have several USB testers and load devices and follow the topic "Charger and Micro USB cable" on Russian 4PDA forum https://4pda.ru/forum/index.php?showtopic=605997, in which I find many useful tips and links. And although there are most of the tips on adapters 220V > 5V, automotive ones are also sometimes found.
Another very interesting resource from a tester from Denmark (lygte-info.dk), examples can be found here: https://lygte-info.dk/info/indexUSB UK.html and here: https://lygte-info.dk/review/USBpower Xiaomi Dual USB car charger CZCDQ01ZM UK.html

... I found it similar to AliExpress (Waterproof 12V 24V Motorcycle QC3.0 PD Type C Charger SAE to USB Adapter with Voltmeter & ON/Off Switch for Smart Phone Tablet G) only there is no SAE connector and the current is only 2.4A, but Fast Сharging is stated - QC3.0 and Type C - PD (but it seems to me that this is a fake, because the maximum power in the characteristics is indicated only 10 Watt = 2A)
