I have an LED desk lamp
powered by a USB adapter. The adapter specs are
Input: AC100-240V
50/60 Hz 0.6 A
Output: 5.0V ----2000mA
Light stated to blink and stopped turning on. Checked the USB plug and the power brick was very, very hot. It over heated.
Light still works if plugged into my computer USB port. My question is, with the specs as stated will it cause any damage to the computer?
Supposedly it has a 4-year warranty. I put in a claim, and they only asked for the brand, what was wrong, my Amazon account. Without asking about proof of purchase (but apparently, they have a record) they immediately refunded $35.99 into my Amazon account to buy a replacement.
Since the light works, I plan on buying just a replacement power USB adapter brick of the same or close specs.
That 5.0v & 2.0A phone-charging standard is common for cellphones newer than about 5 years old or so.
IIRC my Samsung LTE phone from 2015 had a 2.0-amp charger. You can probably scrounge through a thrift shop and find plenty of 5-volt 2-amp power cubes.
The early USB 2.0 standard was 0.5-amps, bumped up to 1.0 then 2.0, until now USB-C will push 5.0-amps at 5.0-volts. So, old equipment might want to draw more than 2.0-amps, but newer computers & power cubes will limit the current to avoid damaging the device.
One of the more useful things I've found are the multi-outlet plates that come with USB plugs.
For the cost reimbursement of the unit, I'm buying new power brick along with several other electronic accessories I need. I have a number of accessories already attached to the computer. Best I do not push it any further.
Thanks guys.
Well, it DOES make sense to sort through those old 'power cubes'.
Example, I just finished switching family phones, tablet, and earbuds over to wireless charging.
Actually quite convenient, the charging antenna fits nicely under the phone/tablet case.
BUT, then had a tablet that stopped charging- tried everything.
Eventually realized that, in trying to 'clean up' the clutter of USB chargers / 'power cubes / wall warts,
I had a 2.0A wireless charger being fed by a 1.0A supply.
So, check the ratings on those USB chargers, oldest I have is a charger for a Samsung 'candy bar' form phone that only puts out 0.55A, followed closely by LG & Samsung that only put out 0.7A.
[color=#000000]Hello,[/color]
[color=#000000]I am working to replace a NuTone fan timer with a Leviton LTB60-1LZ and the wiring is throwing me for a loop. Admittedly, I am no expert in wiring![/color]
Pics (as PDFs) are attached. My main questions are:
1. how do I tell line (hot) from load when they are blue and black?
2. Am I reading the wiring instructions right that I need to connect the white from the new fan switch into the bundled white wires in the wall?
3. I don't have a ground that I can see-- is that a problem?
Anything else I am missing?
Thanks!!
Ben

[color=#383a3b]I have a couple small speakers that are OLD - from 2005? But they work and I'm not looking to spend too much (or anything) to mount them on the wall.[/color]
[color=#383a3b]They have a single threaded hole on the back of each one. I have screws that will go in there.[/color]
[color=#383a3b]Any (inexpensive) recommendations on a way to mount them on the wall other than a little shelf for each? Only thing I can think of is either something like a round thumbscrew that fits in a slot in a clip mounted on the wall (think a mic and mic clip on a CB radio good buddy!)[/color]
[color=#383a3b]Or a U bracket like in picture? And I don't see that in home depot.[/color]
[color=#383a3b]Anything else?[/color]
