Tiger is a chain of shops in Europe that sell a range of gimmicky stuff for the home. I saw they had some fairly stylish looking USB chargers in a range of colours, and bought one to assess for construction quality.
It's actually pretty good. There's some basic filtering on both the mains input and the DC output, and the separation and transformer design looks quite acceptable for this style of device.
I ended up buying a couple more, as USB chargers are a very useful power supply to have. Especially if they are actually safe and have a stable output like these seem to have.

Not often that USB power supplies will actually exceed their labeled output rating. Most dodgy chargers won't get anywhere near it's rating – i have seen examples where it claimed 3A but couldn't even supply 1A!
I would not call those power supplys, but voltage supplys. They did not give steady power, but steady voltage.

Once you opened it up and I saw lots of electronic bits I figured it had to be better than Chinese average. Nice to see they actually put effort into it after watching the rest.
TIger is Danish. We tend to pronouce it as: Tea-er / Tee-ah
Do you think the iPhone chargers from tiger; USB to Lightning Cable; do you think it can harm my phone? I've heard cheap cables can mess up your phone and damage it. You seem to know this stuff. Advice? (It seems well, and I personally like it)
I'm wondering if these are the same as the USB chargers being sold under the "threesixty innovations Ltd" brand, by Wilkinsons/Wilko. Same spec, same bright coloured cases and actually less prone to voltage drop than most of my genuine phone chargers.
ooh, i have that Tiger shop really close to me, fun shop indeed 😀
We have capability to -90 C on our thermal chamber.
Yes, has to operate from -55 C to +125 C
Very common. We just did a four USB port, 10 amp charger with power factor correction and full emi filtering at work and used two tlv431's for the feedback circuit. The second was set only to operate as a overvoltage protection circuit.
Is the reference feedback chip a tlv431? Agreed on setting the output voltage to 5.25 volts.
Where did you buy it? Is there other connectors too? (EU etc)
I was expecting the typical cheapo unit inside. These are ( crapxon aside or even worse brand caps) not too bad, and might do well as generic 1A supplies. Would not like to draw more than 500mA long term though, the diode on the secondary side would likely be close to failing if you draw long term at more than 500mA, as it is likely only a 1A unit.
