Levererad strax under en månad efter beställning. Produkten mycket prisvärd, visar både ström och effekt i nedre fältet. För både spänning och ström kan värden justeras till skillnad från andra mätare jag köpt.

Ok ser ut som det ska ingen instruktion men man vet vad det är ett tips skriv egen innan du packar ner den jag skrev från 5 till 9 v

Äntligen kom den , det vad på tiden

Var trasig när jag öppnade paketet.

Item as described. Arrived quickly with 3 weeks delivery time. Many thanks to JOOM, the sales partner and the courier! Am satisfied! +++UPDATE +++: Yes, what should I say. The thermometer does what it's supposed to and it's on my desk in the office. Nice that it also shows the humidity! I'm still satisfied!

It's exactly what you'd expect, it shows the outside temperature nicely, by placing the sensor on the end of the wire outside, and the inside temperature, which is exactly where the thermometer is located. It is also very useful to find out the maximum or minimum temperatures in a desired range.

Very satisfied with this item. Works exactly as advertised. Very clear display. Instructions are easily understood. Extremely light. Inside and outside temps seem pretty accurate, as stated +- 1C, 1.8F. Well worth the price. Delighted. The tracking info was good, too. Would deal with JOOM again.

Works, voltage is correct... I measured it. However, the output power is unknown... So how many watts it can output if the feed is large enough from the 5 volt side. I tried almost half an ampere to 12 volts, that works.
