Cumple muy bien con lo que ofrece puedo saber por el voltimetro la salud de la batería del vehículo cuando está apagado y la salud del alternador cuando lo enciendo, además que con su termómetro integrado puedo ir ajustando de mejor manera la intensidad del aire acondicionado.

Celsius, Not Fahrenheit
This device works as advertised, however I mistakenly assumed it read the temp in Fahrenheit. But the display is crisp and bright, easy to read even in the daytime, and doesn't noticeably drain the battery.

Cheap, convenient
Many cars don't have a voltmeter (useful to know the condition of your battery) nor an inside thermometer. This thing, installed in one second, shows you these two numbers... for $9.00. A bargain.

Caution: Celsius/Centigrade Only
As advertised- but thermometer is Centigrade/ Celsius only. Inconvenient for U.S. residents!

It works good
It does the job it was made to do by reading your voltage but I had a brain fart and overlooked the fact that this reads celcious temperature. Oh well, did not buy it for temperature any ways. I bought it so I can watch my power hog amp suck down the battery and make sure the alt is keeping up with it. Mission accomplished !!! 😂😂😂

Also ich habe mir das Gadget gekauft um zu sehen wie sehr die Batterie leidet wenn man nur noch Home-Office macht und 1x pro Woche 5 km fährt sowie um zu sehen wie hoch die Innenraum Temperatur vom Auto ist. Zum einen habe ich in der Wohnung das Gerät an einem Konverter angeschlossen um zu sehen wie genau die Temperatur Anzeige ist. Es waren meist 0,5-0 Grad Differenz. Das Gadget reagiert immer sehr schnell, wobei ich glaube das der Haus Außenkontakt eventuell nur einmal pro Minute nachmisst. Aber selbst wenn finde ich 0,5 Grad bei dem P/L Verhältnis noch gut. Die Voltanzeige funktioniert auch ganz genau. Da mein 12 Volt Anschluss nur Zündungsplus hat könnte ich nur das Testen. Hier verhält es sich so, dass er auf eine Dezimalstelle genau anzeigt. Einzige Einschränkung ist, dass er hier nicht auffinden sondern einfach die Hundertstel weglässt. Das es dir pessimistische Sicht ist, finde ich es besser so als aufzurunden. Also zumindest nach den ersten zwei Tagen bin ich zufrieden mit der anzeigt und das man die Aufkleber an der Seite einfach entfernen kann.

I think the temp is a bit off. Would be nice if I could set it

A useful,neat item.Saves rigging and wiring a dashmounted volmeter,and good to be able to monitor battery voltage constantly,the cabin temperature indication useful too.Not expensive and very prompt delivery,will buy again for our spare car.

finition et affichage assez joli, ce tester n'est malheureusement pas précis, il affiche une différence de 3 à 4 degrés, utilisé à moto, la température est assez correcte à l'arrêt par contre, enfin le voltage est aussi sous estimé, donc retour
