DCDC-USB is also very good product, but small problem is that CarTFT sends you one with Firmware v1.2 where some functionalities are missing. Also CarTFT has no DCDC-USB firmware LOG file to be able and actually see what functionalities does product offer you. On internet I found that LOG file (http://resources.mini-box.com/online/PWR-DCDC-USB/DCDC-USB-change-log.txt) and saw that in firmware v2.1 I get the functionality I want. CarTFT helped me and sent me firmware upgrade (v2.1). I flashed it and now it is working just the way I need. The only problem is that CarTFT has software v1.0.0.2 (this is for configuring DCDC-USB) and this way all those functionalities can not be configured. On internet I found software v2.0 which also isn't last version, but at least I could configure DCDC-USB to work the way I need (by luck that functionality is enabled by default and didn't need to configure it :) ). Otherwise product is perfect and I am very happy with it.

Der Konverter wurde sehr schnell geschickt! Die Funktionen im Car Modus haben meine Erwartungen übertroffen! Hier hat jemand,der die Anforderungen im Auto genau kennt, ein hervorragendes Produkt entwickelt. CARTFT kann ich vorbehaltlos weiterempfehlen.

...ich habe lange im Web nach DC/DC-Konvertern für meine spezielle Anwendung gesucht und bin schließlich bei CarTFT fündig geworden, DC/DC-Wandler Typ DCDC-USB, In=6-36V/Out=5-24V, max.100Watt.
Das Problem war, einen DC/DC-Wandler mit einem weiten Eingangsspannungsbereich zu finden, der nicht nur ein paar Milliampere am Ausgang liefert und zudem noch eine einstellbare stabile Ausgangsspannung zur Verfügung stellt.
Alle diese Anforderungen erfüllt der DC/DC-USB von CarTFT!
Kurz zu meiner Anwendung: Ich habe in meinem Garten einen kleinen Windgenerator aufgebaut, der eine zur Windstärke proportionale Ausgangsspannung liefert, mit der dann 12V-Akkus aufgeladen werden. Da die Ausgangsspannung erst bei einer Windstärke von ca. 4-5 die "12V-Marke" überschreitet, findet bei Windstärken, die darunter liegen und die an meinem Standort am häufigsten auftreten, leider keine Ladung statt.
Mit dem DC/DC-USB von CarTFT kann jetzt bereits ab einer Spannung von 6V am Eingang und einer fest eingestellten Ausgangsspannung von 13,86V einen Ladung erfolgen.
Fazit: Im Vergleich Preis/Leistung sowie verfügbare Funktionalität steht für mich das o.g. Modul auf Platz 1.
