LAOMAO DC-DC Step-up Boost Power Supply Module Adjustable Power Apply 3V-32V to 5V-35V XL6009 400KHz 4A Max

Easy to use converted my fishing headlamp 6volt battery pack to use 12volt leds lights. Battery now last 60 hrs not 6

Very simple to use dc in and dc out controllable via adjuster. Measurements made on 'scope showed very little ripple or noise, not used it with audio so don't know if it would effect sound. Works with temperature sensors and micro PC

Product worked as intended, however the component holding the screw to regulate the voltage was not soldered properly on the board and was bend. I assume that that part would have broken off if not fixed. I easily fixed it by reflowing it and pressing on it.

You'll need to replace the diode and add some ceramic caps... and the stated specs do not add up to the XL6009 specs.Unless you want loads of ripple and heat...

I found it a little greedy on current at low input voltage for minor loads. But that's the efficiency trade off right there. Moderate loads should be just fine. Weak point may well be the electrolytic capacitors in hot environments. Regulation of output voltage is poor to non existant.

Used this to provide a +12 voltage as a Mosfet gate driver in a MPPT solar controller circuit design. Worked perfectly and easy to adjust as needed. Very happy with it.

Does job

Tried this boost converter board for a USB to 12V source. The USB source is limited to 1.5A, and the output demand was 5W. In this case, the load is attached to the converter when it is starting. The converter has a very high inrush, collapses the USB supply into constant current, and gets "stuck". This may be OK for higher input voltages or very low output currents- just mind the large inrush current. Note the 3V minimum input does not agree with the XL6009 datasheet for a 5V minimum input.Found on my power supply I'd need a 2.5A current capability for this converter to start in these conditions which won't work in my project.

voltage is same as input always even after rotating the Variable resistance a lot.

Ho acquistato questo DC-DC converter step up, per elevare la tensione di uscita fornita dal power bank di 5,2V. Ne ho trovati diversi su Amazon, ma questo mi ha colpito perchè era in grado di erogare 3A continui, con un picco massimo di 4A, cosa alquanto difficile per questo genere di prodotti (soprattutto se poi si guardano le reali dimensioni del prodotto), che normalmente arrivano a fatica a 1A. Comunque, l'ho testato con attrezzatura professionale, e devo dire che sono rimasto sbalordito dalle prestazioni. Non solo tiene tranquillamente i 3A continui, ma addirittura arriva a 3,6A (sempre continui), ma come anche consigliato dal produttore, quando la corrente erogata dovesse raggiungere valori importanti come questi, è preferire dotare l'oggetto di una adeguata aletta in alluminio per dissipare il calore ( e magari anche una ventolina, aggiungo io). Ne ho presi due, uno lo devo settare sui 12,6V con 0,6A continui di assorbimento, e il converter, dopo averlo testato per circa un ora e mezza, non era nemmeno tiepido, praticamente freddo. L'altro converter l'ho settato sui 12,9V, e con circa 1,5A di assorbimento continui (sempre dopo circa un'ora e mezza di test) era appena appena tiepido. Direi quindi prodotto promosso a pieni voti.

Fait le travail correctement

Good product works fine but after some time the volt control knob was not working other wise best product

Funktioniert für Spannungssprünge von 6V auf 12V, habe damit meine Fahrradlampe am E-Bike angeschlossen.
