BESTEK 150W Power Inverter with Dual USB Charging Ports

I have tested this device on various 12V battery packs that I have laying around in my office. I specifically purchased it for a small application to make some of my electronics projects more portable to move quickly to other places in the workshop. This device has helped charge varioius macbook pros, run small 12V .03A fans for hours on a 12.6V custom 18650 battery pack with 1A output and the inverter powers the whole things flawlessly. I even tested the over protection circuit with a small saw and it cut the power and protected the device before blowing up the battery pack.Yes the fan is always going to run, you should know that. It's a inverter meaning that it's taking a smaller powered battery and stepping up the power which guess what generates heat folks! The more power your draw, the louder the fan. Why?! Because it would otherwise be a fire hazard and overheat. A possible solution would be add a heat sink but that would make the device bigger and still require a fan. Stop leaving bad reviews for fan noise, that that is a side effect of using an inverter.This device does exactly what it says and works very well. I have tested all outputs at once and it still works and doesn't trip the over power protection. Of course though, I plug in devices that match the specs. Don't always believe what you see on the back of each device, use it as a guideline. You need to take a percentage of that value and accommodate for variance in device draw under load. If you over power the device, that is on you, not the device.

It works well, but the fan is kinda loud.

Este convertidor de corriente para el carro cumple bien su función y resulta muy práctico para viajes o trayectos largos. Me gustó que permite conectar varios dispositivos sin complicaciones y entrega una carga estable, sin cortes ni sobrecalentamientos molestos. Además, su tamaño compacto facilita colocarlo en el vehículo sin ocupar demasiado espacio.Es una buena opción para quienes necesitan usar aparatos pequeños o cargar equipos mientras están en ruta. La instalación es sencilla y el funcionamiento es bastante silencioso, lo que da confianza al usarlo con frecuencia. También se agradece que tenga protecciones básicas para evitar problemas con la batería o los dispositivos conectados.En general, es un accesorio útil y bien resuelto: no llama la atención por ser sofisticado, pero sí por cumplir de manera confiable con lo que promete. Para quienes buscan una solución práctica para tener corriente extra en el carro, puede ser una compra acertada.

Excellent.

If you have rechargeable battery operated tools and drive to where there is no power to work you need this.

Muy bueno

Going to use it this week for work

Fit a bit tight in the lighter, as expected. Left my charger in a hotel room, and it took a while to charge my phone. Actually bought it to charge my portable charger.

Works very well!

Great purchase. Works great. We used it for an inflatable 4th July rocket for front of truck and it worked a great. My husband didn’t know they made those so he was very happy

I haven’t used the inverter for powering any AC devices, but it powers up my phone just fine. My only issue is that my 12V receptacle is inside my front console, and the unit takes up more space than I had hoped. It also does make noise while plugged in. Otherwise I’d give it 5 stars.

A+ Car Phone Charger and I would buy it again.

Works great in the car if I need to charge my phone and computer.

Thing still works unlike most junk I buy these days

it has a safety feature where if it's trying to pull too much power it will shut off

Muy puntual

My 2 cars

Works great

Haven’t used it yet but I know it works because it makes a noise when I start up my car, I like how many outlets it has different options very convenient.

This is a really good charger for on the go for charging anything that you can’t charge in the vehicle. I really think it’s a good idea to use this for road trips or if you’re a driver.

Just as seen pictures. Works great!

Very simple to use.

Great deal, awesome price and fast delivery!! Works great!!

It works for my call.Marco I can plug in multiple devices.Anytime I want to

This is a small and compact package that is unobtrusive.

This was a gift for my boyfriend. He's able to plug his car vacuum in, and charge it, so that is always ready.

Love it works wonders with all three kids

Unit works well without taking up a lot of space

Like it, it’s small and fits perfectly on my truck

I love it! Perfect for travel

This inverted is just what I needed for a car show to decorate my car with lites.

Very useful item for travel. My car doesn't have an inverter outlet so this is perfect!
