Useless Automotive Charging Converter

This product is a complete waste of time! I tried using this charging converter in my garage, and it didn't work at all. The only good thing about it is that it's compact and easy to store. However, the cons far outweigh the pros, as it simply couldn't handle the power required for automotive charging. Don't waste your money on this product!

Pros
  • Efficient charging of devices
Cons
  • Produces high heat when charging

False advertising. 0.95A outputs only

According to my USB power meter they only output 0.95A so they are incorrectly advertised as 2A output when they are not.

Pros
  • Power supply accessory
Cons
  • Communication with seller

So few reviews. for power converter

A long time ago I bought a drox version 2A, but for the same price I got two DZS electric 2A boards now. I used it to replace an old worn out gorse in a DIY Altoids power supply. It works well although the indicator turns red when under load, maybe my batteries are dead, another reviewer said they only put out 1 amp. 2A at 5 volts is 10W, if your power supply can't deliver 10W you won't get a 2A charge capacity. In my case my phone draws more current at lower charges and less at battery…

Pros
  • power converter
Cons
  • slightly dented
