The two side Universal Ports are Defective
on November 26, 2013
I received this unit as a review sample. I've reviewed Bolse products before and found them to be very high quality. The first thing I do with any usb charger I get it hook up a variety of devices and test them with a usb current meter. The high power usb compatibility and output varies widely and without an electric meter to perform actual measurements it's hard to know if you are trickle charging or getting full power.
With this model the two iPad/U ports work well with Apple products like you'd expect. The Samsung/U port works well with Samsung and ASUS smartphones and tables, putting out just over 1W.
The reason I'm docking it 3 stars is because the two side ports labeled Universal(U) are terrible. The label on the device says they should be 1A ports. I measured around 0.444A with every single device I tried. For those not familiar with USB 0.5A is the max that a standard USB 2.0 port will put out, and many devices will draw just under that. It seems to me that in this case they didn't wire up the data pins on these side ports correctly, resulting in all devices failing to sense that they could draw up to 1A and then falling back to the save 0.5A max. I'm not sure if this is a design flaw with every unit of this model type or if it is a manufacturing defect with my particular unit. Either way, it's not acceptable.
