5V 1500mA charger w/Aura?

[petercreasey]

Is a wall charger adapter with 5V 1500mA output okay with the Kobo Aura HD?

Thanks!

A charger capable of outputting a higher current won't harm the device. The device will only draw as much current as it needs. A charger that's too small, has too little a current rating, could overheat. Whatever you do, don't use a charger that puts out a higher voltage!

T, Thanks for the good info!

Except I must ask, "higher voltage" than what?

Higher than 5 V (this is after all the standard USB voltage).

One of the standard USB voltages. USB Power Delivery aware chargers and devices also use 12V and 20V.

But yeah, 1.5A sounds like it's a USB Battery Charging spec charger and should work with all devices.

Uh, Endless... 5V was explicitly stated by the OP.

What I should have said is that as a general rule for any adapter as long as current rating for the adapter meets or exceeds the device's requirements you should be fine. You still need to be careful of making sure it supplies AC or DC as required, and that the correct voltage and polarity are observed.

Obviously, if it's rated 5vdc and has a USB type connector and follows that standard it should work for most devices. With USB even if the device can benefit from a higher current adapter it'll usually still work, but charge more slowly -though in some cases an adapter capable of only providing less current than the device draws, or can draw, may heat up. Check it periodically if unsure. Better safe than sorry and best to always use an adapter rated at least for the same current as the device -it only takes seconds to google a device's requirements if unmarked. It takes a lot longer to build a new home if an adapter is undersized, unfused as most are, and burns your home down -though odds are the adapter just burns out, depending on the design an internal voltage regulator could pop and ruin your device too, so be careful!

I was under the impression that the USB Power Delivery specification required using new cables to support the higher voltage/current to allow for capability detection for delivering over 5V/1.5A or bi-directional power capability At this time, I haven't seen any USB Power Delivery chargers and/or cables in the wild.

As TechniSol has pointed out the higher amperage will not harm your device as your device will only draw what it needs in power usage, meaning if it requires 500 ma that's all that it will draw. Now higher voltage is meaning more then 5v could destroy your device think of it this way, plugging an electric razor that requires 120 volts of AC to work into a system that delivers 240 volts AC will destroy the device. Now that being said, there are some Razors that are designed to work with 120/240 volts of power.
