I have a 2012 Nexus 7 and the original charger got broken. I purchased a Belkin "MIXIT" 2.1A charger for it, and the thing was taking something like 10 hours to charge. When I use the 2A Chicony charger that came with another HP tablet, the Nexus 7 charges in a little over 3 hours (normal). When I charge the HP tablet with the Belkin charger, it charges quickly. So what am I to make of this? Why does the Nexus 7 charge so slowly on the Belkin charger. The same cable is being used.

I got one of those cheap in-line meters from gearbest. It says that the Nexus 7 on the Belkin charger never draws above 0.76A. Nexus 7 on HP charger: 2.6A. HP tablet on Belkin charger "3.89A". So I'm assuming that the meter is defective.

Simple answer: nothing is simple

Chargers negotiate with the target device over what voltage to use and how to charge.

Hence why manufacturers always recommend use the charger that came with the device.

The Belkin chargers are the biggest piece of junk ever made. They won't charge anything at anywhere near full speed.

If you want better charging you need a decent charger. My advice is an Anker.
