Hey Lifehacker, Can I use any Qi wireless charger with my Nexus 5 and Nexus 7, or are there specific specifications (such as voltage and amperage) I need to match? Thanks, Wireless Wannabe
The Nexus 5 and Nexus 7 use the Qi interface standard which allows them to be charged via electromagnetic induction. They should be compatible with any QI/wireless charging pad designed for phones or tablets. For added peace of mind, most manufacturers will list the specific models that are compatible with their charger, so just take a gander at the specifications list if you're uncertain.
You can snap up Qi charging pads for under $20, although as with any hardware accessory it usually isn't advisable to buy the cheapest no-name brand you can find. Another thing to keep in mind is that not all chargers are physically suited to all phones -- it could be too small or oddly shaped, which could affect charging performance if your phone isn't flush against the transmitter.
If you can justify spending $50 on a phone charger, you may want to pick up Google's official Nexus Wireless Charger. In addition to charging your Qi-compatible devices, the pad also comes with inbuilt magnets that helps to keep the Nexus 5 and Nexus 7 secure and thus ensure a faster charge.
Otherwise, plump for a device with a flat, rectangular footprint and you should be fine.
