Just got a Nilkin Magic Disk qi charger (5V/1A output).
The charging speed is 50 mins for 10% (chargered from 90% to 100%) on the Nexus 5 with Ringke Fusion case on.
Seeing similar speed on my N7 2013 as well.

There are a few things that affect this, and bland.life if you could be more specific.
5V/1A output is important, but how are you powering your charger? Are you just using a USB connection to a computer? If so, is it USB 2.0 or 3.0? Both of them do not supply enough current to fully power your Qi charger. USB 3.0 is better, but still not good enough. Either of these will result in a slower charge speed (if you plugged your phone directly into a USB port on your computer to charge, it would also charge slower than using the wall adapter).
Or are you using a USB wall adapter? If so, does it supply enough amps to the charger? Your charger has a 5V/2A Input current. Are you using a 5V/2A Output USB wall adapter to power it? If you are using anything lower, again, your charger is not being fully powered and your charging speed will be slower.
Wireless charging will always be slower than wired. It's the convenience of wireless charging that is the selling point. A fully powered 5V/1A Qi charger will charge the Nexus 5 around ~70-75% the speed of wall charging with a wire. The Nexus 5 takes ~2 hours (give or take a few minutes) to charge from 0 - 100% on the stock adapter. Expect wireless to be ~2.5 hours (give or take a few minutes).
You need to understand how these batteries charge. There are different charging speeds at different times in the charging cycle. The very beginning and end of a charge cycle are slower. This is to protect the phone and battery. This also will happen both using wireless Qi charging, or standard wired charging.
You chose to record charging time using 90 - 100%, this is when all phones will be charging at their slowest. Think of it maybe in terms of the cooldown period after someone has finished running a race. You don't wake up, run a race full tilt until it's over, then directly lay down and sleep. You will probably hurt yourself. Even when growing up, you learned to stretch and warm up first, then push hard, then walk it off to slow your heart rate gradually. The same concept applies here with charging. You decided to watch when the race was over and everyone was walking around. Haha.
If you want to gauge how fast it is charging, look at the total time to charge.
