Just ordered this charger because of longer cord and 1.8 amp output. Was wondering anyone else try this charger?

The amperage is the maximum output of the charger available to a device or devices. If the nexus 4 only uses 1A to charge then it won't magically use more, just means that you'll be further away from the maximum ability of the charging device.

A lithium-ion battery is spec'd to have a certain number of charge/discharge cycles, based upon the charging current. Higher currents have the effect of reducing battery life. Having a weaker charger limits the current, and how fast the battery can charge, therefore extending the life of the battery at the expense of longer charging times.
For example, some of the Motorola phones come with 800mA chargers, but will consume up to 1.6A with an aftermarket charger. On the other hand, a Blackberry tour may only draw 1.1A. As JONNIE_R mentioned, having more power available won't result in greater currents utilized by the phone.
