AC Adapter Compatibility for Inspiron 1545 Laptop

The AC adapter for my Inspiron 1545 went bad, and I'm waiting for a replacement to arrive by mail.

However, I have to fly on business tomorrow morning and must use the laptop on my trip.  I

have an AC adapter for a Dell Latitude X300 which appears to be plug compatible with my Inspriron.

The specs of the adapter are a little different, though.

My Inspiron 1545 adapter (the bad one) delivers 19.5 V and 3.34 A.  (PA-21family).

The Latitude X300 adapter, which I would like to use, delivers 19.5 V and 4.62 A. (PA-10 family)

My question:  can I safely use this X300 adapter with my Insprion 1545, and expect it to

supply the proper power?

Thanks.
