I just picked up the PowerFlow-50 for our King Air 350 a couple weeks ago. Works great for doing the database updates. Compact, lightweight, and has a digital readout that shows both output voltage and amperage draw. Works well with both the PL21 and Fusion systems, as I have used it on both. Shipping was fast and I thought pricing was good for such a compact and light power supply. Great product VDC! Highly recommend!
The experience - purchase, delivery time and cost have been as good as it gets. The power unit itself is amazing and wonder why I did not purchase sooner. Previous experience with older units allowed me to really appreciate this unit. Light weight, yet powerful.
The Lear 45 toilet flush motor of all things will not operate on ships batteries!
This little unit saved the day when repairing and testing the flush circuit.
The volt/amp meter is a real plus- I can see in real time as the batteries are taking a top-charge.
As a bonus I can use it on the 28v Baron & Bonanza and see the amps the gear motors are pulling.
