Jetstream JTPS28 12V / 28 Amp Power Supply is small with no sacrifice in features or power the Jetstream JTPS28 provides both high current (28 amp surge) with a low profile and light weight. I specifically liked it because it is a small footprint and affordable I bought it new at a ham fest. Now my power supply can actually become part of my console and take up less space on my work bench.
