I got mine in a bundled set w/ the mfj-971 and mfj-9020 (all of which i'm pleased w/ so far). Even before receiving this unit, I found it odd that it only supplies 1.2A. Thats barely enough to even supply the QRP rigs that its designed for! The solder job on the underside of the board was shoddy at best. There were some component leads that were barely soldered at all. I guess the fortunate thing about this unit is, the case is nice and there is plenty of room to add mods. I was fortunate enough to accidently blow out the 17vac wall-wart that powers it, cuz this gave me the oportunity to rework some of the components and get the power up to a useable output. I also took out the nicad packs and put in a SLA battery from allelectronics.com. The SLA battery is an ABSOLUTE perfect fit. In all, I absolutely would NOT recommend this product.

The unit is too high priced, too low a quality and too little available current on AC for it's task. At $69.95 WITHOUT battteries, it is a very highly priced supply. The unit comes without nicads (plan on spending another $50.00 + to get 12 nicads @ 1.6 Ah, more for the 4 Ah biggies. ) and isn't even designed to hold the lightest 1.6 Ah's. The batteries just fall out of the holders when you try to reassemble the unit! Forget the 4Ah's. You would have to glue the batts in the holders with silicone. One of the battery holders split by the contacts due to the cheap plastic used. They just cant stand the strain. The MFJ-94xx SSB series of radios ( which are quite good!) that the MFJ-4114 is sold to work with requires 2.2A @ 13.8V on voice peaks. This unit can only supply 1A on AC from it's LM7812 regulator IC. Not 1.2A MFJ rates it for. Last I looked the LM7812 is rated at 1A. You could build much better, cheaper with batteries than MFJ gets $$$ for this without. Look for a Vector portable battery. Total waste of time.
