OFNA Supreme Power 12V/30A DC Power Supply
I bought this for my Hyperion EOS 0615i Duo3 Dual charger; I need to charge 2 x LiPo 7.4V/5000mAh at the same time (Syncro mode). This power supply delivers the 10 amps without sweating: that means it doesn't heat at all and the voltage drop is under 0.1V.

Btw: my charger has 180W x 2 power; This power supply will not provide higher voltage than 15V indeed, but I do not need more - and don't think I will ever do.

For me, this is the best buy I could find.)

researched for weeks on power supplies and pricing. everything from meanwell to power force and this ofna power supreme is the best bang for the buck hands down my charger just thanked me for finally giving me enough juice to tackle anything i throw at it. because this supply has the hard to find adjustable voltage i can charge my 9-10 cell nimh packs and "peak" them with ease. flux and e-revo owners will like the ability to charge 2 lipo packs with a big charger to. great job ofna)

And how this supply may be better than meanwell?
Meanwell S-350-15 costs 40-60$ has adjustable output voltage 12-18V and gives about 23Amps.
High power charges demand higher voltage supply because they are limited by input current. And 15 volt is not enough to supply 208B charger that it can deliver it`s 350W power)
