User questions & answers

Question:	Is there any manufacturer warranty for this product
Answer:	Yes, It can. I use it to charge my e-bike's 10s5p battery pack (that is 10 in series, and 5 in parallel (50 batteries)). It works wonderfully.
Question:	Hi I cannot see the switch for 200v at the back. Are you sure it exists
Answer:	There's a switch in the back of theunit marked 110v /220v , slide the switchto the right for 110v and to the left for220v, you can use your finger nail to do it.Hope this helps.
Question:	Does it work with 230V In the description it says yes, but in some questions it says no
Answer:	The unit I received is 11" x 5" x 6" without the power cord installed.
Question:	Dimensions given dont seem to match pictures of the case. Actual height
Answer:	For copper plating the formula is ~0.07-0.2A per 1 square inch of the surface, though in most cases you'd use about 0.1A per sq inch. That means with the supply that provides up to 5A you'd be able to work with up to 50 square inches of the surface. I imagine a coyote skull must be more than that even if you only plate the outer surface of it. I'd say 5A should be enough to plate a skull of cat (outer and inner sides) without having to struggle with the base layer (that's done at higher current settings) not being tough enough. For a skull size of coyote's you'd probably need a 10A power supply. Hope that would help others who might have similar question

User questions & answers

Question:	I'm thinking that this is what i need to step down the 18v 39w dc power coming from my solar panel and plug into my 12vdc 3.0 amp battery charger
Answer:	It is a small screw adjuster. Mine stays constant.
Question:	Can I use this to reduce my 48 volts batterys to 12 volts golf cart lights
Answer:	Mine has stayed constant. I went down from 18v to 6v.
Question:	Will this work to convert a pulsed dc input (about 5-10 pulses per second) to a constant dc output
Answer:	I believe so. It has a tiny adjustment screw. I used a volt meter as l had to go from 18v battery down to 6v.
Question:	How hot does it get
Answer:	Turn the screw on the bottom (pictured). Of course you need a voltage meter. For standard 5V you can probably find a pre-set version.

Question:	Can this be used as a battery maintainer to program automotive computers
Answer:	I have no idea im assuming its to have someone come and assemble it for you but $140 is insane you can easily put it together yourself.
Question:	How do you adjust the voltage and amperage
Answer:	The front has the “holes” that will attach to a headboard. I’m not sure about being able to add another pair of ends.
Question:	Is this 25 amp at each input for a total of 50 amp, or can one device draw up to 50 amp from one input
Answer:	Only about a foot, and I bought the frame to use with a full sized mattress and the middle piece doesn't fit, so check it immediately upon arrival to make sure they sent you the correct pieces...
