User questions & answers

Question:	Is this a 5:10 thread
Answer:	Kind of... if you twist them down all the way, water dribbles out from under the cap. Also, the twisty cap is removable. But it's a lot of water coming out, much more than my 1 gallon/minute flag emitters.
Question:	What capacity is the battery
Answer:	Yes, that will work just fine
Question:	is this a battery for 510 thread thc carts
Answer:	At end of your water tube, I screw emitter there. When it is an off shoot from line, use a T splice/joint allowing for several emitters on same line.
Question:	how do you work it
Answer:	I don't recall eactly but it was quite a bit because I have way more than I need. I'd say 10 -15 easy sorry I can't be more exact for you. They do work great I have them everywhere

User questions & answers

Question:	Can it be used for charging battery
Answer:	"Normal" polarity is INSIDE POSITIVE so the unit cannot short out to a conductor and cause a fire or power something it shouldn't. Any plug that has positive electricity on the outside is inherently dangerous.
Question:	Which side to i flip the switch to in order for it to work in the us (120v)? i'm confused about which side is 120v (left or right
Answer:	Not by any switch on the unit. However, one of the adapters has screw terminals, so you can connect in whatever polarity you need.
Question:	What are the physical dimensions of this unit
Answer:	Up to 36. (Watts=amerpage*voltage)
Question:	Hello, does this unit have enough power to plate large items such as a coyote skull ? in a 2 gallon bucket
Answer:	Variable in 100 mV increments

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:	Will this charge a 48V lithium iron phosphate
Answer:	No. The output is selectable to be 12 or 24 VDC.
Question:	i have 4 200ah agm batteries in parallel, what should i set the current control knob to
Answer:	Amps should not exceed 1/4 of the total battery pack amp hour rating so you should be able to use it at max power
Question:	Se le puede aplicar carga a un banco de baterias
Answer:	Yes. This can charge a 12 volt DC or 24 volt DC battery bank.
Question:	How many watts does this consume at 75 amps? Using a 2000 watt Honda generator as the power source
Answer:	What you won't find in the specs is this has power factor correction. I am getting the lowest of 0.94 which is very important when trying to run a converter off of a generator. Unlike regular switching pwoer supplies, that have a power factor of 0.72 and require 1300 watts for ~800 watts output, this does not. A 2000 watt generator will more than handle this charger at 100% (75 amps)
