User questions & answers

Question:	Will this work for a Samsung galaxy note
Answer:	No not fully charged., you will need to charge it for a full battery charge
Question:	Does this work on an iphone 6s
Answer:	I don't think so. I had another wall plug that I plug it into. But Mine didn't come with it's own.
Question:	Will it work with Samsung Galaxy S10e
Answer:	I use totally awesome. You can purchase it for $1 at Dollar Tree!!
Question:	Does this come with micro usb? Or I have to buy my own
Answer:	The cord to charge the Halo is the type that fits into the smaller connection next to the USB port. I don’t know what the other type is called. So that cord would then go from the Halo to your USB wall charger. The other charger that came with the Halo has USB on one end that plugs into Halo (it is the connection in the center) with the iPhone plug on the other end and I think that is called a lightning plug. Hope this helps.

Question:	Will this charge a Motorola android phone
Answer:	Hello Timothy, Thank you for your interest in the Strevis Running Belt. The size of the pocket is 4,3" wide and 8.2" long. However, if this calicase can be folded a little bit it might fit. The neoprene is flexible, but it can't be stretched very hard. We hope this helps you make your decision. Best regards, Hannah.

User questions & answers

Question:	engine start and one thee battery house set ...so i need a 5 bank charger
Answer:	Your description is not 100%, but it sounds like you need three Banks. One for each starting battery, and one for your group of house batteries, assuming they are all tied together.
Question:	I am installing this into my sailboat. What is the 110v amperage draw
Answer:	The power consumed by any electric unit is equal to the Operating voltage V times the current I. or Power = V*I in watts. If this charger is charging 2 batteries at 12 volts each and drawing 10 amps for each battery the power used is 12 * 10 = 120 watts each. So the ideal power used would be 240 watts for the two batteries. The AC source must supply power in the same way so you need 110 volts times I amps = 240 watts. Therefore the current, I, drawn would be 240/110 or around 2.2 amps , but you never have ideal energy exchanges because of heat loss and other things. So I would think you would need to have a source that could provide at least 5 amps @ 110 volts or around 600 watts at maximum usage. Much less current is needed for trickle charging.This gives you a margin of error of over 200% so should be OK. Hope this helps
Question:	I have a single starting battery (one bank) .Then I have two deep cycle batteries in parrallel (bank 2). Do I need a 2 or 3 bank charger
Answer:	you failed to give the the voltage, type, and size of batteries, and what they are being used for, but going with the information you submited. providing all of the batteries are 12v d.c. you require a 2 bank charger, but if i were you, i would order the 3 bank charger for future battery expansion, i would connect one of the charger outputs across the neg & positive terminal of the stand alone 12v dc battery, and i would then connect the second charger output lead across the 12 v dc neg & positive terminal of one of the 2 batteries which are tied in parallel. the charger in question permits the 3rd charger output to be connected to the 3rd neg & positive post of the 3 rd 12 v dc battery which is tied in parallel. but if i were you, i would first contact the manufacture reps, before you do anything, tell them your set up, and see what they think. in any event good luck, and above all do not forget to ware the proper safty equiptment prior to doing any work on any batteries.
Question:	Does this unit have a cooling fan? Does it overheat
Answer:	No fan. Yes it over heats. Mine died after a month and MFG service and support link, nor the registration lik work on their website. Unable to get through via phone. Had to buy a new one. I went with Charles Marine charger. Superb charger. Beware of this one.

User questions & answers

Question:	Is this compatible with a MacBook Air 11 inch model A
Answer:	do you mean model 1950?
Question:	Is it a battery and a charger
Answer:	If the package says it's for a Riccar Supra Lite Upright Vacuum ...it will fit. That's what I use. I would notuse any other kind meant for a different vacuum. You can try something else if you want... but I never have, so I really don't know.
Question:	Will it start charging on its own when I plug it in to something or do I have to press the button every time to turn it on
Answer:	Not sure, as I have an old Riccar Superlite upright vacuum.
Question:	Will this work for the macbook pro model a
Answer:	I am not sure, we got lucky, the bags we ordered fit, and don not remember our model.
