Is the motor marked in the blue case like the black case?
No..no markings on the blue case
You'll need to open the case to see if a voltage is printed on the motor, or if that diode mentioned earlier is present.

Re: portable air compressors for tires

... The small Ryobi was only $19.95 at Home Depot, and is very ergonomic, shaped like a drill. They have a larger one as well, too large. But it requires their 18V lithium tool battery. It is much smaller than many others, though it is not as small as it could be, internally they are all pretty muc...

Re: portable air compressors for tires

I'd be interested to know about the motor inside the unit- if it is marked as 12V or 48V? Mine has no additional circuitry inside- the 12V cigarette lighter is connected directly to the motor.

Re: portable air compressors for tires

OK, just been offered a refund from banggood, I guess it's an admittance that it's a 12V item. I think it will go to my brother as an emergency option for his car (but I AM tempted to put 48V through it ....) So back to the original hunt for a cheap emergency compressor... I have to say that I'm rea...

Re: portable air compressors for tires

I've just come across one that takes AA batteries . More expensive but you can get those batteries most places (apart from on the trail!) but I guess rechargeables would be good, NiMH possibly better than alkaline. I'm not so sure about the AA size, possibly a bit small, so it's one of those reviews...

Re: portable air compressors for tires

if anyone is interested there's a 48 - 60V portable compressor at banggood- 8.44 UK pounds delivered so that must be under $12. There's only a few left so if you're interested move fast. (I've looked at banggood a few times but not previously bought from them).

https://www.ebay.com/i/253237165814?chn=ps This is the one I'm in love with. NOT cheap, but at the black Friday sale it can be. Useless of course, if you don't already have the Ryobi drill, and have the battery and charger. A bit bulky to carry, but when you know you are heading out with a leaker, ...

portable air compressors for tires

There are lots of cheap portable 12V portable compressors for lowing up tires, and there are even a few for 48V - 60V. What's the difference that makes them suitable for the higher voltage- is it just a series resistor? Reason is I generally run at 36V so would like to convert a 12V to run on a 36V ...

Re: Show Us Your Homemade Battery Housing

More good ideas. I love the diversity of things that people come up with. My batteries go at the back because my bike has a step-through frame and I can't put anything in that space- I need it to get onto my bike because I can't lift my legs high enough to get over a crossbar. As time has gone on I ...

The problem is that these are not mass production items- you'd need something that is mass produced then you lose the nice things such as that programmable settings can be customised to your individual desires. You can get lower priced controllers closer to your vision but you get what they make and...

Re: EMC-2000 charger from ecity (1500 to 2000W)

Do you have an electrical tester? You really need one to to sort this kind of thing out, an inexpensive one is all you need. simple checks first, faults can often be simple and hopefully yours is. unplug the charger. Try simple continuity First check the positive battery wire - check from the pin on...

Yeah, I'd be interested too- a quality one would be good- and as said Crystalyte can't supply them. I'd like one that's longer than standard too- an extra 10 - 20mm thread length would be nice. When researching sites I came across one that said the front and rear axles were the same but I'd always t...

Re: Crystalyte X5 axle, who wants one?

The threads on my front are also poor- the major diameter on mine is smaller than the standards specs on both sides, with one side worse than the other. I tried Crystalyte but they couldn't supply them, they'd probably have been poor anyway. In the end I used nyloc nuts - there seemed to be 2 differ...
