Hi!
I own a Pegasus Astro Pocket Powerbox Micro and I can’t figure out how to connect my dew heaters to the correct ports — see the photos below.
Can anyone help me?

You need a dew heater 12V with a Male RCA plug - like this one: https://www.apm-tele...52cm-length-11w

 

Your plugs will not fit. My dealer said that there are no adapters ... I have to purchase a new dew heater. I did.

I have been searching the net for an adapter but have yet to find one.

 

Please share the manufacturer's name.  Never saw one with a barrel connector until now.

Order regular RCA male plugs from Amazon and solder them on to the correct length.  That is what I did and you have no hanging wires then they are all the correct length.

Make sure the heater straps are for 12 volts and not 5 volts.

It's really hard to tell what kind of connectors those are. IF the dew heaters are 12V, and if those are DC barrel connectors, something like this might work: https://agenaastro.c...or-dew-heaters/

Agena Astro has DEW Not heaters in different lengths.

It seems strange that there are no adapters. You should be able to fashion some yourself by connecting these:

To these:

Only tool you'd need is a screwdriver.

I'm not sure why they decided to use RCA in the first place. It's NOT a power connector. I guess it was low current enough not to worry about, but still. Maybe someone out there knows the reasoning.

Until the  (shudder) 5 volt  USB heaters came out, every heater I've ever seen had an RCA connector.   Back in the day I used a variable PWM driver board and built a heater controller with RCA output ports.

 

When I got my first Air Plus I took some of my old Dew Nots, cut the RCA plugs off and soldered on right angle Male 5.5mm x 2.1mm plugs.  The coolest part is I cut the cables to length which cleaned up the cable management.  I have 3 rigs setup that way...

I'm going to do this.

I thought about using connectors like that, but then again a solder connection is always better than form of screw/clamp connection.

 

Another issue is the individual wire strands are not supported/restrained which exposes them to bending and eventual failure.

 

Easy is not always better...

Gaiden, I have a much more simple solution, and more local to you being in France.

 

I'm assuming your dew heaters are SVBony and come with the optional 3-level power switch?  If so then the connection from the dew heater side is female 5.5 x 2.1mm.

 

You just need one or more of these from First Light Optics.  I used the same on my rig.

Two things:
I agree that solder is better, and if it were me, I'd actually suggest using the combination low-temp solder + heatshrink tubes you just hit with a hot air gun, since they also have some waterproofing.
On the other hand:
1) I didn't want to assume what tools they have or what their comfort level is with things like soldering. The option I gave is both easy AND requires no additional tools beyond a common screwdriver.
2) Since this seemed to me to be a bit of an experiment, this seemed like a good way to see if things worked before coming up with a more permanent solution.

Easy isn't always better, but that doesn't mean it's always worse! 😉

Edit:
Re archiebald's post: I THOUGHT it was crazy that nobody had one of these ready-made!!
