Step-up transformers 12V to 24V

[rwaldrop13]

Good afternoon. I was wondering if anyone has used step-up transformers to change voltage for specific uses. In this case, it's to provide higher amps/voltage to maintain charge levels for iPads used for navigation. My boat was a 24-volt boat and I had to use a step-down transformer to replace a damaged anchor light, but wanted to know if anyone has reversed the process. I was actually plugged into 110/120 for my tablet on the boat, but this came up with a friend's boat and he doesn't have a 110 outlet close to his helm station. There's plenty of these devices available - Just search Amazon! But I want to know if anyone has practical experience with them. Prior to boat life as a service manager, we installed one in a golf cart for a customer but I left that job before ever getting any feedback.

I'm powering a 24volt Simrad 10kw radar from 12volt supply on our center console with no issues.
This is what we used. Newmar 12-24-25 Step Up Dc-Dc Converter 25 Amp Continuous

Victron also makes them. My stabilizers are 24 volt and I used a Victron unit.

Found this and others on Amazon

Thanks Seven and everyone else. Definitely some good feedback here, I appreciate it. The Amazon listings are familiar, since i used one to step down 24v to 12v for my anchor light. Since we're stepping up, I wasn't as sure of the performance.

I wasn't confident enough with the Amazon units for a radar which is why i spent the extra money for a Newmar.
Do have some of the Amazon types that are used for some light fixtures which have been fine.

Please keep in mind a few things;

Voltage increases require more source amps to draw. That supply 12V fuse or breaker may have to supply a few more amps.

Check your required Volt-Amp requirements and ensure the selected DCv to DCv converter can deliver what is required.

For an I-Pad, probably not an issue. For a radar array, could be critical.
