Helder's Game Tech GBA Power Cleaner

After installing it, i still hear the buzzing sound. I thought it would do a better job at cleaning the sound I haven’t really noticed any difference.

Significantly reduced the unwanted noises created by adding a modern backlit LCD

Great item and easy to install.

I've used a few of Helders power cleaners and they work as advertised. Highly recommend.

I soldered this to my board and checked each solder under a microscope to make sure I didn’t bridge anything. It cleaned up my sound with my rechargeable battery installed. I’m happy.

Good product and reliable people . Thank you

If you want to buy this because every Youtuber installs it in their mods, this review is for you:
That's what I did, I got this because of YouTubers and it seems easy to install when they do it, but after actually seeing what needs to be done this is a very advanced solder job that can seriously mess up your GBA beyond repair if you screw it up.
I talked to the modding community on Discord and they all told me to not install this and that people screwing up this installation is a frequent problem in the community.
They asked me "Why are you installing this?" To which I told them I saw it on YouTube as a MUST buy and i've been told it helps to clean up the power.
The community there sees this as shady advertisement. That there is no need to "clean" the power unless you really see a need for this.

Their advice is to first start modding your GBA and if you have any issues, ask someone if this would help alleviate your issue. Don't buy this or attempt to install it unless you know what you're doing and are sure this is what you need.

I didn’t have much hiss through my speaker except at very loud volumes, which I didn’t often use. This cleaned that up and now it sounds great even at loud settings. I am not running a sound amp, just an IPS screen with lipo battery and a flash cart. Mileage may vary depending on how modded your board is but this worked great for me

very good. flex board. make sure your tip is clean or other wise it will remove a capacitor by accident. but a good mod

I love to buy in Retro modding, it's fast, cheap and have all the accessories for my GBA. The cleaner is just what I need

In conjunction with the Cap kit, Audio amp the audio is load and extremely clear. Giving 4 stars because either the amp kit or the power cleaner causes the audio to turn off at about 15% of the volume. Wish the shut off threshold was just a little bit lower.

This is a simple mod to install (though FYI solder points are small) and helpful if you're getting staticky background noise through your speaker, particularly with extra upgrades like the IPS screen. It's not a cure all, if your board's got bigger issues you may need more work like a new speaker, power switch clean or replacement, or new capacitors, but if you've got an otherwise clean and functioning console this does a great job filtering sound and improving power efficiency.

Tricky install. The capacitors you attach to are tiny. Need a steady hand.

Great product!! Exactly what I wanted!!

Nice addition to a gba. Makes the sound from the single speaker more clear and crisp.

If you have an IPS modded GBA and notice noisy audio from the headphone jack, get this. If you are comfortable opening a GBA the soldering is pretty beginner friendly.

Very easy to apply to gba, and helped reduce humming that might happen when adding the ips screen.

Helder's Game Tech GBA Power Cleaner

This power cleaner cuts down on the noise the GBA generates with an IPS screen installed. Compared to an unmodified GBA this improves the sound and almost completely eliminates the background hum that is prominent when using headphones. Easy to install if you have some soldering experience.

I have this installed as well as the dehum/dehiss kit from RetroSix and even with both of these I still have some humming when my volume is turned all the way down. I have a V3 2in1 IPS screen (from Handheld Legend), Helder's FlexAmp, and an EZ Flash Omega and at this point I'm not sure if there's anything I can do to fix the hum/hiss. Not sure how to feel about this part as it might do something, but it definitely does not fix the problem entirely (at least not for me). On the bright side it was easy to install IMO, with the solder parts being large enough to easily make contact with the capacitors.

Super easy to solder on and does a remarkable job at limiting noise on the motherboard of a GBA.

Buy this if you are going to mod your gameboy in any way.

I didn't really have any power issues with my gba but I ordered the amp as well so I figured it couldn't hurt to install the power cleaner. The install wasn't too difficult but I'm not sure I noticed a difference.

Very easy and clean install.

It’s a night and day difference in audio a must imo
