How To Make Your Positive Grid Spark 40 Cordless With A Battery Mod and Joyo Wireless Transmitter 

Awesome. I hope it works out well for you!

Before you order those Joyo wireless dongles, I would order these ones. I'm about to do a review of them and they work better than the Joyo and they're the same price. amzn.to/4bgUcuU

Join the club, dumb-ass! ;) I also thought this had a battery! Just received mine. (going to sit in corner now)

Nice profile picture 😂

It works awesome. I have only used it for a few hours and it's still got a lot of juice left from the first charge.

I normally run for the hills on hyped up products…but, a battery powered Spark is tough to beat in the digital arena. I really didn’t expect it to sound as smooth and natural as it does. Saved me from grabbing a Pro Jr or Super Champ as my portable backup to my Deluxe Reverb.

Awesome! I just preordered the Spark Go today after holding off buying the mini for the past year.

@@Guitarnivore Great timing. I think that means you got it for 100. I bought one for my sister but its currently preordering for 129.

@@AlitaBeyay I got it a couple weeks ago. It's okay. Not very loud and you have to update the firmware and turn on Hi-Z mode if you run moderately high ouptut pickups, otherwise it's crackle and rattle on high volume.

@@Guitarnivore Thanks so much for the heads up. Its for my sister's birtday. but its being sent to me first. That will give me a chance to run the firmware update before I hand it off. I gave he a Lava me Carbon fiber Ukelele a year and a half ago. So she's not likely to overdrive it.💥 I don't want her to have to fuss with it before playing. So this was really helpful. I will have to look up HiZ mode now.

@@AlitaBeyay since it's an acoustic uke, you can put it in acoustic eq scenario. Might make it sound better. I can show you where to do that in this video. ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-mAByjOJo40U.html

I'm thinking about getting a Mini this summer. I love the 40, but this thing can be a bit much to lug around when I just want to take it to the deck.

@@Guitarnivore I have a Spark 40 also but being able to pick up the Mini and move is very easy. When I’m done I just hang up the guitar and stick the amp in the cabinet. Wish they had decent cheap wireless headphones.

@@TheFreeman4955 See. That's what I'm talking about! also have a my tablet synced up to my 40, so it would be nice to just have my phone synced to the mini, like two totally sperate setups. Damn, now I gotta figure out how I can afford the mini. 😁

I had my reservations as well, but mine has been good to me. I love this little monster!

Well my “first” Battery Pack is BAD, won’t take a charge 🤷🏻‍♂️ Going back to Amazon. Sadly it appears TalentCell’s QC program is to send all the units out and let the Bad ones come back 😞

@@joebentry Oh, that sucks and I'm sorry to hear that. That seems to be the sales QC model of a lot of Amazon sellers.☹

@@Guitarnivore - Update… 2nd Unit arrived quickly, but alas - Deader than a doorknob. 🤬. Is there some “secret” in using / charging this Battery Pack that I’m missing 🤷🏻‍♂️. This unit arrived with no Box or instructions - but was in it’s sealed “bags” 🙄 I took it out of the bag, hit the side button (just to see if it had any prior charge) and I see nothing lighting up, I plug in the the wall charger and nothing lights up but the LED on the charger. When I hit the side button (while supposedly charging) the status LED’s on the Pack all light. But as soon as I unplug the Wall Charger and hit the Side Button they ever so shortly light , then dim down. So once again I moved the Pack to the Garage for a 24 hour charge, come back the next day, and the same indicator sequence occurs 🤬 So is there some “secret” to making this work 🤷🏻‍♂️ Am I just an idiot 🤷🏻‍♂️ I think I’ll send it back and get a refund, I’m real concerned that even “If” I got a third Unit and it WORKED I’d be scared to actually use it fearing that it wouldn’t hold a charge at an event and or would stop working after it sat for a few moths 🤬 I’ve got other Battery Amps that have proven to do the job should I play where there is no power, I hoped this would have been a good option. 😞 Oh well, thanks for your Video, glad it’s working out for you 👍

@@joebentry did you charge it? I don't recall if I had to charge mine when I first got it.

The Spark 40 is pretty good about noise though with the ground AC adapter. I have a Boss Katana mini and if you use an ungrounded 9v power supply on that, y get all sorts of hum.

Thanks. That is a good idea. I just looped it and threw a small zip tie on it.

@@Guitarnivore That is also a great solution! Maybe even both at the same time would be cool.

Do it!. Those wireless dongles I used in the video aren't that great, so if you do decide to try some out, shop around a bit. I linked some much better ones in the pinned comment.

I prefer the 3m Dual Lock strips, where both sides are the same and they just interlock. Works much better and strnger than velcro and doesn't wear out like velcro. You can find that stuff just about anywhere.

How long? jk great vide dude

I prefer the dual lock strips to velcro. It holds much better.

I do have a great magnet for mounting but I am heeding your caution. I have also been considering different snap systems for mounting. But may go velcro.

Did you leave the battery on the Spark all the time or only when using the battery? Just getting info to decide which way to go.

@@peteryelverton2954 The black battery (which I put the magnets on) tended to discharge more if I left it plugged into the spark. It quickly got to where it would not fully charge after I installed the magnets. One thing to consider, the power checking indicator sometime would stay on if I didn't be sure to turn it off. The manufacturer has probably fixed this problem by now. The second time, I bought the white version of the talentcell. It works great! I don't notice any static drain. I didn't install the magnets in it.

I have done some research and I don't say this to negate your real world experience. But science suggests there may be a more likely different reason your battery lost half its capacity. Supposedly magnets can't harm a lithium battery. I still didn't use magnets because they are not strong enough to dependably keep this battery attached. at least not to a slick metal plate. Its possible a neodymium attached to a neodymium could do the trick.

I think for the price, you can find an amp with a power amp-in option to use as a powered speaker, while also being able to use it as an amp if you like. After the disappointment that was the Spark Go, personally, I would wait until after it's release and the real reviews start rolling in from buyers and not sponsored channels. The Spark 40 is fantastic in my opinion though.

I'm not sure. That's a bit above my electrical prowess. I certainly wouldn't try operating it in extreme temperatures for any amount of time that may cause it to malfunction.

I'm not sure. I've never tested it for the long run, but the battery lasts a long time. I think I'll give it a full charge and try to find out for you.

I'm not certain, but at least a couple hours.

As long as the voltage, mA and polarity is correct. It depends on the mAh's of the battery to determine how long it can run for.

I don't know approximately, but someone calculated 1 hour per every 2400mAhs, so maybe 6 hours, give or take?

The back of the amp says input 19V2.5A, which is 47.5W. The battery says 64.75Wh capacity. So 64.75/47.5 gives us 1.36 hours. But maybe if you don't use at max volume it doesn't draw that much power?

I've never tried playing at full volume. Now I must try and hope it doesn't damage the speakers. 😆I've got way more hours out of it than 1.36 on many occasions and that includes playing music though the bluetooth. I supposed that could be another factor in battery drainage.​

Good catch. I think the red light on the charger goes out once it's fully charged too.

About 5+ hours.

That's the first time I've seen that warning. They must have had some bad ones. At least they're aware and offering a replacement. You would think they would check the voltage before it left the factory.

since problems like this ( and the warning indicates such ) or often for a whole batch, I really hesitate to order another one. Do you know of an alternative? @@Guitarnivore

@@javatar1900 I understand that. Unfortunately, I don't know of an alternative at the moment.

The cable for the battery comes with it.

Yeah, that's a bummer. I don't understand why that is sometimes.

I'm not sure, but I've charged mine once since this video and I've used it quite a few times on and off and also used it for playing music. I would imagine more than a few hours of continuous play.

This battery is 17500 mAh at 2.5 amp consumption (what the power supply is rated it), it should last closer to 7 hours. SHOULD being that key word. I've used it for well over an hour and then on and off for quite some time before it ever required a charge.

@@Guitarnivore People that have the battery are claiming between 5.5 hours and 12. Either is probably more than enough for me.

@@AlitaBeyay yeah, mine lasts a good while. Rarely have to charge it.

You might have got a bad battery. It seems like it happens every now and then.

Roger that. Thanks. I figured it might be something that easy. But I didn’t know if I missed something or there was a step I skipped. Looks like I’ve gotta replace it. Thanks.

I'm sorry, I can't answer that question for certain. It'll last awhile under normal usage. There isn't a whole lot to this amp that draws a lot of power. They're hard to find right now as there seems to be a supply issue with this battery.

I don't think you can go wrong with most of the wireless rigs on Amazon. Enjoy!

I don't know exactly, but it lasts a while. I rarely have to charge it. There isn't a lot to these amps that draws a lot of power.

This particular battery has two outputs. The DC2 output is 19.5 volts.

@@Guitarnivore awesome! Thanks for the info!

It seems like it is in and out of stock quite a bit. I checked my amazon account and the same one I ordered is out of stock right now. You may have to wait until it's back. Sorry.

@@Guitarnivore yeah I noticed they're out of stock I was thinking about checking batteries Plus if they have something similar

I don't have the bag, so I don't know if it'll fit, but you can just take the battery off and put it in the pocket.

No. The THR10II is 15v, this is 19.

@@Guitarnivore appreciate the reply

Sorry, I've been extremely busy working on another set of videos, so it might be a little while. It lasts a good while though. I used it over the summer as a blue tooth speaker out by the pool. Like I said, I think I've only charged it two or three times since making this video.

@@Guitarnivore thanks. that's good enough for me.

@@schneidp20 thanks for understanding.

Still going strong!

Somewhere around 5 hours.

@@Guitarnivore how about charging time ?

@@lutfifirmansyah9443 I've never timed it, but I charged it on Saturday from a complete drain and it only took a couple hours.

Last

Despite what some folks on here have tried to calculate, it'll last for about 5 hours, and I may be undershooting it.

The last year or so it seems they;ve been having some issues with these.

It has USB 3.0 and my phone battery lasts all day anyway.

Its twenty more dollars which is not bad for USBC. I went for the 1701 which is white which matches my pearl spark. The 1701 white holds slightly more juice than its black counterpart but the manufacturer isn't really clear about how much more. I can adapt out for USBC but that was worth considering.

@@Guitarnivore The 1701 white doesn't boast USBC but maybe the new ones come with it. That would be a nice surprise when mine arrives in a few days.

It's probably not the adapter, it's probably the amp. Did you know that just about everything you plug in draws residual electricity when it's not on? en.wikipedia.org/wiki/Standby_power

@@GuitarnivoreThe amp turns off , it’s the green light on the adapter that only goes off when it’s unplugged from the wall.

@@dananthony6258 Ah, I see what you mean. I thought you were talking about the battery power cable adapter because that's what this video is about. The standby power thing still applies. Your laptop, computer, TV etc. are all doing the same thing when they're plugged in.

But if you already have the 40, why downgrade to something with less power for $229 when you can buy a battery for it for a fraction of the price?

@@Guitarnivore true. I am just worried about the consistancy of this powersource. If you ruin the 40 you will have to spend more afterall

@@jaixaphoto It's been 6 months. Still good.

@@jaixaphotowhy would it ruin the device? The amp will only draw the power needed.

@@riverrage Who says it will ruin the device? but it saves the hassle of doing this if you have the mini

A few of us have calculated some numbers based on voltage and capacity and we think it's around 5 or 6 hours.

These little amps are incredible!

The Joyos are sharp looking but even sharper is the Swiff, which use 900Mhz switchable frequency transmission, which is more reliable because its not competing with 2.4 and 5G. And it boasts 170 foot range for the same price. According to Scott Uhl who did 3 extensive comparisons of wireless guitar units this is his number one pick. The bright green glowing circle on the Swiff is super sexy looking. Scott says the Swiff is suitable for gigging.

Unfortunately. I'm not sure if it's a supply chain issue or what, but it seems to come and go every now and again.

YES! You can charge the Spark Foot Control too.

I know I'm asking a stupid question here, but you have no problem with the regular power adapter? If not, maybe you have the wrong cable from the battery to the amp?

@@Guitarnivore regular adapter works fine. I plug it into the DC2 out into the amp and it doesn't power on either. It works for the DC1 in but not out.

@@bradfuller84 Hmm. And you're just using the single cable with no adapters on it. The one with the yellow end going into the DC2 out and the other black end into the amp? DC1 in is only for charging the battery.

@@Guitarnivore yup. For some reason the DC1 port powers the amp but no sound. DC2 doesn't power on the amp at all. I have a cable that has two black ends that go into DC1 into the amp and that works. Just no sound.

You should have one with a yellow tip on the small end for DC2 and the other black end goes to the amp. I wonder if the cables you have are not what you're supposed to have. If DC1 is powering on the amp, it may not be providing enough power. It just might be backflowing just enough to power it, whereas DC2 is the 19v. I would try do a return/refund and getting a new set.

The Mini was released a couple months before I got the Spark and I wanted the bigger version. Well, this is a way to make your spark 40 have a rechargable battery too.

What? You think it only lasts one hour? I played for like 3.5 hours this past weekend and it still has about half left. Where did you get 1 hour from?

Yup. I've been kind of wanting the Spark mini for awhile, but now I'm stoked for the new Spark Go.

This was my first set two years ago and they were okay at first. I don't think they sound terrible, but their range is very bad. I updated the link in the description for a much better pair with a much better range.
