Video Transcript for Performance Tool Solar Battery Charger Review

Speaker 1: Today you'll be having a look at and being shown how to install Performance Tool 2 1/2 watt solar battery charger, part number PTW2997. Here we are at our utility trailer. Here's what our solar battery maintainer looks like installed. This solar battery maintainer has an amorphous solar panel built into it and what that means is it'll help maintain your battery charge even on a cloudy day.As you can see, we have a little blue LED light right here and when it's flashing that's indicating that your battery is being charged. Now one of the reasons you're going to want a system like this is if you have a trailer or any vehicle that has a battery in it that sits for an extended period of time, especially if it sits outside, you'll want to make sure the battery is maintained so when you go to use your equipment or your vehicle or your trailer again, the battery still has a charge so you can use it properly.This maintainer here with its 2 1/2 watt power output will ensure that your battery is maintained and has a slow charge run to it at all times during daylight so your battery will maintain its charge and won't be run down on you when you need it again.What's great about this maintainer compared to other solutions on the market is that this is a very affordable option. Some battery maintainers that are solar panels like this one can cost you several hundred dollars.

This one, however, does not.When comparing the solar battery charger to a traditional battery maintainer such as the CTEK universal battery charger with pulse maintenance, part number CTEK56865 the solar maintainer has the ability to maintain a battery without having a traditional charger plugged in to a 110 volt outlet such as the CTEK universal battery charger which doesn't have the ability to maintain your batteries via solar power. You have to have it plugged into a traditional house outlet.Another great thing about this unit, besides the fact that it can be portable and you can mount it inside a windshield on a vehicle or charge batteries with the clamps, is that we have a very long cord length. Our adapter cords have a total cord length of about one foot from the end of your connector here to start of your adapter here. And then the cord off of the panel itself is a total length of 8 feet, so you have 9 feet of total length in order to reach your battery or your vehicle where you need to plug it into.This is what our charger and maintainer comes with. We have our solar grid here, this'll produce our charging output.

It'll be outputted through this connector here. Now with this connector we have a multitude of options where we can connect to in order to charge and maintain our batteries. Here me have the opposing end of that connector, this will give us alligator clamps to hook directly up to a battery to charge it.Now if we have a vehicle that is sitting outside and sits for a while and doesn't get driven, we have an adaptor here which you can plug into your power outlet or your cigarette lighter, or your accessory outlet, and this will charge the vehicle's battery from inside. You don't have to worry about having any wires running underneath the hood and you can do that with these suction cup mounts here. These will clip on to your panel so you can stick it inside your windshield and have it plug into your power outlet or cigarette lighter.So if you don't need to have this mounted inside your windshield on your vehicle if you're using it for a boat trailer or utility trailer or an RV, that can be done as well and this can still reside outside.So here we are with our utility trailer, as you can see here we have a winch which is powered by a battery inside this battery box.

Now this battery doesn't have a way to be charged or maintained, so we're going to correct that with our battery maintainer. First thing we need to do is find a place to mount our solar array.Right here on top of our toolbox, perfect place for it. Now we have it on our top of our toolbox here, it's not going to interfere with our winch or anything when we open the toolbox lid. We've already verified that. Your particular application may vary.

So we'll put some pressure down on it, take a drill, go through the hole, make a mark, do the same on the other side. With marks made I can get the panel out of the way so it doesn't get damaged and I'll just continue drilling the holes until they're all the way through the top of the box.Now we'll attach it with our holes drilled, we've set the grid back on top of it, we have some Fender washers and some bolts. You have to supply your own. So we'll go through the hole. We're using Fender washers because it'll help disperse the force so we don't have to worry about cracking the plastic around the grid.We'll open our box up. On the underside we'll attach a lock washer and a nut. And now we'll tie down our hardware using a ratchet and a wrench. Okay now we need to get access to our battery inside of our battery box to make our connection. Now we can attach to our battery using our alligator clamps. The black will go to negative, the red will go to positive. However, in our case our customer wants to have this permanently attached to his battery, but still wants to be able to charge an auxiliary battery for his equipment on his trailer. So we're not going to use the alligator clamp, instead we'll take our power outlet adapter that you would use if you're charging the battery in your vehicle where you solar panel was mounted on the inside of the windshield with the suction cups.So we'll take this, cut it in half and we'll just focus on the plug end. We'll separate our wires, strip back the insulation from both ends, take ring terminals and crimp them down. Now we can use these ring terminals to attach them directly to our battery.The wire with the white stripe, that's our positive. We'll use that one last and do the negative one first. So undo the nut from our negative terminal on our battery, put the ring terminal on the stud, place the wire for our winch back on, replace the nut and we'll snug this down. Do the same for the positive.We'll take our connector from the solar array and then the connector that we have permanently attached to our battery and we will plug the two in together. As you can see with our connector plugged in, this flashing blue light means that our battery is being charged and maintained by the solar panel.Okay, now that our connections are made and we're plugged in, I'm going to reinstall our battery box lid. And that completes your look at and being shown how to install the Performance Tool 2 1/2 watt solar battery charger, part number PTW2997.

Everything I ordered came in one box and was all in good condition. The delivery time was great. I have used etrailer.com now for many things needed for my truck and travel trailer. They never disappoint. This service is awesome. They answer questions with there help line and give lots of documentation to help with setting up and using your purchase. Many of the brick and mortar stores need to learn how to serve the customers as well as etrailer does. 486563

First of all, GREAT customer service from this dealer. Answered questions, quick product delivery, etc. Definitely use them again. I plan to use this item for trickle charge RV battery during winter storage. The wiring is long enough to reach the battery with the solar panel sitting on the dashboard. 581815

First and foremost etrailer rocks. Excellent experience as always. The solar panel I am not happy with. I keep the panel zip tied in my dump trailer, I am assuming that I will be replacing this every year or so from damage. I assumed it had a standard two prong 12v disconnect. I bought a quick connect that attaches to the studs of the battery... it doesn't work! etrailer customer support confirmed it. Keeping the alligator clamps on all the time worries me, that they will bounce off. 733784

This is a neat little item that I'm looking forward to setting up. It appears to be exactly as advertised and best of all is less expensive than what competitor's have to offer. This is probably the forth or fifth item I've purchased from etrailer over the course of four months and it won't be my last. Buying something from an online business for the first time can be stress producing. It's easy to wonder if the quality will be as good as advertised. Or what happens if I don't actually like it? Or what about a warranty? Or what about a return? Let me tell you that etrailer's customer service is second to none. If there was a rating for 10 stars etrailer would qualify. From what I've experienced any concerns I've had have always been dealt with quickly, thoroughly, and with a cheerful attitude. And that's impressive! etrailer is my first, and usually only stop for trailer needs. 678569

I had it connected to a bumper hitch 14' dump trailer that uses a 12V battery to power the hydraulics to raise and lower the dump bed. Usually plug an extension cord into the side of the battery box as it has a built in charger to charge the battery fully or use a battery charger. Since we get plenty of sunshine thought this would be a good accessory to keep the battery charged while not in use, but after having it connected to the battery for 10 days it did not charge the battery up. The blue light on the unit was blinking and I used a voltmeter to make sure the unit was putting out correct voltage and it was. Moved the unit to a battery on my lawn tractor to see if it would charge it up, same results, would not charge the battery. Will try it next on my deer feeders to see if it will charge the smaller 12v batteries as my smaller solar chargers do. Would not recommend this product. 733757


Comments
This solar charger is great for maintaining a battery when your trailer is being stored long term. It essentially provides a trickle charge to keep your battery from dying while it is not being used. To provide the battery with a small charge during shorter storage, I recommend a charger like the Go Power Eco Solar Charging System # 34273836
Go Power Eco Solar Charging System - 10 Watt Solar Panel
$56.44
. This Go Power kit has a 10 Watt panel to provide more power to your batter than the PT 2.5 Watt panel. The 10 Watt panel will still provide low enough power that you wont have to be worried about over-charging your battery.

I won't be using the battery on my fifth wheel very often, so I won't need it charged very fast or very often. But there will be times I will be relying on just the battery and not my generator or a hook up at a camp site. This will work perfectly. And when my fifth wheel is in storage and I go by to do a few things in it, I will have power because of the solar charger. 316006

So far so good the solar battery maintainer was packaged very good .Now I can’t wait to hook is up to my RV battery and see if it will maintain the charge through the winter months. The reviews on this product were good. I would have given 5 stars but I have not used it enough to see if it will truly maintain my RV battery. I give 5 stars to Etrailer for the quick ordering service they provide and the way they take care of the merchandise that they sale no matter how much it cost they packaged it very well. I will give another review after this winter to see if this solar panel will keep my battery charged. 682245

  • Best Solar Recommendation for my 2020 Forest River Wildwood 310BH
    What a nice Camper to have!! To help maintian a battery charge the 2.5-Watt Solar Battery Charger part # PTW2997 you looked at is adequate. This is just a maintenance charger though like a trickle charger it will just keep your battery from discharging it will not keep up with loads put on the system.

    The Furrion Solar port # FSPINS-BS only fits with the male connector that comes on their solar suitcase. We had issues with that product so we don't carry it and they don't have a connector available as a separate part. I reached out to them directly to confirm this.

    The Performance Tool 2.5-Watt Solar Battery Charger # PTW2997 is weatherproof and designed to be installed on the outside of a trailer. I've attached a video to assist with the install. Furrion doesn't have a plug compatible with their solar inlet available outside of their own large kits, so I recommend bypassing the Solar inlet. You can use a different style plug or simply drill a hole for the wiring and use a silicone sealant. If you have the Solar port from the manufacturer like...

  • Solar Panel Recommendation for 2018 Keystone Sprinter
    So typically trailers like yours will have a battery that the inverter can draw power from when the generator isn't running. What the solar panel can do is help keep that battery topped off. If your 2018 Keystone Sprinter is already wired for a solar panel this should already all be taken care of and all you need to do is pick out the best panel for your needs/budget. One great option is the Go Power Retreat Solar Charging System with Digital Solar Controller # 34272635 which was designed...

I recommend the Redarc In-Vehicle BCDC Battery Charger - Dual Input - DC to DC - 12V/24V - 25 Amp # 331-BCDC1225D which will allow you to have power from a solar panel amplified and will amplify the trailer battery...

You can run a generator like # 333-0005 or # BTGEN4000LPC to run off of propane. A refrigerator will normally pull about 1600 watts at start and 800 running watts.

  • Will 2.5-Watt Solar Charger Work With Two RV Batteries
    The 2.5-Watt Solar Battery Charger # PTW2997 will be able to charge a pair of 12 volt RV batteries but the issue is it can take quite some time due to the minimal output. The best option by far is the Redarc In-Vehicle BCDC Battery Charger - Dual Input - DC to DC - 12V/24V - 25 Amp # 331-BCDC1225D which will allow you to charge your auxiliary batteries from a solar panel or your vehicle battery. I have added links to video reviews for you to check out as well.

    Since you have so many batteries to charge I'd go with a kit that has more charging potential like the Go Power Eco Solar Charging System with Digital Solar Controller # 34273837 that is rated for 20 watts charging. While this won't fully charge 6 depleted batteries it would do a much better job than a 2.5 watt charger. The solar panel is then 18-1/2" long x 13-9/16" wide x 1" deep. For a 100 watt solar panel setup we have the part # 34272635 which has dimensions of 47-1/16" long x...

  • Adding a Solar Panel to Charge a Trailer Breakaway Battery
    Part # PTW2997 works great for charging your breakaway battery when the trailer is not in use. This product is easy to hook up and fairly inexpensive compared to the price of a new battery. I strongly recommend this product. We do not carry any breakaway kits that include a solar panel but adding this unit will keep your battery charged on the trailer while it is being stored. When you are going to tow, you can unhook the unit from the battery and it will be good to go while towing.

  • Would 2.5-Watt Solar Battery Charger # PTW2997 Drain Battery if Not In Sunlight
    The 2.5-Watt Solar Battery Charger # PTW2997 that you referenced would not backfeed or drain the battery it's connected to when not charging it. It does not draw anything when just connected and not in sunlight so you wouldn't have to worry about it draining your battery if left installed. It'll just charge it when it has sunlight and leave it unaffected when not in sunlight.

  • Solar Battery Charger Compatibility with 2018 Coleman Lantern 17rd Factory Furrion Solar Connector
    Furrion is the maker of that solar port # FSPINS-BS. Any solar panel like the 2.5-Watt Solar Battery Charger # PTW2997 you mentioned can be made compatible. We unfortunately do not have an adapter as Furrion doesn't offer just the connector, but you can simply adapt the connector which is simple wiring of one positive wire and one ground wire to the battery for compatibility with what comes with your solar charger.

    A solar powered charger such as # PTW2997 is a great option but can take a long time to charge a battery; especially a battery large enough to power a winch. If you go solar make sure that the battery is fully charged before winching so that the charge (hopefully) lasts the whole time you need the winch.

    Yes, the 2.5-Watt Solar Battery Charger # PTW2997 could be used to help charge a smaller motorcycle/snowmobile battery. In the instructions for this (attached link on page) it specifically mentions that this type of battery is compatible. It doesn't have an overcharge protection feature, but by design it won't over charge the battery as it doesn't put out a high enough voltage charge that would damage the battery once topped off.

    The 2.5-Watt Solar Battery Charger # PTW2997 does not have ability to charge a totally dead battery. It really only could be used to keep a battery topped off. A 2.5 watt charge would not be enough to put a solid charge on really anything.

  • Blue Light On 2.5-Watt Solar Battery Charger Stops Blinking When Connected To Battery
    In regards to the 2.5-Watt Solar Battery Charger part # PTW2997, the blue light simply means the solar panel is absorbing light. If it is connected to a charged battery then it would not absorb light to prevent overcharging therefore the blue light would no longer blink. I have attached for you below a copy of the manual which explains all of this.
