Tow Tuff TMD-35ETD8 Electric Trailer Dolly Charging the Battery 

This is what the TowTuff charger says on the back, if you still need a pic of it let me know and I'll post a video about charging it (but it'll take a few days). Model: XVE-2880200 Input: AC100-240v 50/60Hz 1.5A Max Output: 28.8V 2.0A 57.6W (XV-2103020141)

@BM22TechReview really what I need to know is what the polarity on the male side is. On the sticker is it (+) - [ - ] or ( - ) - [ + ]

I'll see what I can do.

I understand this problem, as I've had it myself a couple of times when backing a heavy Wells Cargo trailer into my garage; I'm also dealing with a slight incline. The power of the bigger drive wheels digs in and lifts the small wheels off the ground. Tow Tuff's disclaimer for this, is to only use this on flat surfaces. But clearly, that is not really a practical answer for this issue. When possible, I put my foot on the foot bar, which works well on flat surfaces, but not so much on inclines. You could try using a counterweight such as a cinderblock or a bucket full of heavy items bungee corded to the frame over the small wheel. I've seen a pic where someone bolted a piece of steel (foot long piece of railroad track) to the frame above the wheel. But in the big scheme of things, as long as you have control over the dolly, small wheels on the ground or not it should be fine either way. The big "wheel problem" I've had with this when moving my small 13-foot boat, is that it doesn't have much tongue weight, since most of the boat's weight being at the rear with the outboard motor, on some inclines my drive-wheels sometimes lift off the ground, resulting in no control at all; I had to put a heavy toolbox on the tongue to keep the big wheels on the ground.

Do you mean, how does it work, as in good or bad? Or how does it actually work? As for good or bad, it works great for what I'm using it for. I'm only using it for a 13-foot Smoker Craft Alaskan boat, so it's nowhere near the weight limit for this model. But against the manufacturer's recommendations, I am using this up and down a slight incline to get the boat into my garage, and I had no problem controlling it.

You'd need to have the tongue weight and reach to make it work.

You could try contacting TowTuff to get a new one. On the back of the charger it says: XVE, Model: XVE-2880200, Output: 28.8V, 2.0A, 57.6W

what does the line in information give you is it solid circle with a line around it to an open circle or the other way round?
