First Impressions for the Chapin 63924

When it comes to doing outdoor work whether it is your actual job or your hobby the idea is to make it as enjoyable as possible. That, of course, is easier said than done! It could be the weather, harsh terrain, or even an annoying client. All of those things come with the territory, and there is not much that you can do about them. What is unacceptable is if your tools are the ones continually causing you to have a bad day. Does the Chapin 63924 4-Gallon 24-volt Extended Spray Time Battery Backpack Sprayer measure up?

We’ve all been there trying to get work done without the proper tools. You end up working twice as hard and not being able to get good results consistently. When it comes to Backpack sprayers or sprayers in general pumping is a huge hassle. Even if you can find the softest tool out there, you still need to pump some iron to get it to work. Some of you may like the workout. That’s cool be on your way then. For the rest of us who have to work on acres at a time, or need a more comfortable tool in general look no further than the Chapin 63924 4-Gallon 24-volt Extended Spray Time Battery Backpack Sprayer.

This sprayer can get through all the heavy duty jobs without any real issue. Its 24-volt Lithium-ion Battery can keep spraying for up to 2 hours. Perfect for large patches of land. The 4-gallon tank has a 6-inch wide mouth funnel for filling and being able to quickly and thoroughly clean the tank. This feature could save some money as you won’t be spilling any chemicals when you pour them into the tank. It sprays at a maximum rate of between 35 to 40 psi. Perfect not only for killing weeds or fertilizing but potentially for washing cars and rising them thoroughly. It includes three nozzles so you can put that 40 psi to good use in many applications. Maybe the only drop off is that it doesn’t have a lock feature on the sprayer. Includes a built-in a 3 stage filtration system that further prevents clogging. Also allowing you to use more dense liquids without having to worry about your sprayer long term. To top it all off a pair of comfortable padded shoulder straps. Those of you who have used one of these for a while will know how important this is.

After using the Chapin 63924 Backpack Sprayer to spray some fertilizers around for a couple of hours, then wash some cars, and testing all three nozzle functions everything checks out great! The battery last as much as they say it does. It charges back up in about an hour or so. The charger attaches directly to the outlet so no issue with wires. You can buy those replacements online as well if anything ever happens without having to buy a whole new sprayer. So, that is always a little plus. As far as spraying performance at full charge you can get to spray up to 30 ft. Weight wise it is a bit heavy, but most of these are a bit heavy. If you can’t handle the weight, you could always not fill the tank up all the way. The straps make it a comfortable fit on the shoulders. At least for the 2 hours, the battery lasts. Overall a very, very positive experience with this product. We will have to see how it checks out in durability. Until now everything is right where it should be.

What does everyone else think?

We must say this is a relatively new product. So there is still not too much feedback available out there, especially concerning durability. The jury is still out on that, and that might affect experienced buyers from jumping on this sprayer. What we could corroborate in the reviews was its efficiency. People claim that they have gotten through spraying fertilizer on 1 acre of land in under 30 minutes. That also speaks to the comfort level that the product has.

What we liked

The Chapin 63924 Backpack Sprayer is an excellent sprayer overall. It works smoothly, and it is consistent. That would be the first stand out characteristic. Remember that you are not continually pumping so being able to have constant pressure to be able to spray long distance without having to press down too hard is one of its fundamental virtues. The shoulder straps were also very comfortable. Typically we wouldn’t put shoulder straps this high on the list of things we did like because they don’t have to do with the overall performance. In this case, though they are vital to you being able to keep spraying comfortably for more extended periods of time. The 6-inch mouth funnel made things start of great too. Think about this you could potentially spray over 50 gallons of liquid on just one charge. You're already making fast work out of it, why slow down for refills? The larger mouth makes it faster to refill with less waste.

What we didn't like

The biggest issue for us was still relatively minor. The shoulder straps are reasonably comfortable, but they could be a little wider with more padding, especially for the price of the sprayer. At the time of this writing, there were a few negative reviews on Amazon regarding build quality. We didn't notice this issue, and it doesn't seem to be reflected anywhere else. I'm not sure if a bad batch went through Amazon, but we'll keep an eye on this and update this review if our findings change.


I give it 3.5 stars!

The Chapin 63924 24v Battery Powered Backpack Sprayer will save you time, reduce effort along with chemical waste. We think this is an all-around win and worth your consideration.

The Chapin 63924 24v Battery Powered Backpack Sprayer is great for some jobs but we have some sprayers that may work even better for you. Take a look at some of our highest rated sprayers like this Smith Performance Sprayer or even this My4Sons sprayer. We have a backpack sprayer buying guide that might be helpful as well.
