## Description

The Schumacher Electric DSR ProSeries INC100 is a high-performance, professional-grade 12V battery charger and power supply engineered to meet the rigorous demands of modern automotive service environments. Whether you're performing ECU flash reprogramming, conducting diagnostics, or maintaining showroom vehicles, the INC100 delivers consistent, clean power and advanced functionality that technicians and service managers can rely on. At the heart of the INC100 is its versatile three-mode operation: Flash Reprogram Mode provides a stable, selectable output of 70 to 100 amps, ensuring uninterrupted voltage during sensitive ECU and module reprogramming. This mode is essential for preventing voltage drops that could corrupt software updates or damage vehicle electronics. Service Mode maintains a constant 13.5-volt output, ideal for supporting battery voltage during extended diagnostics, vehicle servicing, or showroom display. It prevents battery drain while preserving system memory and avoiding DTC resets. Boost Mode delivers a quick surge of energy—up to 14.4 volts—to revive deeply discharged or large-capacity batteries, reducing downtime and improving turnaround efficiency. The INC100 also functions as a battery tester, with built-in diagnostics that assess battery condition and voltage in real time. The digital display provides clear, accurate readouts of voltage and amperage, while intuitive controls allow for quick mode selection and voltage adjustments. Designed for durability and ease of use, the INC100 features a heavy-duty aluminum housing, dual cooling fans for thermal regulation, and 4-gauge, 10-foot booster cables with high-quality clamps and an Anderson connector for secure, high-current connections. The reverse polarity protection system includes an audible alarm and visual indicator to prevent accidental damage from incorrect clamp placement. Installation is simple thanks to adjustable mounting brackets, allowing the unit to be securely attached to shop lifts, workstations, or mobile carts. The 9-foot AC power cord ensures flexibility in placement, while the compact footprint makes it easy to integrate into any professional workspace. Compatible with a wide range of 12V battery types—including lead-acid, AGM, calcium, start-stop, and gel cell—the INC100 is ideal for use with cars, trucks, SUVs, motorcycles, ATVs, and marine vehicles. Whether you're managing a dealership, a repair shop, or a fleet service center, the Schumacher INC100 is the ultimate solution for stable power delivery, battery maintenance, and high-demand automotive applications.

Review: 1 year review of battery charger - I am an extremely satisfied customer and would recommend this charger to anyone. I purchased this battery charger about 1 year ago, and have waited until now to post a review because I did not want to mislead anyone. I can safely say this is one of the best products available on the market. PROS: Accurate power display Versatile charging settings Compact design for easier storage and relocation solutions Large low gauge wiring for both the charger leads and electrical outlet plug High volume twin ventilation fans and heat dissipating fins on body CONS: Battery clamping jaws may be too large for some applications Somewhat hard to understand automatic charging logic No cranking assist Working in a dealership, the shop provided chargers were completely unreliable and had no advanced charging functions. All it took was one failed charger mid programming, and I ended up spending 3-4 hours to fix a job that ended up paying 0.6 hours. I then decided that was enough and I needed to buy a heavy duty charger of my own. I wanted something compact that could fit in my tool box drawer for security reasons, and to make sure nobody would use it when I wasn't around. I also needed something with flash program functions to keep the voltage steady. This charger answered every need of mine and more. I am not sure who is the real manufacturer of this charger, but I have seen it rebranded under OTC and other automotive specific tool brands. It also uses a very similar charger function interface as the roll around Snapon EEBC500 unit, which is what drew me to this charger. But this charger's main advantage is the flash programming mode which allows the user to set the voltage from 13.0V and higher and the charger will automatically adjust amperage to suit, from 0 to as much as 70 amps. The large fans keep this unit cool which will aid in it's life and the low gauge wiring appears very strong and will hold up. There are sometimes the jaws will not fit on the battery itself and can only be used on the jump start terminals, so depending on different vehicles this may be an issue but it has not been for me as nearly all of the vehicles in the brand I work for have jump start terminals. It is likely possible to switch out the jaws anyhow. One odd thing is the automatic charging function which sometimes I don't understand. I am not sure if it uses the battery's internal resistance or is aiming for 12.6 volts 15.0 volts or what the case is, however I am confident it will not overcharge and "cook" a battery if left alone for hours. Overall I am very happy with this purchase, it is a tool that I feel is reliable and will last a long time as I use it almost everyday. Many technicians in the shop I work ask where I got the charger from as they can see by the build and functions this is a high quality product. desertcart has the most competitive price I found around and the purchase went smooth.
Review: Great product! - This battery charger/flash programmer works great. It has a nice forum factor, quality cables, and an easy to understand interface. The noise from the cooling fans aren’t intrusive to me, but I can see why some people consider them loud. Don’t let that deter you. I’ve used this for Porsche PIWIS programming and it did what I needed it to do without issue.

## Questions & Answers

**Q: The display is showing 0.0 volts. What is wrong?**
A: If the display is showing 0.0 volts, the clamps may not be making a good connection to the battery or the connections are reversed. Alternatively, the vehicle battery may be defective.

**Q: The battery is connected and the unit is on. Why isn’t there any output?**
A: This indicates that the battery is severely discharged. If your battery has less than 1 volt of charge, you must press and hold the Start/Stop button for 5 seconds.

**Q: Why did the unit suddenly shut down and refuse to turn back on?**
A: The unit has gotten too hot and the INC100’s thermal protection shut it off for safety reasons. Unplug the power cord and let the unit cool down. Make sure there is nothing obstructing the air flow to the fans.

**Q: Why does the fan make a rattling noise?**
A: Dirt and grime have built up on the fan, causing it to be unbalanced. Blow the dirt and grime off the fan blades using compressed air.

**Q: Why won’t the display and LEDs light up?**
A: The INC100 is not receiving power. Make sure the unit is securely plugged into a 120V AC outlet. Then check for an open fuse or circuit breaker supplying the AC outlet.

### ⭐⭐⭐⭐⭐ Fits the bill for vehicle coding, but it's also an awesome charger
*by T***Y on January 28, 2015*

I got this primarily to do some coding on my BMW. I am an enthusiast, not a professional, so it was a bit of a splurge (though if you think in money saved by not going to dealer, I still came out *way* ahead.) Anyway, it worked very well for that. You can actually monitor the amperage draw which I found rather neat. But I found another way that I can get a return on investment with this and it is properly charging/recovering batteries for longer life. I had a previous "Die Hard" smart charger and it was fine for simple charging if you are patient. But, I have a few motorcycles and even on maintainers, I've had battery issues from not always riding them very often. I had a rather expensive Odyssey battery that had seemed to of "died". Wouldn't take a charge on the smart charger, wouldn't hold a charger after jumping the bike, yet it really wasn't that old as far as that type of battery is concerned. I threw it on this bad boy and listened to the fan go up and down as the machine did all kinds of cycles for hours. I assumed this was the desulfation program or something. But, the battery seems to be happy again though we'll see if it continues to hold out. That right there saved me from chucking a 2-year old Odyssey battery and replacing it with another though which is more money saved. I might just get in the routine of regularly hooking this up to my more sedentary vehicles to make sure they keep a good charge and healthy condition.
