Schumacher 12V ProSeries Rechargeable Jump Starter - Powerful Enough to Start Semis Class 8 Vehicles

Amazon Customer: Started my dead dual battery RV on a Ford Transit chassis no problem. I like how it has the on/off switch and it displays the voltage on the battery to be jumped. Came fully charged.

Dennis: Ordered 2 so far. The first one I ordered in January is already dead. I emailed info@schumacherelectric.com to discuss warranty options two weeks ago and no one has responded.

D. JohnstonD. Johnston: THE SKINNY:
This thing is an absolute beast of a jumper!!
It’s HEFTY (23 lbs), it’s EASY to use (connect chargers, turn ignition), and it’s incredibly RELIABLE (successfully jumped a V8 sedan over a dozen times on single charge!).

ADDITIONAL INFO:
I used to write all sorts of reviews. But as I’ve gotten older (and time’s become more valuable), I generally only write a review when a product is either such garbage I feel duty-bound to warn others OR is so legit I feel can’t help but feel compelled to recommend it to others — especially when I had to go through several rejects before landing on the “good” one.

THIS is that good one!!

Can’t speak to others’ experiences, though I’m also routinely frustrated when perusing negative reviews only to discover they have NOTHING to do with the actual (working) product itself. I’ve now ORDERED (and used) TWO of these same Schumacher DSR 114s (as evidenced in my pics) and while I cannot yet speak to longevity, I can speak to the past 7 months of ownership and frequent use.

You couldn’t ask for a better situation to test this DSR 114 jumper than my current situation. I drive a 5.5...

RigoRigo: This is a very large, heavy unit, probably overkill for most home users jumping a couple cars a year, especially if you mainly jump V6 or smaller engines. The main gripe I have with this updated unit, as others have rightly pointed out, is the way this unit recharges. It uses an external charger that connects with an oddball 3 prong connector which is finicky to plug/unplug (see photos). They should have used a standard 110V male plug like previous models, and simply included a 3 prong to 110V female end to connect. The fact we need an external charger is actually a major drawback, it's just more hassle and cords, and what if we forget or misplace the charger? You might think, like I did, that having a quality 2A Automatic Charger is a plus, seeing as it could be used to charge any battery. Problem is, they failed to include a battery clamp adaptor cord, forcing us to special order that separately. Even more disappointing is the fact they did not include a 12V cigarette adapter to recharge this in a vehicle, which I presume many will want, especially those using this for commercial purposes. The failure to include the necessary adapters is annoying, but the bigger issue is the...

JOHN NOWELL: unit worked well for a couple of years then charger failed, we recharged with a smart charger but eventually the battery failed probably lasted 3 - 4 years with moderate use

Danny Badr: Works perfect. Several boosts with single charge. Small and Big Engines, no problem.

Chris M: Has good AGM battery, sturdy cable clamps & well designed cooling fan. Capable of cranking larger motors and multiple boosts between recharging. Bought this one since my brother-in-law has used same one at his automotive shop for years!

Christie: UPDATE: Nov. 2014, 4+ years. Box seems to be working fine. For a few weeks, it would only charge up to 60%, but now it's working fine, once more. When I thought it was broken, I was about to buy the exact same model. Yet, my original still jumps well after four years. Great little box.

UPDATE: Sept. 2014 At four years, the box finally failed me for the first time. I left my car lights on, and the box failed to turn over my engine. I plugged it in to 110, and it only charged up to 60%, with the readout listing 11 volts. It may have been power surges from my apartment wiring that effected the box, or perhaps just age. Like car batteries, I suppose a jump box can't last forever. I have been extremely pleased with this jumper, though. I used it frequently, often helping strangers when it appeared they needed a jump. Four full years is a good run, I think.

UPDATE: Nov. 2013. Still going strong. Jumped 3 cars camping at Black Rock this summer without a charge between. Everyone was impressed. Worth every penny.
---
UPDATE: At August of 2012 I've had this box for two years and it is still going strong. A good buy.

UPDATE: I've had this box for a year...
