Finding the best commercial battery charger is no easy task, especially given the wide range in quality and specifications of the units available today. Industrial battery chargers are high powered units capable of charging fully depleted car or truck batteries within a few short hours, and some are able to maintain the batteries of an entire fleet vehicles while they’re in for service or repair. We’ll help you find the best charger to meet your particular commercial needs.

How to recondition a car battery at home? This is a question we get asked all the time, so much so that we decided to create a definitive guide on the topic.

I decided to do something a little different here on JumpStarterExpert - trolling motor batteries reviews.  It is something I am interested in and thought I would share with you a 2020 updated review of these nifty pieces of kit.

In your driving experience, there will be times when you are confronted with the need to fix your car. Sometimes, problems with the engine can occur even in a new car. On other occasions, it can also happen because your battery is old, and its power may not be sufficient at some point. The good news is that there is a myriad of different solutions out there to get your car back to running condition again. Many people jump out of their dead vehicle and try to flag down a passing driver, but if you’re in the middle of nowhere with no passing motorists, you are going to be stuck unless you have on of the best lithium ion jump starters with you. We review ten of the top rated options available today and the table below provides you with a snapshot of them. Particularly good is the Beatit G18 2000A Jump Pack and the Rugged Geek RG1000 Safety Plus 1000A.

The fact that you're here tells us that you're smart, that you're someone who likes to be prepared. Or perhaps you have felt the sting of being caught with a dead car battery and not having anyone around to help you. Either way, you're looking for a car battery booster. Well, you're in the right place as we have combed through the market to find 8 of the best.

There's no denying it, batteries are expensive, yet they have become such an integral part of so many aspects of our lives that we have no other choice than to accept their excessive prices. Rechargeable batteries curb this cost somewhat but they do require specific chargers to maximize their performance and longevity. Absorbed glass mat batteries are a particularly popular class of battery and with that comes the need for purpose-made AGM Battery Chargers.

Today we’ll be reviewing a jump starter with a rather exciting name – the Red Fuel powered by Schumacher SL65 Jump Starter!  Yes, it’s a bit of a mouth full but the real question is, does this device live up to its illustrious name, or is this one of Schumacher’s rare failures in the jump starter space? Here’s a quick summary of the review if you're in a hurry: SUMMARY: Overall, the Red Fuel SL65 is a decent, compact jump starter, with an attractive design, backed by one of the biggest names in the industry – Schumacher.  It has reasonable jump starting power for its size (400A peak, 200A cranking) and okay battery capacity (8000mAh).  It is perfectly capable of jump starting small cars (4-6 cylinder gas), motorcycles and scooters. On the negative side, by modern standards, the SL65 is somewhat limited in functionality, especially with respect to DC outlets, not having ports for charging laptops or other 12V devices.  It also lacks the ability to be recharged via a car’s cigarette lighter port and doesn’t have a cigarette lighter adapter to connect a portable air compressor or car power inverter for powering AC devices while outdoors. Pros: Striking compact design – 7.9 x 4.3 x 2.8 inchesGood jump starting power for its size – 400A peak, 4-6 cylinder cars, motorcycles, scootersExcellent safety featuresBacked by Schumacher brand Cons: Limited DC outlets – only 2X USB, no laptop charging portsCannot be recharged via a car’s cigarette lighterNo cigarette lighter outlet for powering portable air compressors, etc.Negative customer reviews about customer service

In this review we will be going in-depth, looking at both the good and the bad of the Red Fuel jump starter.  This will include a look at what customers that have bought the Red Fuel are saying about it as well as some other jump starters you might want to consider.  We’ll then end off with our conclusions about the SL65. Let’s get started!

Red Fuel Powered by Schumacher Review – The Good

Compact Design The first aspect of the Schumacher Red Fuel that grabs your attention, besides the name, is the striking design and relatively compact dimensions of the unit. At just 7.9 x 4.3 x 2.8 inches, the unit is perhaps a little large for a shirt or pants pocket, but can certainly fit into a small carry bag or backpack.  This means it can happily serve as a powerbank, in addition to its primary jump starter function, for your USB rechargeable devices.

Of course, it will also fit into the smallest of glove compartments whilst still leaving space for other essentials.  We personally love compact jump starters – we never seize to be amazed at how such small devices can actually get your engine started when you have a dead battery. We have, in fact, done an extensive review of the best lithium ion jump starters, where we go over what exactly to look for in these devices to be sure you're making the best choice for your vehicle. We also compare them to their much larger SLA based cousins. Check it out - it's a good read! The size of the Schumacher stands in stark contrast to some of the company's other offerings.  The DSR 122, for example, is a colossal unit, although it does include a battery charger and it will last a fair bit longer between charges!

Reasonable Jump Starting Ability So with this small size, you might be asking “How well does the Red Fuel SL65 actually perform? Is it only really capable of jump starting my daughter’s scooter or will it actually work on my car as well?” Well, the unit has a reported 400A peak jump starting current and 200A of cranking current.  This we feel is reasonable and it should be able to get a standard 4 or 6 cylinder family car jump started without a problem.  Do not however expect it to start your Toyota Tundra or Ford F-350.  It will also struggle with most diesel engine vehicles since these require more jump starting force than gas engines. It is really important to understand the limitations of your jump starter – the Red Fuel is really only designed for small cars, motorcycles and scooters. There are jump starters with much large jump starting currents available suitable for large family vehicles, SUV and even trucks.  Some great options are the NOCO Boost HD GB70 2000 Amp and the Imazing 2500A 21000mAh Jumper Pack.  These have 5 to 6 times the jump starting current than the Red Fuel.  At the end of the day, it’s all down to what you need. Good Battery Capacity In terms of capacity, the Schumacher Red Fuel comes with 8000mAh from its lithium ion battery pack.  This is reportedly sufficient to jump start a car up to 20 times between charges.  This is seriously pushing it and we certainly wouldn’t recommend testing this out.  This capacity should also be good for charging your smart phone from flat approximately 1.5 times It is always our recommendation that you should recharge your jump starter as soon as possible after it’s been used.  This is to ensure it’s ready for an emergency and to maximize the lifespan of the device. Multi-functionality and Safety The Red Fuel Schumacher comes with a respectable feature set.  It includes 2 USB ports, one 1A and the other 2.1A so that you can charge two devices at once.  It also has a flashlight which is handy at night.  This is by no means ground-breaking by today’s standards, as discussed shortly, but a decent offering in order to keep the price of the unit down.

In terms of safety, Schumacher has really equipped the Red Fuel SL65 with all of the features including: reverse polarity, short circuit, low voltage, high temperature, and reverse charging.  You can rest assured that you will be as safe as possible when using the SL65. On the topic of safety, we have also created a step-by-step guide on how to use a portable jump starter. Follow this and you'll be sure to minimize the risk of damaging your car or your jump starter, and be as safe as possible in the process as well. Backed by One of the Biggest Names in the Business The Schumacher name has become synonymous with exceptional quality and reliability in the jump starter and battery charger industry.  You can be certain they would not risk damaging their reputation on the SL65. This should provide some peace of mind that you will indeed be getting a quality product.  It also comes with a 1 year standard warranty.

What We Don’t Like About the Schumacher Red Fuel Jump Box

Be Aware of Jump Starting Limitations Many jump starters often perform beyond expectations, beyond what they have been designed for. The Schumacher won't have much lee-way however. Just bare this mind and all will be fine – small cars such the Ford Fiesta, motorcycles and scooters will be good. Diesels are particularly difficult to crank and so more care needs to be taken when selecting a jump box for these vehicles. Follow our tutorial on how to choose the best jump starter for diesel engines to avoid disappointment in your purchase. Limited DC Outlets By todays’ standards, the Red Fuel jump box is rather limited in terms of DC outlets, only having the two USB ports.  Even at the fairly low price point of the SL65, competitors such as the DBPower DJS50 800A jump starter have, in addition to two USB ports, an outlet for charging laptops and other DC portable devices. No Cigarette Lighter Adapter Another let down is the lack of a cigarette lighter adapter both for charging the SL65 while on the go from your car and as an outlet from the unit so that you can power various 12V devices.  These include air compressors for pumping up tyres and other inflatables which would normally eliminate the need to reach to your car’s outlet.

This is incredibly handy especially when camping for blowing up inflatable mattresses or for connecting 12V DC to AC inverters for powering your AC devices.

Summary of the Customer Reviews of the SL65 Jump Box

Moving onto reviews from people who have actually purchased the Schumacher Red Fuel, based on 140+ ratings, the SL65 has received an average of 4 stars out of 5, with 67% of those being 5 star ratings.  This is respectable. Positive Reviews Most positive customer reviews mention how impressed they are with ability of the unit to reliably jump start their cars given its small size.  Some customers have even successfully used it to jump start larger cars than expected.  One customer used it on their V8 T-Bird, and another used it on their GMC Yukon Danali. Most have reported using the unit on their motorcycles and smaller cars however, with no problems experienced even after using it 5-10 times before recharging the device. Negative Reviews Some of the negative reviews mention that customer service is somewhat poor, with a slow or non-existent response from Schumacher when reporting issues with their SL65.  This is disconcerting but it should be noted that this is only the experience of some people. Be sure to register your unit with Schumacher to ensure the best support. Still further negative reviews mention that the Schumacher’s 8000mAh rating is inaccurate – that it doesn’t provide the expected charging duration for their phones, tablets, etc. Other negative reviews say that after fully recharging the Red Fuel SL65, and then not using it for more than a month, that the unit was “dead” and would not even accept a charge.  We see this time and again here at JumpStarterExpert.com.  It is vital that you recharge your jump starter every month while in storage, even if it is not used at all.  Jump starters experience self-discharge which is a natural, unavoidable phenomenon with ALL battery powered devices.  Your cell phones, for instance, will do this as well.  To maximize the longevity of your jump starter, please follow this advice, as some manufacturers may not honour your warranty if they find that you left your unit in storage without frequently recharging it.

Other Jump Starters to Look At Besides the Schumacher SL65

DBPOWER 800A Peak 18000mAh Portable Car Jump Starter We mentioned this one above, but the DBPower 800A is really a cracking jump starter and pretty stiff competition for the SL65.  It has double the peak jump starting current rating, suitable for gas engines up to 7.2L and diesel up to 5.5L.  It also has 2 USB ports, an outlet for charging laptops, a cigarette lighter adapter and an 18000mAh battery capacity – over 2 times that of the Schumacher.

To top it off it, it comes with a staggering 3 year warranty. All this does come at a slightly higher price than the Red Fuel Schumacher, but its definitely is worth a look. Noco GB40 1000A Car Jump Box The Noco GB40 is arguably the best selling jump starter of all time, with over 7000 reviews on Amazon!  There’s a reason for this – it does exactly what it’s supposed to, it does it well, and it lasts.  Not quite as feature packed as the DBPower above, it does however deliver even more peak jump starting current – 2.5X that of the SL65.

It comes with a single USB outlet port, a 3-mode flashlight, and it can be recharged from your car’s cigarette lighter or from any USB charger.  It also has a larger internal battery than the Red Fuel Schumacher, but also costs slightly more.  The GB40 is a solid alternative to consider.

Conclusion – Should You Buy the SL65 Red Fuel?

Overall, the Red Fuel SL65 is a decent, compact jump starter, with an attractive design and backed by one of the biggest names in the industry – Schumacher.  It has reasonable jump starting power for its size and okay battery capacity.  It also has 2 USB ports, a multi-mode flashlight., and an excellent safety feature set. With a 4 star average customer rating, many customers were impressed with the unit’s performance, being able to jump start vehicles larger than anticipated, and with the device lasting at least 5-10 jump starts before being recharged. On the negative side, by modern standards, the SL65 is somewhat limited with respect to DC outlets, not having ports for charging laptops or other 12V devices.  It also lacks the ability to be recharged via a car’s cigarette lighter adapter, useful when on the go, and doesn’t have a cigarette lighter adapter to connect a portable air compressor or car power inverter for powering AC devices while outdoors. Negative customer reviews also reported somewhat poor customer service and that the 8000mAh rating is inaccurate – the device supplying less than this. The Red Fuel Powered by Schumacher SL65 jump starter is a respectable jump starter as long as you bear in mind the above limitations.  There is however stiff competition out there from the likes of the DBPOWER DJS50 Portable Car Jump Starter and the Noco Genius Boost GB40.

Vehicle batteries are confronted with severe heat, electronic loads out of their design spec. together with persistent vibration almost everyday.
