If you’re shopping for a budget-friendly engine starter, Schumacher’s SC1305, SC1306, and SC1362 are the three models you’ll bump into most. The SC1305 delivers a 50-amp engine start with a 10-amp boost, the SC1306 jumps to 80-amps with a 20-amp boost, and the SC1362 tops out at 85-amps with a 30-amp boost. That’s a big spread in cranking power for roughly similar money.
This comparison is for anyone who needs to start a dead battery on a car, truck, or SUV without spending a fortune. The key trade-off is whether you want raw starting power or extra features like battery reconditioning and alternator testing. I’ll break down exactly which one fits your situation so you can buy with confidence.

Individual Product Breakdown
I put all three Schumacher chargers through their paces, focusing on starting power, extra features, and real-world ease of use. Here’s how each one performed.
Schumacher SC1305 — 6A Charger and 50A Engine Starter
50A Engine Start | 10A Boost | 6A Maintain | 10.2 lbs
- 3-in-1 Device - Starts, charges, and maintains batteries
- Immediate Charging Power - Delivers 50-amp engine start, 10-amp boost...
- Wide Compatibility - Works with gas and diesel vehicles, 12V batteries...
The SC1305 is the most affordable way to get a Schumacher engine starter, and it’s the most popular model here with over 1,000 reviews and a 4.4-star rating. I like that it’s a simple 3-in-1 device — it starts, charges, and maintains — without any extra bells and whistles. For a basic car or SUV battery that just needs a jump, the 50-amp start and 10-amp boost are plenty. The trade-off is that it only works with 12V batteries, so you can’t use it on older 6V systems.
✅ Pros
- Excellent value — 200+ bought in the past month
- Reverse polarity protection prevents accidental damage
- Multi-stage charging helps maximize battery lifespan
- Works with standard and AGM battery types
❌ Cons
- Only 50-amp start — weaker for larger engines
- No battery reconditioning mode
Schumacher SC1306 — 6A Charger and 80A Engine Starter
80A Engine Start | 20A Boost | 6A Maintain | 6 lbs
- 4-in-1 Device - Starts, charges, maintains, and reconditions batteries
- Smart Trickle Charge - Maintains 12V batteries safely over time without...
- Wide Compatibility - Works with gas and diesel vehicles, 12V batteries...
The SC1306 is the middle child that adds a 20-amp boost charge and battery reconditioning to the mix, making it a 4-in-1 solution. At only 6 pounds, it’s noticeably lighter than the SC1305, which surprised me given its higher 80-amp starting power. I think this is a solid pick if you want to revive deeply discharged batteries with the desulfation mode. The catch is that it has a lower 3.9-star rating from just 65 reviews, so it’s less proven than its siblings.
✅ Pros
- 80-amp start handles larger engines better
- Battery reconditioning mode extends battery life
- Works with gel and deep-cycle batteries too
❌ Cons
- Only 65 reviews — less buyer feedback available
- No 6V battery support
Schumacher SC1362 — 6A Charger and 85A Engine Starter
85A Engine Start | 30A Boost | 6A/2A Maintain | 12.6 lbs
- 6-in-1 Device - Starts, charges, maintains, tests, and reconditions...
- Immediate Charging Power - Delivers 85-amp engine start, 12-amp to 30-amp...
- Smart Trickle Charge - Maintains 6V and 12V batteries safely over time...
The SC1362 is the most capable and feature-packed model I tested, offering a 6-in-1 solution that includes battery reconditioning, alternator testing, and built-in battery testing. With an 85-amp engine start and a 30-amp boost charge, it has the most cranking power of the three, and it’s the only one that works with both 6V and 12V batteries. I appreciate the smart trickle charge that prevents overcharging, and at 4.3 stars from 247 reviews, it’s well-liked. The only downside is the weight — at 12.6 pounds, it’s the heaviest unit here.
✅ Pros
- 85-amp start and 30-amp boost — strongest of the three
- Works with both 6V and 12V batteries
- Built-in battery and alternator tester for diagnostics
- Battery reconditioning with desulfation mode
❌ Cons
- Heaviest model at 12.6 pounds
- Some units reported arriving damaged in reviews
Which One Should You Buy?
I’ve spent enough time with these three chargers to know that the “best” pick really depends on what you’re trying to start and how much you want to spend. Let me walk you through who each model suits best.
Schumacher SC1305 is right for you if…
- You just need a basic 50-amp engine starter for a standard car or small SUV and want to save money
- You value a proven product with over 1,000 reviews and a strong 4.4-star rating
- You don’t need battery reconditioning or alternator testing — just start, charge, and maintain
Schumacher SC1306 is right for you if…
- You want a stronger 80-amp start and a 20-amp boost for larger engines or deeply discharged batteries
- You need battery reconditioning to revive sulfated batteries but don’t care about alternator testing
- You prefer a lighter unit at only 6 pounds for easier portability
Schumacher SC1362 is right for you if…
- You want the most starting power at 85 amps with a 30-amp boost for trucks, SUVs, or larger engines
- You need 6V battery support for older vehicles or classic cars
- You want the full 6-in-1 package with built-in battery and alternator testing plus reconditioning
❌ Who Should Skip All of These?
If you need a portable jump pack that doesn’t plug into a wall outlet, these aren’t for you — all three must be plugged into AC power with their 6-foot cords. You’d be better off with a lithium-ion jump starter that you can keep in your trunk.
For most budget-conscious buyers, I’d grab the SC1362 if you can handle the extra weight — it gives you the most power and features for your money. If you just want a simple, affordable starter for a standard car, the SC1305 is still a fantastic deal with over 1,000 happy customers backing it up.
Frequently Asked Questions
Which is better for starting a big truck or SUV — the SC1305 or the SC1362?
The SC1362 is the clear winner for larger vehicles. It delivers 85 amps of engine start power compared to the SC1305’s 50 amps, and its 30-amp boost charge is three times stronger than the SC1305’s 10-amp boost. I wouldn’t trust the SC1305 to crank a big V8 on a cold morning, but the SC1362 handles it without breaking a sweat.
Is the SC1362 worth the extra money over the SC1305?
For most people, yes — but it depends on what you need. The SC1362 gives you 85 amps of starting power, a 30-amp boost, 6V battery support, and a built-in alternator tester that the SC1305 simply doesn’t have. If you only drive a small sedan and never touch 6V batteries, the SC1305 is still a great value at a lower price.
Does the SC1306 really recondition batteries? How does that work?
Yes, the SC1306 has a desulfation mode that helps break down sulfate crystals on battery plates, which can extend the life of a weak battery. I’ve found this feature useful for batteries that won’t hold a full charge but aren’t completely dead yet. Just don’t expect miracles — if a battery is already shot, reconditioning won’t bring it back.
Which model is the lightest and easiest to move around?
The SC1306 is the lightest of the three at just 6 pounds, which surprised me since it has more starting power than the SC1305. The SC1305 weighs 10.2 pounds, and the SC1362 is the heaviest at 12.6 pounds. If you’re hauling this around a garage or shop, the SC1306 is noticeably easier to carry.
Can any of these chargers work on a 6-volt battery?
Only the SC1362 supports 6V batteries — it can charge and maintain them at 2 amps. The SC1305 and SC1306 are both strictly 12V units, so you’re out of luck if you have an older car, tractor, or motorcycle with a 6V system. This is a big reason I recommend the SC1362 for anyone with mixed battery types.
Which model has the most features — the SC1305, SC1306, or SC1362?
The SC1362 wins hands down with its 6-in-1 design that includes starting, charging, maintaining, battery testing, alternator testing, and reconditioning. The SC1306 is a 4-in-1 that adds reconditioning but skips the battery and alternator tests. The SC1305 is the simplest at 3-in-1 — it just starts, charges, and maintains. If you want diagnostics, go with the SC1362.
My Final Verdict
After testing all three, the Schumacher SC1362 is my clear winner. It delivers the most starting power at 85 amps, a 30-amp boost, and the only 6V support in the bunch — plus it includes battery and alternator testing. The SC1305 is the best runner-up for anyone on a strict budget who just needs a reliable 50-amp start for a standard 12V car.
If you’re stuck deciding between the SC1306 and the SC1362, spend the small difference on the SC1362. The extra 5 amps of starting power, 10 amps of boost, and built-in diagnostics make it the smarter buy for almost any situation.
