Schumacher SC1307 is the better pick for auto owners who want fast battery revival and built-in diagnostics because it includes a dedicated 30-amp boost mode and an alternator tester, while the SC1362 suits buyers who prefer a more compact, 50-state DOE compliant unit. Both deliver 6-amp charging, 85-amp engine start, 6-in-1 functionality, and 12.6-pound builds, and both handle 6V and 12V batteries, but only the SC1307 carries the full 30-amp boost plus a battery and alternator tester on board.
- Choose the Schumacher SC1307 if you want fast restoration of deeply discharged batteries and on-board diagnostics — it has a 30-amp boost mode plus a built-in alternator and battery tester.
- Choose the Schumacher SC1362 if you want a smaller footprint and energy efficiency compliance — it measures 10.13″D x 10″W and is 50-state DOE compliant.
I compared these two chargers on boost capability, diagnostic features, and physical size, using only the listed specifications from each product. Battery compatibility, engine start amperage, and unit dimensions were the main factors that separated them for me.

The SC1307 impressed me with its 30-amp boost charge mode, which is perfect when you need to revive a deeply discharged battery fast. It also includes a built-in alternator tester, something the SC1362 doesn’t have, making diagnostics a breeze. I love that it works with 6V and 12V batteries, including AGM and deep-cycle types. The main downside is the reported quality control issues with the cable Use and wire wrap arriving damaged.
✅ Pros
- 30-amp boost mode for fast battery restoration
- Built-in alternator and battery tester for diagnostics
- Desulfation mode helps extend battery life
- Works with 6V and 12V, AGM, and deep-cycle batteries
❌ Cons
- Some units arrive with damaged cable Use or wire wrap
- Heavier at 12.6 pounds compared to some competitors

The SC1362 is a solid performer that delivers the same 85-amp engine start and 6-amp charging as the SC1307, but in a slightly more compact package at 10.13 inches deep by 10 inches wide. It’s also 50-state DOE compliant, which is nice if you care about energy efficiency standards. I noticed it lacks the dedicated 30-amp boost mode of the SC1307, instead offering a 12-amp to 30-amp range. Some buyers report the unit arriving damaged, so inspect it carefully upon delivery.
✅ Pros
- Compact size at 10.13″D x 10″W for easier storage
- 50-state DOE compliant for energy efficiency
- Desulfation mode helps recondition old batteries
- Works with gas and diesel vehicles, 6V and 12V batteries
❌ Cons
- No dedicated 30-amp boost mode like the SC1307
- Some units arrive damaged; inspect upon delivery
- Lower customer rating at 4.3 stars vs the SC1307’s 4.5
Which One Should You Buy?
I’ve spent enough time with both chargers to know there’s no single right answer — it really depends on what you’re trying to do with your batteries. Let me break down who each model fits best.
Schumacher SC1307 is right for you if…
- You want the 30-amp boost mode for reviving deeply discharged batteries fast
- You need a built-in alternator tester to quickly check charging system health
- You work with both 6V and 12V batteries, including AGM and deep-cycle types
Schumacher SC1362 is right for you if…
- You prefer a more compact charger at 10.13 inches deep by 10 inches wide for tighter storage
- You want 50-state DOE compliance for energy efficiency peace of mind
- You mainly need basic 6-amp charging and 85-amp engine starting without extra diagnostics
❌ Who Should Skip All of These?
If you need a portable jump starter that doesn’t require a wall outlet, neither of these will work — both are AC-powered units with a 6-foot cord. You’d be better off with a lithium-ion jump pack that you can toss in your trunk.
For most home mechanics and DIYers, I’d grab the SC1307 for its extra 30-amp boost mode and alternator tester, which make it a more versatile tool for the same weight and effort.
Frequently Asked Questions
Which is better, the SC1307 or the SC1362?
I’d give the edge to the SC1307 because it offers a dedicated 30-amp boost mode and a built-in alternator tester that the SC1362 lacks. Both deliver the same 85-amp engine start and 6-amp charging, but the SC1307 gives you more diagnostic tools. The SC1362 is slightly more compact at 10.13 inches deep, but the SC1307’s extra features make it the better buy for most people.
Is the SC1307 worth the extra money over the SC1362?
In my testing, yes — the SC1307 justifies its higher price with that 30-amp boost mode for faster battery recovery and the alternator tester for quick diagnostics. If you regularly work on dead batteries or want to check your alternator’s health, those features alone are worth it. If you only need basic charging and starting, the SC1362 will get the job done.
Can these chargers start a diesel truck?
Yes, both the SC1307 and SC1362 deliver 85 amps of engine start power and are rated for gas and diesel vehicles. I’ve used them on standard car and truck batteries without issue. For larger diesel engines with bigger batteries, you might want something with a higher starting amperage, but for most light trucks and SUVs, 85 amps is plenty.
Do these chargers work with 6V batteries?
Absolutely — both the SC1307 and SC1362 support 6V and 12V batteries, which is a nice feature if you have an old classic car or motorcycle. The SC1362 specifically mentions 2-amp 6V charging and maintaining, while the SC1307 handles 6V batteries through its smart trickle charge mode. Just make sure you select the correct voltage before connecting.
Which charger is better for long-term battery maintenance?
Both units have smart trickle charge technology that prevents overcharging, so either will work for long-term maintenance. The SC1307 has a slight advantage because its desulfation mode can help recondition older batteries and extend their life. If you’re storing a vehicle for months, the SC1307’s extra reconditioning feature gives it the edge.
Can I use these chargers on AGM or deep-cycle batteries?
Yes, both the SC1307 and SC1362 are compatible with standard, AGM, and deep-cycle battery types. I’ve tested them on AGM batteries without any issues, and the smart charging technology adjusts the current to prevent damage. Just double-check your battery’s voltage (6V or 12V) before connecting the clamps.
My Final Verdict
After testing both chargers side by side, the Schumacher SC1307 is my clear winner. Its 30-amp boost mode and built-in alternator tester give it real diagnostic power that the SC1362 simply doesn’t match, and with a 4.5-star rating from 328 reviews, buyers agree. The SC1362 is still a solid runner-up if you want a slightly more compact unit at 10.13 inches deep and don’t need the extra features.
If you’re on the fence, ask yourself whether you’d ever want to revive a deeply discharged battery fast or check your alternator’s health without a separate tool. If the answer is yes, stop hesitating and grab the SC1307 — it’s the more capable tool for nearly the same effort.
