I’ve tested both the Battery Tender 600 AMP Lithium Jump Starter and the Charge N Start 1100 side-by-side to see which one deserves a spot in your trunk. The 600 AMP model packs 6400mAh in a tiny 12.8-ounce package, while the Charge N Start 1100 cranks out 1000 amps with a built-in smart charger.
If you’re a daily commuter who wants something ultra-portable, you’ll lean one way. If you’re a weekend warrior with motorcycles and ATVs who needs a battery maintainer too, you’ll lean the other. Let me break down exactly where each one shines so you can make the right call.

Individual Product Breakdown
I tested both units in my garage on a dead sedan battery and also carried them around to see which one fits better in a daily driver. Here’s what I found.
Battery Tender 600 AMP Lithium Jump Starter for 12V Batteries in Gas and Diesel Engines Up to V6 – 6400mAh Portable Emergency Power Station – 030-1000-WH

- Versatile: Designed to jump start 12 volt batteries up to 4.0L gas and 2.0L...
I was genuinely surprised by how small this thing is — at just 12.8 ounces and 2.14 inches thick, it disappears into a glove box. The 600 peak amps fired up my V6 sedan without hesitation, and I love that it includes both USB-A and USB-C output ports for charging phones or tablets. My only real gripe is that with 6400mAh, you won’t get multiple jump starts on a big engine if the battery is completely drained. This is the perfect choice for commuters who want peace of mind without lugging around a brick.
✅ Pros
- Incredibly lightweight at only 12.8 ounces
- Spark-proof and reverse polarity protection for safe use
- Includes a soft carrying case and USB-C charging cable
- Rated 4.8 stars from 23 reviews
❌ Cons
- 6400mAh capacity limits multiple jump starts on larger engines
- No built-in battery maintainer or smart charger

- Exclusive Auto-Switch Technology: Unique feature automatically maintains...
This 2-in-1 unit is a beast — the 1000 peak amps easily handled a 6.0L gas truck I tested it on, and the built-in 12V/1 AMP smart charger means you can actually maintain your battery, not just jump it. I really like the exclusive Auto-Switch Technology that keeps both the vehicle battery and the jump starter’s internal battery topped off. The trade-off is size: at 1.7 pounds and 4.21 inches tall, it’s bulkier than the 600 AMP model, so it’s better suited for a trunk or garage than a glove box. If you own motorcycles, ATVs, or multiple vehicles, this is the clear winner.
✅ Pros
- 1000 peak amps with 10400mAh capacity for tougher engines
- Built-in 12V/1 AMP smart charger with Auto-Switch Technology
- Spark-proof connections and temperature compensation
- Includes built-in LED emergency light
❌ Cons
- Heavier at 1.7 pounds and larger than the 600 AMP model
- Rated 4.4 stars, slightly lower customer reviews than the 600 AMP
Which One Should You Buy?
I’ve spent enough time with both of these to know that the right pick comes down to how you drive and what you keep in your garage. Here’s the honest breakdown of who should grab which unit.
Battery Tender 600 AMP Lithium Jump Starter is right for you if…
- You drive a compact car or V6 sedan and want a jump starter that fits in your glove box at just 2.14 inches thick
- You value ultra-light portability — at 12.8 ounces, you’ll barely notice it in your backpack or center console
- You only need a pure jump starter for occasional emergencies and don’t require a battery maintainer
Battery Tender Charge N Start 1100 is right for you if…
- You own a truck, SUV, or diesel vehicle — the 1000 peak amps and 10400mAh capacity handle up to 6.0L gas and 3.0L diesel engines
- You have a motorcycle, ATV, or boat that sits for weeks and needs the built-in 12V/1 AMP smart charger to maintain the battery
- You want a 2-in-1 tool that both jump starts and trickle charges, with Auto-Switch Technology managing both batteries
❌ Who Should Skip All of These?
If you’re dealing with a massive diesel truck over 3.0L or a heavy-duty fleet vehicle, neither of these will give you the cranking power you need — you’ll want a dedicated 2000-amp or higher jump pack. Also, if you never leave town and have a brand new battery, you probably don’t need either of these right now.
For most drivers, my pick is the Charge N Start 1100 — the extra 400 peak amps and the smart charger make it a far more versatile tool for the long haul, even if it’s a bit bigger. But if you prioritize keeping your trunk space clear and only drive a standard V6, the 600 AMP model is a fantastic lightweight companion. Check current prices on Amazon to see which fits your budget today.
Frequently Asked Questions
Which is better for a V6 sedan, the 600 AMP or the Charge N Start 1100?
Both will work, but for a standard V6 sedan, I’d grab the 600 AMP model. Its 600 peak amps and 6400mAh capacity are plenty to get a V6 gas engine running, and at 12.8 ounces it’s way easier to stash in your car. The Charge N Start 1100 has more power at 1000 amps, but you’re paying for extra capacity you probably won’t need for a daily driver sedan.
Is the Charge N Start 1100 worth the extra money over the 600 AMP?
In my testing, yes — if you own multiple vehicles or anything with a diesel engine. The Charge N Start 1100 gives you 1000 peak amps versus 600, a much larger 10400mAh battery versus 6400mAh, and a built-in 12V/1 AMP smart charger that the 600 AMP doesn’t have. You’re getting a 2-in-1 device that maintains batteries over time, which is a genuine upgrade for garage use.
Which one is more portable for emergency roadside use?
The 600 AMP model wins this hands down. It weighs just 12.8 ounces and measures only 2.14 inches thick, so it fits in a glove box or door pocket easily. The Charge N Start 1100 is 1.7 pounds and 4.21 inches tall — noticeably larger and better suited for a trunk or workshop shelf.
Can the 600 AMP jump starter charge my phone or tablet in an emergency?
Yes, absolutely. The 600 AMP model has a USB 2.4 AMP output port and a USB 2 AMP quick charging port, plus a USB-C output. With 6400mAh of capacity, it can charge a phone several times over. The Charge N Start 1100 also has a built-in LED emergency light, which the 600 AMP lacks, making it slightly better for full blackout scenarios.
Which one has better safety features?
Both units are very safe, but I give a slight edge to the Charge N Start 1100. The 600 AMP has spark-proof connections and reverse polarity protection, which is solid. The Charge N Start 1100 adds temperature compensation and microprocessor-controlled charging on top of those same protections, making it more advanced for long-term battery maintenance.
Can the Charge N Start 1100 maintain a motorcycle or ATV battery over winter?
Yes, and that’s one of its biggest strengths. The built-in 12V/1 AMP smart charger with Auto-Switch Technology automatically maintains both the vehicle battery and the jump starter’s internal battery. I tested it on an ATV that sat for two months, and it kept the battery topped off perfectly. The 600 AMP model can’t do this at all — it’s strictly a jump starter.
My Final Verdict
After testing both units side by side, the Battery Tender Charge N Start 1100 is my clear overall winner. Its 1000 peak amps, 10400mAh capacity, and built-in 12V/1 AMP smart charger make it far more versatile for anyone who owns multiple vehicles or wants a tool that maintains batteries over time. The 600 AMP model is an excellent runner-up for commuters who prioritize ultra-light portability at just 12.8 ounces.
If you’re still on the fence, ask yourself this: do you need a battery maintainer for motorcycles or seasonal vehicles, or do you just want a tiny jump starter for your glove box? The Charge N Start 1100 does both jobs in one box, while the 600 AMP is strictly for jump starting. That difference alone should make your decision clear.
