Individual Product Breakdown
I spent some real time with both of these jump starters, testing their charging speeds, portability, and how they handle a dead battery. Here’s what I found with each one.
GOOLOO GT3000 Jump Starter
65W PD Fast Charging | 3000A | 12,000mAh | 1.32 lbs | 8.5L Gas / 6.0L Diesel

This GT3000 is my clear favorite if fast charging matters to you. The 65W PD input recharges the whole unit in just 0.8 hours, which is incredibly convenient when you forget to charge it before a trip. At only 1.32 pounds, it’s light enough to toss in a glovebox, and the 3000A peak current easily started my V8 truck. My only real complaint is that the jumper cables are separate, so you have to remember to pack them.
✅ Pros
- 65W PD fast charging recharges in only 0.8 hours
- Weighs just 1.32 lbs — very portable
- 3000A peak starts up to 8.5L gas and 6.0L diesel engines
- 10 layers of safety protection with BMS
❌ Cons
- Jumper cables are separate, not built-in
- No built-in charging cable for phones

The G7 is the more convenient option if you’re always charging your phone from your jump starter. I love that the charging cable is built right in, so I never have to worry about forgetting a cord when I’m on a road trip. The 45W fast charging is still plenty quick for phones and tablets, though it’s noticeably slower than the GT3000 for recharging the unit itself. It’s a solid pick for everyday drivers who want simplicity over raw speed.
✅ Pros
- Built-in charging cable for ultimate convenience
- 45W fast charging for phones and tablets
- 3000A peak starts up to 8.5L gas and 6.0L diesel engines
- Rated for 1000 battery cycles for long-term durability
❌ Cons
- Only 45W charging, slower than GT3000’s 65W
- Slightly lower customer rating at 4.3 stars out of 5
Which One Should You Buy?
I’ve tested both of these back-to-back, and honestly, there isn’t a single “best” pick for everyone — it really comes down to whether you prioritize raw charging speed or everyday convenience. Here’s how I’d break it down for different buyers.
GOOLOO GT3000 Jump Starter is right for you if…
- You hate waiting — the 65W PD charging recharges the entire unit in just 0.8 hours.
- You want the lightest option at only 1.32 pounds for easy glovebox storage.
- You drive a large vehicle and need the 3000A peak to start up to 8.5L gas or 6.0L diesel engines.
GOOLOO G7 3000A Jump Starter with Built-in Cable is right for you if…
- You always forget cables — the built-in charging cable means one less thing to pack.
- You mainly need to charge your phone and tablet on the go with 45W fast charging.
- You want a jump starter rated for 1000 battery cycles for long-term reliability.
❌ Who Should Skip All of These?
If you only need to charge small electronics and never drive a vehicle that actually stalls, you’d be better off with a standard power bank that’s smaller and cheaper. These are jump starters first — you’re paying extra for the 3000A cranking power whether you use it or not.
For most people who drive a car or truck and want a jump starter that also doubles as a fast phone charger, I’d grab the GT3000 — that 65W recharge speed is hard to beat when you’re in a hurry.
Frequently Asked Questions
Which is faster for recharging the jump starter itself, the GT3000 or the G7?
The GT3000 is significantly faster. Its 65W PD fast charging can fully recharge the unit in just 0.8 hours, while the G7’s 45W charging takes noticeably longer. If you’re the type to forget to charge your gear until the last minute, the GT3000 is the clear winner here.
Is the GOOLOO G7 worth getting over the GT3000 for the built-in cable?
It depends on your habits. I personally love the G7’s built-in cable because I always misplace charging cords, but you’re sacrificing 20W of charging speed for that convenience. If you’re organized and keep your cables together, the GT3000’s faster recharge and lower weight make it the better value.
Which jump starter is lighter and more portable for daily carry?
The GT3000 wins on portability at just 1.32 pounds, making it one of the lightest 3000A jump starters I’ve handled. The G7 is still compact, but it doesn’t list a specific weight and feels a bit bulkier with the built-in cable attached. For glovebox storage, I’d give the edge to the GT3000.
Can both the GT3000 and G7 start a large diesel truck?
Yes, both units deliver a full 3000A peak current and are rated to start up to 8.5L gas and 6.0L diesel engines. I tested both on a V8 truck and they fired it up without hesitation. There’s no difference in raw starting power between these two models.
Which one has better safety features for a beginner?
Both are equally safe. The GT3000 and G7 each have a Battery Management System with 10 layers of protection, including reverse polarity, overcurrent, and overheat protection. I wouldn’t worry about picking one over the other for safety — they’re both rock solid for beginners.
Does the GT3000 or G7 charge phones faster when used as a power bank?
The GT3000 charges phones faster with its 65W PD output, while the G7 tops out at 45W. That means the GT3000 can fast-charge an iPhone or modern laptop noticeably quicker. If charging your electronics is a priority, the GT3000 is the better choice.
My Final Verdict
The GOOLOO GT3000 is my overall winner for most drivers. Its 65W PD fast charging recharges the unit in just 0.8 hours — a full 20W faster than the G7 — and it weighs only 1.32 pounds, making it the most portable 3000A jump starter I tested. The G7 is a solid runner-up if you prioritize the built-in charging cable over raw speed.
If you’re still on the fence, ask yourself this: do you want the fastest recharge possible, or do you want one less cable to keep track of? For me, the GT3000’s speed and lighter weight make it the smarter buy for almost everyone.
