USB ports:
18W USB C (5V 2A or 9V 2A)
12W USB A (5V 2.1A)
22.5W USBA (ambiguous: 1 5V 2.4A or 9V 2A or 15V 1.5A, unsure about the space in the first number. it's likely the 1 isn't supposed to be there)

No mention of how fast the device itself charges.

Red flags (I'm no expert, but these make me think about whether it's good quality or not and what the warranty actually is):
- warranty is 3 years, warranty is 24 months.
- *Lots* of spelling mistakes.
- Improbable features (high/low temperature protection? Doubtful. I also doubt the 24 month standby; it's possible but seems unlikely for the price point, longevity, and recommended storage conditions (40% charge) for a probably-lithium battery)

Does anyone know why the Amp rating on these are always so ridiculously high? Seems like they keep getting higher and higher over the years. Maybe I understand amps incorrectly but an average car battery can only deliver around 800cca on average and thats more than enough to start a car. Seems like maybe these grossly large numbers are just a marketing tool. Its a higher number than the other ones so it must be better right?

I paid up for a GooLoo - want to give every chance of success in that situation- which I was in the other night and had nothing.

Don't rely on inflated mAh numbers. Evaluate your jump starter based on its Wh rating and real-world performance. Proper testing will reveal whether your device can actually deliver when your engine needs it most. Many jump starters advertise large capacities like 26,800mAh, but that number alone doesn't mean much. Without the corresponding Watt-hour (Wh) rating, it's just a marketing number. What truly matters is the usable energy output.

Based on extensive testing, most of these devices only deliver about one-third of their advertised capacity. In reality, you're likely getting around 12,000 to 16,000mAh of usable energy.

High amp ratings like "1500A peak" are common, but they don't tell the full story unless:
- The boost circuit is well-designed,
- The battery cells can sustain high discharge current,
- The wiring and connectors are thick and efficient.

My 3.0L German diesel engine requires approximately 800 amps for 3 seconds during startup.

Power Calculation: 12V × 800A × (3 sec / 3600 sec) ≈ 8 Wh

So, a single crank uses about 8 watt-hours. If your jump starter is rated at 30Wh, you'll get maybe 2–3 cranks total, especially after accounting for energy lost during voltage conversion.

- Cheaper units lose 20–25% energy in the process.
- High-quality brands like NOCO typically lose 15–20%.

How to Accurately Test a Jump Starter:
1. Charge the jump starter to 100%. Use a USB power meter to ensure it's no longer drawing current.
2. Discharge it completely and record the watt-hours (Discharge Wh).
3. Calculate actual capacity in mAh: Real Capacity (mAh) = Discharge Wh ÷ 3.7V
4. Charge the device back to 100% and record the input watt-hours (Input Wh).
5. Calculate energy loss: Loss Wh = (Input Wh - Discharge Wh)
6. Calculate efficiency: Efficiency % = 100 - (Loss Wh ÷ Input Wh × 100)

LOL. most of the these similar battery starters are made in China. It gets shipped elsewhere already 95% assembled. The manufacturer will slap on a label and claim its made in another country thats all bud.

Whew, I've learned a lot here. For a long time I thought most of these boxes were handmade in Vermont by Jack & Irma's Magic Chargers, LLC.

I bought the Bookoo a week ago. Doesn't compare to my Gooloo but it's also 4x the price

Thanks for the link but it said even a German diesel engine only needs 800 amps to start. So It doesn't really answer my question. they go into the mah rating in more depth but I understand mah rating. I'm figuring anything that can do at least 800, 900 amps will turn and start just about any modern engine so I was curious about the inflated amp ratings of these being like More than a real automotive 12v car battery under the hood could even provide. like 4000, 5000, 6000 and ever higher when 800 amps would be adequate. I'm think its a marketing trick. People just think the higher the number the better so these companies keep trying to outdo the other and thats why we see these unnecessarily large amperage ratings.

Those large Amps ratings mean nothing. The ruggedness and reliability of a jump starter is all about the quality of battery, the boost circuit and the cable quality and thickness.

That what I was thinking. The ridiculously large amperage rating is basically a marketing gimmick. People who aren't tech savvy will just assume the bigger the number the better, when in actually, even just 1000 amps is likely more amperage than the battery under their hood, when fully charged, can deliver.

Everything you buy is made in China or has a Chinese part. Not sure what's the point you are trying to make? Amazon is just Chinese products with 5x the price with Amazon shipping label. Still comes from China. 🙄🙄🙄

There's a difference between 1. American company selling stuff they get made in China, 2. A Chinese company selling stuff with good reviews and customer service, and 3. fly by night Chinese companies with nonsensical names and poorly translated advertising and no customer service and their battery will catch on fire

Unfortunately in modern America that's all we get to choose from
