Keep this $85 gadget in your car — because nothing ruins a day like a dead battery
You’re running late, it’s raining, and the engine won’t turn over. Cue the dread. For the cost of a couple of takeout meals, Costco right now is selling a compact solution that turns a ruined morning into a five-minute problem: the Michelin Portable Jump Starter and 10,000 mAh LiFePO4 Power Bank — commonly listed at $84.99.
This isn’t just another flashy battery pack. It’s a pragmatic emergency tool that doubles as a power bank, flashlight, and — most importantly — a jump starter. If you spend any time on the road, it’s worth carving out a corner of the trunk for.
Why this one deserves a spot in your car
- It’s a true two-in-one: a 10,000 mAh LiFePO4 battery that functions as a power bank for phones and a 12V jump starter for common passenger vehicles.
- LiFePO4 chemistry is safer and longer-lived than typical lithium-ion cells, so the device is less likely to swell, overheat, or degrade quickly.
- Costco listing shows strong user sentiment: about a 4.5-star rating from 200+ reviews (availability and ratings can vary by region).
- It ships with jumper cables, a USB-C charge cable, a 12V car charger, and a storage bag — everything you’d need to stash it and forget it until needed.
- Built-in emergency lighting (including strobe and SOS modes) makes it helpful for roadside visibility at night.
What it can and can’t do
What it can do:
- Jump most small-to-mid-size passenger cars or deliver enough cranking current for typical sedans.
- Charge phones, tablets, and small USB devices when you’re away from an outlet.
- Provide emergency illumination and a visible SOS/strobe if you’re stranded at night.
What it might struggle with:
- Very large engines (big V8s, diesel trucks) or batteries in extreme cold may require a higher-capacity pack rated for higher peak amps.
- Some users report effectiveness drops in extreme subzero conditions, which isn’t unusual for portable battery tech.
- If a vehicle’s battery is completely failed (not just discharged), a jump pack might not help — it can only provide a boost, not replace a bad battery.
Practical tips for storing and using a jump starter
- Keep it charged: LiFePO4 holds charge well, but the unit should still be checked every few months. If you store it in an attached garage or trunk, a quick top-up every 3 months is reasonable.
- Learn the clamp etiquette: red to positive (+), black to negative (–) or vehicle chassis ground per the manual. Incorrect connections can damage electronics or safety systems.
- Read the manual before you need it: know the LED indicators, safety interlocks, and the recommended cranking procedure for your car.
- Keep it accessible: trunk or cargo area is fine — but put it somewhere you can get to in rain or snow without unpacking the entire trunk.
- Consider specs if you have a big vehicle: look for higher peak-amp ratings if you regularly need to service trucks, large SUVs, or diesel engines.
Practical value vs. price
At $84.99, this Michelin unit sits in the mid-range for consumer jump starters. It competes favorably because of the LiFePO4 cell chemistry and Costco’s broad return policy, plus the bundled accessories. If you compare to higher-end units with massive peak amps and air compressors, those cost more — but for everyday drivers who want a compact, reliable emergency tool, this is a sensible compromise.
Lessons from real users
- Many owners praise its reliability and long battery life for charging phones and for the occasional jump.
- Online threads show occasional reports of failure when used in extreme cold or when trying to jump very large vehicles; that’s a reminder to match the tool to your vehicle’s needs.
- Buying through Costco provides the safety net of returns and broad availability in many areas, which matters when you want to test the device risk-free.

My take
This is the kind of practical purchase that quietly repays itself the first time it saves you from waiting for a tow or borrowing cables in a parking lot. It won’t replace a professional roadside kit for heavy-duty work, but for most daily drivers it’s the best kind of insurance: inexpensive, easy to store, and genuinely useful. If you value peace of mind on the road, it’s an easy add to your car essentials.
