The short version: $100 is the ceiling where a jump starter stops being a compromise — under it you can still get a pack that cranks your engine again and again, protects you from a wrong connection, and rides quietly in the trunk until the morning it saves the day. After weighing aggregated owner ratings and review volume across the sub-$100 field, our #1 pick is the NOCO Boost Plus GB40 — owners rate its UltraSafe clamps 4.8 across tens of thousands of reviews, and it slips in right at the $100 line. Want more amps for less? The GOOLOO GP4000 gives 4000 amps for around $80, and the TOPDON Volcano1200 is the tiny glovebox pick. Below is the full ranked field, how we rank, and the honest trade-offs.
This guide holds a hard $100 ceiling — if you want to spend even less, the best budget jump starter guide goes lower still, and for the full range including premium units see the main best portable jump starter guide. The full jump starters and battery care hub covers chargers, maintainers and the rest.

- UltraSafe spark-proof, reverse-polarity safe
- Up to 20 jump starts per charge
- USB power bank + 100-lumen LED

- 4000A, all gas / up to 10.0L diesel

How We Rank
We do not drain one battery in a parking lot and call that the whole story — a jump starter proves itself over years of dead-battery mornings and glovebox storage, so we rank by the signal that captures that: aggregated owner ratings, review volume, and the themes owners repeat, all held to a hard $100 ceiling. We weigh four things. Cranking power — the amp rating and the engine sizes owners actually report starting. Safety — reverse-polarity protection at a minimum, and spark-proof clamps where the price allows. Battery and features — capacity, jumps per charge, recharge and power-bank extras. And value — what you pay against the power and features you get, which is the whole point of shopping under $100. Prices were current at the time of writing.
The Under-$100 Jump Starters, Reviewed
1. NOCO Boost Plus GB40 (1000A) — Best Overall
The trusted name right at the ceiling. Its 1000-amp output covers a typical car, and the UltraSafe spark-proof clamps make it the safest first-timer choice. Pros: enormous review base, foolproof clamps, doubles as a power bank, strong brand backing. Cons: lowest amp rating here, and it sits right at the $100 line rather than deep under it.
2. GOOLOO GP4000 (4000A) — Best Value
The power-for-money champion. A 4000-amp output cranks far bigger engines than its price hints, with fast USB charging and a work light thrown in. Pros: huge amp output, keen price, QC and USB-C ports, well rated. Cons: clamps are not spark-proof like NOCO’s, and it is bulkier than the pocket packs.
3. TOPDON Volcano1200 (1200A) — Best Compact
The glovebox specialist. At half a pound and IP64-rated, it hides in a door pocket yet still jumps a normal car up to 15 times per charge. Pros: tiny and light, water-resistant, plenty of jumps, low price. Cons: smaller battery than the big packs, and 1200 amps is the wrong tool for large diesels.
4. Imazing Portable Jump Starter (2500A) — Best Big Battery
The power bank that also jumps. A 20,000mAh pack with an LCD gauge keeps devices alive on long hauls while holding 2500 amps in reserve. Pros: large capacity, charge display, QC 3.0 fast charging, bright SOS light. Cons: heavier for its amp class, and the LCD adds a little bulk over simpler packs.
5. AVAPOW 6000A Jump Starter — Best High-Output Budget
The max-amp bargain. Its 6000-amp output turns over big diesels and trucks that stall lesser budget packs, all for around $70. Pros: highest amps here, DC output, USB 3.0 power bank, bright light. Cons: a slightly lower rating than the top picks, and the big output flatters headline specs more than everyday car use needs.
6. NEXPOW G17 (2000A) — Best Under $70
The balanced budget all-rounder. A 2000-amp output, a QC 3.0 power bank and full safety protection in a pack that stays comfortably under $70. Pros: ample amps for cars, fast-charge power bank, safety protections, low price. Cons: a younger review base than the veterans, and no standout feature beyond solid all-round value.
How to Choose a Jump Starter Under $100
Match the amps to your engine first: 1000 amps, like the GB40, is plenty for a typical car, while 4000-plus, like the GOOLOO or AVAPOW, gives real headroom for big trucks and diesels. Next, weigh safety — reverse-polarity protection is the floor, and spark-proof clamps like NOCO’s are the safest choice for anyone new to jumping a battery. Then consider size and battery: a half-pound pack like the TOPDON rides in a glovebox, while a 20,000mAh unit like the Imazing doubles as a serious power bank on road trips. Finally, hold the $100 line and lean toward packs with a large review base, the honest signal that they still fire on the cold morning you actually need them, and recharge whatever you buy every few months so it is ready.
The Verdict
For the best jump starter under $100, the NOCO Boost Plus GB40 is the one owners rate above the rest — foolproof UltraSafe clamps and tens of thousands of reviews, right at the $100 ceiling. Want more amps for less? The GOOLOO GP4000 gives 4000 amps for around $80, and the TOPDON Volcano1200 is the tiny glovebox pick. Check Price on Amazon →
