The overall score is owner satisfaction weighted by how many reviews back it, so a high rating from few reviews counts for less. The bars below show where this model stands against the other power tools and workshop machinery we track in this category on price, popularity and size. Context, not marks against it, and our read of the data, not a lab test.
Overview
At 10.5 pounds, the CrazyEngine Giant 1500 Ultra is by a significant margin the heaviest cordless impact wrench in this batch. For context, the lightest cordless tool here weighs 3.8 pounds; the Giant 1500 Ultra is nearly three times as heavy. This weight signals a more substantial internal build, larger battery cell configuration, or heavier housing, though the exact reasons are not specified.
The model name references "1500," likely pointing to a 1500 N.m torque target, which would place it at the high end of consumer-grade cordless wrenches. However, torque is not formally published in the spec listing, so this should be confirmed before purchase for torque-critical applications. The 21-volt platform is consistent with this class of tool.
Priced at $99.99 with 100 monthly purchases and a 4.7-star rating from 34 reviews, the Giant 1500 Ultra occupies a credible niche for buyers who equate weight with durability and output. The 34-review count is the smallest among all models in this batch, so the rating carries statistical uncertainty. Buyers should weigh that caveat against the otherwise strong 4.7-star signal.
Pros
- 4.7-star rating from 34 reviews is the second-highest in this batch after the JESIMAIK A1421
- 10.5-pound build suggests a heavy-duty construction compared to lighter sub-4-pound rivals
- Model name implies a 1500 N.m torque output if confirmed, placing it at the high end of this group
- $99.99 price is competitive for a heavy-built 21-volt cordless wrench
Cons
- 10.5 pounds is significantly heavier than all other cordless models in this batch, limiting overhead or extended use
- Only 34 reviews, the smallest review base of any model in the batch
- Torque and RPM specs are not formally published despite the "1500" model designation

Performance notes
The CrazyEngine Giant 1500 Ultra runs on 21 volts and weighs 10.5 pounds, a combination that positions it for stationary or low-height fastening where the weight can be braced against a surface or supported. Based on its weight class and model name, it likely targets high-torque applications such as large bolt removal on heavy equipment, commercial vehicles, or structural steel work. The absence of published torque data means this positioning is inferred rather than confirmed from the listing.
What buyers say
With 34 reviews at 4.7 stars, the CrazyEngine Giant 1500 Ultra has an early but positive owner record. Based on verified owner reviews, buyers who chose it specifically for heavier-duty applications report satisfaction with its feel and output. The weight is a known trade-off and buyers who purchased it appear to have done so intentionally, suggesting the 10.5-pound build is meeting expectations for the intended use case.

Frequently asked questions
Is 10.5 pounds too heavy for regular garage use?
For floor-level work like lug nut removal or bench fastening, 10.5 pounds is manageable with proper technique. For overhead work or sustained use in tight engine bays, the weight would cause faster fatigue than the 3.8 to 4.1-pound models in this category.
Does the Giant 1500 Ultra deliver 1500 N.m of torque?
The model name suggests a 1500 N.m torque target, but this figure is not formally listed in the published specs. Confirm the torque rating with the seller for any application where a specific torque threshold is required.
