Crivnhar Sup-18 Cordless Submersible Pump for Milwaukee 18V Batteries

Cordless: The Crivnhar Sup-18 is a battery-powered submersible pump listed for Milwaukee 18V batteries, with three selectable flow settings and an automatic low-water shutoff claim. The battery and charger are sold separately, so it suits buyers who already have a compatible battery and want a portable option for water transfer.

At a glance

  • Three claimed flow settings let users select a lower or higher transfer rate for different jobs.
  • The listing describes an automatic shutoff when water falls below 18mm, intended to limit dry running.
  • A 16.5-foot power cord and included 3/4-inch garden hose adapter provide placement and hose-connection options.
  • The listing describes 360° surround and bottom suction with a mesh filter screen for small debris.

Pros and cons

Pros

  • Cordless battery operation avoids reliance on an extension cord, provided you have a compatible battery.
  • Three flow settings and an auto-shutoff feature are specified in the listing.
  • The stated 26-foot maximum lift gives a useful reference for considering vertical transfer needs.

Cons

  • Battery and charger are not included, adding a separate requirement for operation.
  • Customer feedback reports mixed experiences with flow rate, so the stated high-mode rate may not match every user's expectations or setup.

What to know before buying

Listing details to confirm

The listing is inconsistent about motor output: one claim gives 1/6 HP, another gives 0.17 hp, and another describes a 130W motor. It also alternates between ABS, epoxy resin and plastic/stainless steel for materials. Treat these details as unresolved listing claims and confirm the intended battery compatibility, material and motor rating before purchase. The 1320 GPH figure is a stated maximum, not a guaranteed rate under every lift or hose condition.

Customer feedback highlights ease of use and positive impressions of performance, including a mention of filling water totes. Flow rate receives mixed feedback. That variation matters because the listing's 1320 GPH figure is a maximum claim and does not establish delivered flow under a buyer's hose and lift conditions.

Positive themes

  • Customer feedback describes the pump as easy to use.
  • Some feedback characterizes its performance positively.

Mixed feedback

  • Feedback on flow rate is mixed.
