  • Build quality may vary between batches compared to OEM chargers

Quick Verdict

The 90593303 replacement charger is a budget-friendly aftermarket option for anyone who needs to replace a lost or broken charger for Greenworks LI3100, GSL35, LI2000, or Black+Decker BDCS40G tools. It fits the connector without modification, which saves time. That said, the lack of OEM backing and unclear charging specifications mean you are accepting a bit of uncertainty. If you need certainty, spend more on a certified replacement. If price matters, this one gets the job done — but watch the fine print on the after-sales promise.

What Is the 90593303 Replacement Charger?

Let me set the scene: it is a Saturday morning, you pull your Greenworks LI3100 string trimmer out of the garage, and the battery is dead. You dig through a drawer of orphaned cables and realize the original charger went missing months ago. That is exactly the problem this product targets. The 90593303 is a generic replacement charger designed to work with several 40V lithium-ion tools from Greenworks and Black+Decker, specifically the LI3100, GSL35, LI2000, and BDCS40G models.

It uses a bolt-connected design following general industry standards, which in plain language means the connector should snap into your tool's charging port without you needing to drill, pry, or force anything. The listing calls it "simple and convenient" — I will come back to whether that holds up in practice. It is positioned as an upgrade path for anyone who cannot find an OEM charger in stock or wants to avoid the full retail price of a brand-name replacement.

Key Features

  • Compatible with Greenworks LI3100, GSL35, LI2000 and Black+Decker BDCS40G 40V tools
  • Industry-standard connector designed for direct fit — no modifications needed
  • Compact and lightweight form factor for easy storage in a toolbox or vehicle
  • DIY-friendly installation: no professional tools required
  • Generic aftermarket design at a lower price point than OEM replacements
  • Seller offers basic after-sales support for quality-related concerns

Hands-On Review

To be clear upfront — I did not have this exact unit in hand for a physical stress test, but I spent time cross-referencing the specs, user reports from similar aftermarket charger listings, and the specific compatibility claims in the product data. Here is what I can tell you.

The connector design is the make-or-break factor for any replacement charger, and the 90593303 checks the right boxes on paper. It is described as using "bolt connected parts" that follow general industry standards, which in practice means the physical fit should be solid. I have seen this phrasing before on other generic replacement parts — it is a signal that the manufacturer built to fit common port dimensions rather than guessing.

What surprised me was the lack of specific electrical specs in the listing. There is no mention of output voltage, amperage, or estimated charging time. That is a real gap. When you are dealing with lithium-ion batteries, knowing the charging current matters — too slow and you are waiting around; too fast and you risk stressing the cells. The silence on this point is disappointing, and it is the kind of thing that makes you wish the seller had included even basic specifications.

One thing I will give credit for: the versatility. Listing compatibility across four different model numbers (LI3100, GSL35, LI2000, and BDCS40G) suggests the manufacturer tested this across a range of tools rather than just slapping a label on a generic brick. Whether that testing was rigorous or just a lucky guess is impossible to verify from a product page, but the breadth is appreciated.

After the first week of researching this product, my honest takeaway is this: it is a reasonable gamble for the price if your OEM charger is gone and you need a quick fix. Do not expect frills, detailed specs, or the warm fuzzies of brand-name quality assurance. But for a tool you use seasonally, this will likely get you back up and running without breaking the bank.

Who Should Buy It?

This charger makes sense for:

  • Seasonal lawn care users who lost or wore out their original Greenworks or Black+Decker charger and need a replacement without paying full OEM prices
  • DIY homeowners who keep a spare charger in their vehicle or garden shed for on-site top-ups during long yard work sessions
  • Anyone whose original charger is backordered or no longer stocked by the manufacturer — this fills the gap while you wait
  • Rental property managers who need inexpensive backup chargers for multiple 40V tools across different units

Skip this if you need a charger for daily professional use where reliability and warranty coverage are non-negotiable. Also skip it if your tools are still under the original manufacturer's warranty — using a third-party charger could potentially void that coverage in some cases.

Alternatives Worth Considering

If the 90593303 feels like too much of an unknown, here are two paths worth exploring:

Greenworks OEM 40V Charger: The official replacement from Greenworks carries full compatibility guarantees and typically includes overcharge protection. You pay more, but you get peace of mind and a known charging time. Worth it if your tools see heavy weekly use.

Black+Decker LCB100 40V Charger: Black+Decker's own replacement unit is another certified option for BDCS40G owners specifically. It is designed for the same voltage class and will carry the same safety certifications as your original unit.

Generic Amazon Basics 40V Charger: Amazon's in-house brand sometimes stocks budget chargers with slightly more transparent specs than generic listings. Worth checking alongside this one to compare output ratings and user feedback.

FAQ

Yes — the listing specifically confirms compatibility with the Greenworks LI3100 model. The connector is designed to match the factory端口 and should seat without modification.

Final Verdict

The 90593303 replacement charger fills a real need — getting a dead or missing charger replaced without paying a premium. Its compatibility with the Greenworks LI3100, GSL35, LI2000, and Black+Decker BDCS40G covers a useful cluster of 40V tools, and the straightforward plug-in design means you will not need a mechanics background to use it. The trade-off is the usual one with generic parts: no OEM backing, no certified safety testing mentioned, and a seller support promise that is as vague as it is well-intentioned. For occasional weekend use, this charger will probably serve you fine. For anything more demanding, the extra cost of an official replacement is hard to argue against. If you decide it is worth the risk to save a few dollars, make sure you test it on a full charge cycle before you are in the middle of a job and desperate for battery power.
