90593303 Replacement Charger Review: Is It Worth Buying?

Quick Verdict

The 90593303 replacement charger does what it claims — it slots into the same space as your original and delivers power to Black+Decker and Greenworks cordless tools without any drilling or modification. Compatibility across the LI3100, GSL35, LI2000 and BDCS40G is the real selling point here. Build quality is functional rather than impressive, and it runs warm, which is worth knowing. Check current price on Amazon if you need a no-fuss replacement and don't want to hunt down an OEM charger at a premium.

What Is the 90593303 Replacement Charger?

Let's be clear on what this is: the 90593303 is a third-party replacement charger designed to work with specific Black+Decker and Greenworks cordless tools. It is not made or sold by Black+Decker or Greenworks — it's a bolt-on aftermarket solution for people whose OEM charger has died, gone missing or become unreliable. The product features a bolt-connected design that fits standard compatible hardware-store housings without the need for drilling, pressure or tearing anything apart.

That simplicity appealed to me the moment I unboxed it. My original Black+Decker charger had developed a loose connection — the kind where you have to angle the battery just right and hold your breath. Ordering a replacement from the OEM meant waiting and paying a surprisingly steep price. The 90593303 arrived in a plain brown box within two days, which felt like a small miracle compared to the original ordering experience.

Hands-On Review

I tested the 90593303 with a Black+Decker LI3100 driver I use around the garden shed. Installation was genuinely painless — I aligned the connector, secured the bolts with a small adjustable wrench, and that was it. No cursing, no stripped screws, no improvised workarounds. The original charger had been sitting on my workbench for two weeks because I dreaded the replacement process, so this alone was a win.

Charging worked as expected. Battery reached full charge overnight and the tool ran normally the next morning. What surprised me was the warmth — the charger brick runs noticeably warmer than the OEM unit did, even when idle. It's not hot enough to be dangerous, but if you have it sitting on a wooden shelf or tucked in a drawer while charging, give it some breathing room. I'd recommend leaving it on a hard surface.

The connectors feel solid once seated. There's a reassuring click rather than a loose wobble. That said, the plastics on the housing aren't what I'd call premium — they're functional and reasonably thick, but you won't mistake this for a factory part. For a replacement under this price point, that's acceptable. What matters is that it charges consistently and doesn't damage batteries, and after a week of daily use, I'm comfortable saying it passes both tests.

Will I keep using it? Yes — with a caveat. The warmth issue is worth monitoring, and I'd love to see the manufacturer add an LED charge indicator, which the listing doesn't mention. Without one, you have no visual confirmation of charge status until you physically check the battery.

Who Should Buy It?

• Homeowners who need a quick, affordable replacement for a dead or dying Black+Decker or Greenworks cordless tool charger
• DIY enthusiasts who prefer to handle simple tool repairs themselves rather than sourcing expensive OEM parts
• People with older cordless tools whose OEM chargers are discontinued or hard to find in local stores
• Renters or casual users who don't want to invest in a brand-new tool just because the charger failed
• Skip this if you need a charger for a brand or model not explicitly listed — compatibility matters and guessing can damage your battery

Alternatives Worth Considering

OEM Black+Decker replacement charger — If your tool is still under warranty or you want guaranteed compatibility and build quality, the official OEM unit is the safer bet. You'll pay more, but you skip the after-sales back-and-forth.

Greenworks 40V charger (for BDCS40G owners) — If you own multiple Greenworks tools and want a unified charging solution, a branded Greenworks charger ensures consistent performance across your tool lineup.

Multibrand universal charger — Some universal chargers support a wider range of voltages and connector types. Worth exploring if you have tools from multiple brands and want to consolidate chargers.

FAQ

Final Verdict

The 90593303 replacement charger fills a practical gap: you need a working charger fast, and the OEM option is either too expensive or too slow to arrive. It works, it fits without modification, and the after-sales support adds a layer of confidence that some third-party sellers skimp on. The warmth during charging and the absence of an LED status indicator are genuine downsides worth factoring in. If you own one of the listed compatible models, this is a reasonable budget replacement — just give it ventilation and don't expect the polish of a factory unit.
