LHT2220 vs HJ604C: Choose the Cutting Format and Charging Routine
Choose LHT2220 for hedge-focused work that suits a long blade and separate-pack charging. Choose HJ604C for grass-edge detail plus small shrub touch-ups, accepting its shorter hedge blade and tool-connected recharge routine. Both are cordless; that alone does not settle this choice.

The buying question
Do you need a long hedge blade or grass-shear conversion, and where do you want to charge the battery?
LHT2220 pairs a long hedge blade with separate-pack charging; HJ604C offers grass-and-hedge conversion but has a shorter hedge blade and tool-connected charging.
Quick verdict
Choose BLACK+DECKER LHT2220 kit if
- You want the long hedge-blade format rather than a convertible grass-detail tool.
- Charging a removable pack separately from the trimmer matters.
Choose Sun Joe HJ604C if
- One tool needs to switch between grass-shear and short hedge-trimmer attachments.
- Light touch-up work fits your garden and you can set the complete tool aside to charge.
When the recommendation changes
- Grass-shear conversion becomes a requirement.
- The intended stems exceed the chosen tool’s stated limit.
- Charging the complete tool at the available location is inconvenient.
The differences that matter
Blade And Task Fit
What this changes: Start with the work: a hedge-focused job favors the longer LHT2220 blade format; grass-edge detail plus small shrub touch-ups favors HJ604C conversion. Its shorter hedge blade is the compromise. The stated limits exclude unsuitable stems; they do not measure speed or cutting quality.[1, 2, 3, 4]
Battery Charging Workflow
BLACK+DECKER LHT2220 kit
Remove the battery pack from the tool and place it in its designated charger. The documented LHT2220 kit includes one battery and charger.[2, 1]
Sun Joe HJ604C
Connect the supplied charger to the charging socket on the tool. The manual prohibits using the tool during charging.[4]
What this changes: Both are cordless during use. LHT2220 lets you charge the pack separately from the trimmer; HJ604C requires setting the complete tool aside at its charging location. Prefer the routine that fits your setup, without assuming either lasts longer or charges faster.[2, 1, 4]
Best for your routine
A hedge-focused cordless tool with separate-pack charging
Best fit: BLACK+DECKER LHT2220 kit
Based on listed features, not comparative testing.
LHT2220 combines the long hedge blade with removable-pack charging. Choose it for those requirements, not as a substitute for grass-shear conversion.
Grass edges and small shrub touch-ups with the same tool
Best fit: Sun Joe HJ604C
Based on listed features, not comparative testing.
HJ604C supplies both blade formats. Accept the shorter hedge attachment and set the tool aside when it needs charging.
Value and trade-offs
One or both observed offers have eligibility conditions, so no unrestricted price difference is shown.
A higher price is justified only if the cutting format or charging arrangement solves your actual task. Cordless operation is common to both.
There is insufficient verified price history for a purchase-timing recommendation.
Limitations
- This is a feature-fit comparison, not a hands-on cutting test. No speed, finish, runtime, charging-speed or durability winner is established.
- The HJ604C store page gives conflicting weight figures, and its manual gives differing charge-duration guidance; neither is used to rank these tools.
- Follow each matching manual’s handling, blade-change and charging restrictions. Do not exceed the model’s cutting limit or use blade length to justify unsafe reaching.
Questions shoppers ask
Can an extra battery make the LHT2220 kit a two-pack setup?
The documented kit includes one pack. Any additional compatible pack is a separate purchase; confirm the exact battery and charger combination before buying. A spare does not establish uninterrupted operation.
Is the HJ604C a direct replacement for a long hedge trimmer?
Only if your work fits its short-blade, light-duty role. Grass-shear conversion adds a different task capability; it does not erase the hedge blade’s 0.3-inch limit.
What should I check in the offer?
Match LHT2220 to the battery-and-charger kit rather than a similarly named bare tool. For HJ604C, check the stated model and included grass blade, hedge blade and charger. Confirm the selected offer’s contents before ordering.
