Wen GNA50i 50-Amp Parallel Kit
The Wen GNA50i is designed to link two Wen inverter generators, increasing the wattage available from connected outlets. It supports up to 50 amps and 6000 watts of combined output, making it a solid choice for users who already own Wen units. This kit is best for Wen enthusiasts who want a straightforward expansion path without changing brands. A potential limitation is that it’s optimized for Wen models, which may limit cross-brand flexibility.
Wen 50-Amp 12000-Watt 240V Parallel Kit (GNA240i)
This kit targets 240V inverter generators with three parallel ports, delivering up to 50A and 12000 watts. It’s best for users with 240V Wen inverters who need higher power for demanding loads, such as larger RV ACs or workshop tools. It’s not compatible with 120V-only models. If you own multiple Wen 240V units, this is an efficient upgrade path.
Champion Power Equipment 100740 ParaLINK Kit
Champion’s 100740 ParaLINK kit enables linking two 2000–3000 watt inverters, RV-ready and designed to empower two small units to run a larger load, such as an RV air conditioner. It offers a hand-tightened clamp for quick mounting and straightforward connection. Best for campers and mobile professionals who want reliable two-unit parallel capability with minimal setup. A limitation is that this kit targets Champion inverters, so cross-brand mixing may be limited.
MECMO 50 Amp Parallel Cord Kit
The MECMO kit is built to combine two inverter generators for a stronger 50A, 120V output, with a standard 120V 50A RV receptacle (14-50R) included. It is described as broadly compatible across many inverter models, including some Westinghouse and Honda units. This makes it a strong option for users who want flexible cross-brand pairing. A caution: verify compatibility with your exact generator models before purchasing.
Journeyman-Pro Generator Parallel Cables Kit
This kit targets Honda EU-series and similar inverter generators with a right-angle 6-foot cord, rated up to 40 amps and 125 volts (about 5000 watts). It’s a compact, RV-ready option that helps save space and reduce plug-stability issues. Best for small to medium loads where you own compatible Honda or EU-series models. Limitations include a lower maximum output compared with larger 50A kits.
Buying Guide
- Compatibility: Confirm the parallel kit matches your generator brands and models. Cross-brand use may be limited or require adapters.
- Electrical Output: Decide between 30A, 50A, or higher outputs based on your expected loads, such as RV ACs or workshop tools.
- Portability vs. Fixed Setup: Some kits are compact and easy to store; others emphasize quick attachment via clamps or clips.
- Receptacle Options: Look for RV outlets (14-50R) or standard 120V/240V outlets that align with your devices.
- Cable Quality: High-quality copper wiring and durable connectors extend life and ensure stable power transfer.
Frequently Asked Questions
