How we scored them
The Solar Score weighs performance, build, value, safety and warranty. For a connector kit, safety means stated certifications or safety-relevant features; only the IEUYO states UL and related listings, while two others state flame or heat resistance. None of the four state a warranty term. How we pick explains the weights.
| Product | Solar Score | Perf. /35 | Build /25 | Value /25 | Safety /10 | Warranty /5 |
|---|---|---|---|---|---|---|
| IEUYO Anderson Kit | 9.7 | 30 | 21 | 21 | 9 | 0 |
| Relaxweex Power Connectors | 9.6 | 32 | 20 | 21 | 4 | 0 |
| cnaodun 50A Connector Kit | 9.5 | 28 | 20 | 20 | 5 | 0 |
Scores run from 9.2 to 9.8: each product’s point total is placed on that range, so more points always means a higher score.
How to choose the best anderson connector kit
Match amperage and gauge
The IEUYO and Relaxweex assortments cover 15, 30 and 45A for AWG10-20 wire, while the cnaodun is a dedicated 50A kit for 6-10 gauge wire with boot caps. Pick the assortment for varied small wiring and the 50A kit for heavier battery leads.
Count pieces against the job
Piece counts run from 8 connectors on the cnaodun to 120 pieces on the Relaxweex. The BougeRV is a different animal: a crimper tool kit with 12 pairs of connectors rather than a pure assortment.
| Kit | Pieces | Amperages |
|---|---|---|
| IEUYO Anderson Kit | 60 pcs, 15 pairs | 15/30/45A |
| Relaxweex Power Connectors | 120 pcs | 15/30/45A |
| cnaodun 50A Connector Kit | 8 pcs | 50A |
| BougeRV Crimper Tool Kit | 12 pairs | Not stated |
Check the certifications
The IEUYO states UL, CUL, CE, REACH and RoHS with UL94 V-0 flammability, the fullest listing here. The other three state no certifications. See our mc4 vs xt60 connectors for the solar-side connector comparison.
Decide: kit or tool
If you already own a crimper, a pure connector assortment is the better buy. If not, the BougeRV pairs its tool with 12 pairs of connectors, and the Dent-de-lion more pick below adds a ratchet crimping tool with 10 pairs of 45A connectors.
Sizing Notes
- Match the connector amperage to the circuit: 15/30/45A assortments or a dedicated 50A.
- Match the wire gauge: AWG10-20 on the assortment kits, 6-10 gauge on the 50A kit.
- For solar and RV battery leads, prefer silver-plated copper contacts as stated.
- A crimper tool kit suits first-time builders; pure connector kits suit restocking.
- Fuse the positive lead as the manual directs.
