A European car with a CCS2 port and a row of CCS1 chargers is a mismatch that stops a road trip before it starts, and the best ccs2 adapter is the bridge that lets that car plug in and charge. This roundup compares what each listing states: DC and AC figures, temperature protection, stated certifications and warranty terms. The adapter with the strongest stated figures and the fullest protections leads, and a listing runs in the opposite direction, which the review calls out.

Where the points went
The Solar Score weighs performance, build, value, safety and warranty. For a charging adapter, safety means stated certifications, IP codes and protections such as temperature protection and short-circuit protection. Every full-data listing here states a 1 year warranty term. How we pick explains the weights.
| Product | Solar Score | Perf. /35 | Build /25 | Value /25 | Safety /10 | Warranty /5 |
|---|---|---|---|---|---|---|
| KWGARCIIT CCS1 to CCS2 500A | 9.7 | 33 | 22 | 21 | 8 | 2 |
| EVHIKING CCS1 to CCS2 400A | 9.6 | 30 | 21 | 21 | 7 | 2 |
| EVqiaoyi CCS1 to CCS2 250A | 9.6 | 28 | 21 | 20 | 7 | 2 |
| GUWIEYG CCS2 to CCS1 500A | 9.4 | 21 | 20 | 18 | 7 | 2 |
The Solar Score runs on a 9.2 minimum and a 9.8 maximum, and the weighted point total is placed on that line in proportion, so more points can only raise it.
How to choose the best ccs2 adapter
Match the direction to your car
The KWGARCIIT, EVHIKING and EVqiaoyi adapters run CCS1 to CCS2, for a European car with a CCS2 port charging at a US CCS1 station. The GUWIEYG adapter runs the other way, CCS2 to CCS1, for a CCS1 car charging from a CCS2 charger. Direction is the main filter: a reversed adapter does not help a CCS2 car at a CCS1 station. See the best J1772 Type 2 adapter guide for a related adapter type.
Read the DC figure before the AC figure
The KWGARCIIT and GUWIEYG list DC 500A at 1000V, the EVHIKING lists DC 400A at 1000V and the EVqiaoyi lists DC 250A at 1000V. The KWGARCIIT, EVHIKING and EVqiaoyi list AC at 32A; the GUWIEYG states no AC figure. A higher DC figure means a higher ceiling for fast charging, so the DC column is the place to start.
Check the temperature protection
The EVHIKING and EVqiaoyi stop charging when the temperature exceeds 85 degrees and resume when it drops below 65 degrees. The KWGARCIIT lists an operating range of -40°C to 85°C with overheat protection. The GUWIEYG lists a thermal circuit breaker that stops charging when the temperature exceeds 185 °F.
| Adapter | DC | Temp protection | Warranty |
|---|---|---|---|
| KWGARCIIT CCS1 to CCS2 500A | 500A 1000V | -40°C to 85°C | 1 year |
| EVHIKING CCS1 to CCS2 400A | 400A 1000V | Stops above 85, resumes below 65 | 1 year |
| EVqiaoyi CCS1 to CCS2 250A | 250A 1000V | Stops above 85, resumes below 65 | 1 year |
| GUWIEYG CCS2 to CCS1 500A | 500A 1000V | Breaker stops above 185 °F | 1 year |
| FOCSPROD NACS to CCS Adapter | 500A 1000V | Not stated | Not stated |
Look for a stated certification
The KWGARCIIT and GUWIEYG list IP54 and UL94 V-0. The EVqiaoyi lists a UL94-V0 shell. The EVHIKING names IEC62196 in its title. A listing that states no certification leaves that question open. A Level 2 charger needs a 240V outlet or circuit, and a licensed electrician should install or check the outlet. For the connector side, see the NACS vs J1772 adapter comparison.
Sizing Notes
- Match the DC figure to your charging: the KWGARCIIT and GUWIEYG list 500A at 1000V, the EVHIKING lists 400A at 1000V and the EVqiaoyi lists 250A at 1000V.
- Match the AC figure where stated: the KWGARCIIT, EVHIKING and EVqiaoyi list AC 32A.
- Check the direction: the KWGARCIIT, EVHIKING and EVqiaoyi run CCS1 to CCS2, while the GUWIEYG runs CCS2 to CCS1.
- Check the temperature limits: the EVHIKING and EVqiaoyi stop above 85 degrees and resume below 65 degrees, and the KWGARCIIT lists -40°C to 85°C.
FAQ: power away from the grid
Which adapter here lists the highest DC figure?
