The listing for the JT08 and JT09 names no storage case and no pin caps — the adapters are supplied as the part itself. So protecting the pins between trips is a routine, not an accessory: put it away dry, keep both faces covered and uncrushed, give it one fixed home, and look at the pin faces for 30 seconds before any trip that depends on it.
Key Takeaways
- The listing includes no case or pin caps: covering the faces is your own accessory, and the routine does the real work.
- Put it away dry, in one fixed home, out from under heavy items.
- A dry wipe is the limit of pin care: no sprays, solvents or abrasives.
- Run the 30-second check before a trip — a failed adapter is retired at home, not discovered at a charger.
Why the Pin Faces Deserve the Care
An adapter is two joints, and at each joint the whole session crosses the contact faces — real contact happens at scattered points, so the faces’ condition is the session’s condition. Clean faces keep the joint’s resistance low; grit pressed in, or a face scored by rattling loose, concentrates wear where the current crowds. The damage happens between trips, in a boot, under whatever else lives there.
The Routine
- Dry before it goes away. Wipe both faces dry and let it air-dry before packing. Sealing damp inside a pouch stores the problem with the part.
- Cover the faces. The listing includes no caps, so this is your own accessory: a padded pouch or small case keeps both faces covered and stops knocks. What matters is covered faces.
- One fixed home. A boot box, a frunk corner, a seat-back pocket — not under heavy or sharp items, not stepped on, and findable in the dark at a charger. An adapter you cannot find does not charge.
- Nothing inside the faces but a wipe. No sprays, solvents or abrasives on the faces. More than a dry wipe is a question for the manufacturer, not a cleaning product.
| What storage does | What it does to the faces | The habit that answers it |
|---|---|---|
| Packed away damp | Films and corrosion marks forming unseen | Wipe and air-dry before packing |
| Loose grit around it | Faces scored as they rub | Faces covered — your own caps, pouch or case |
| Weight and sharp edges above it | Bent pins, a cracked housing | One fixed home, nothing heavy on top |
| Weeks of stillness | All of it discovered at a charger | The 30-second check below |
The 30-Second Check Before a Trip
The check belongs to the packing list, not the panic at the stall. Four looks, in order:
- Pin faces: clean, bright and dry — nothing baked on that a wipe will not lift.
- Pins: straight, firm, evenly seated — nothing bent, loose or pushed back.
- Housing and seal faces: whole and uncracked — no chips, no nicked sealing surface.
- General condition: no heat discoloration, no scorch smell, no fit that has gone sloppy.
Any fail ends the adapter’s service, not just its trip: it is retired, never packed “just in case”, never repaired at home. Sort the replacement before the journey, not during it.
The Adapters Themselves
The EVDANCE JT08 and the EVDANCE JT09 are NACS-to-CCS1 DC adapters for a car with a CCS1 inlet at a NACS DC station, including Superchargers open to that car. Both are rated up to 500 A with IP66 sealing; the JT08 is also stated at up to 1000 V, and the JT09 adds a handle — the handled form hangs neatly on a garage hook, the handleless form sits flatter in a pouch. Neither adds a case or covers, and the use conditions stand: your car maker’s approval of third-party DC adapters for your car, and a station open to your car.

Frequently Asked Questions
Can I clean the pins with contact cleaner or a brush?
None are recommended here. A dry wipe is the limit of user care; abrasives score the faces and no solvent is part of any stated care routine. A face a wipe cannot restore is a manufacturer question — or a retirement.
The adapter got wet in the car. Is it ruined?
Not necessarily. Dry it fully, then run the check: clean, bright faces and a sound housing mean ordinary damp is a storage lesson, not a failure. If water sat inside it, or anything fails the check, retire it — the sealed rating covers a seated session, not a flooded boot.
How many trips should the pins last?
No cycle count or lifespan figure is stated for these adapters, so none is quoted. Condition, not a count, decides — and damage at any age ends its service.
