Choosing a portable EV charger usually comes down to two practical questions: how far is your parking spot from the outlet, and how much do you want to spend? These two J1772 chargers both deliver 16A for Level 1 and Level 2 charging, but they answer those questions very differently. The 28-foot portable charger offers a long cable and outdoor-friendly protection; the VDLPOWER 20ft costs less than half as much and keeps things simple.
Quick verdict
If you need maximum reach and a tougher exterior, get the 28-foot portable charger. It gives you an extra eight feet of cable, an IP66 rating, and a 4-level current selector. If your outlet is close to your car and you prioritize price, get the VDLPOWER 20ft. It's $56 cheaper and still gives you a full 16A charge.

Where each product wins
The 28-foot portable charger wins for reach and outdoor use
With a 28-foot cable, you can park further from the wall, and the IP66 water and dust resistance lets you charge confidently outside. The four current settings (8A, 10A, 13A, 16A) give you control over your circuit load, whether you're at home or camping.
The VDLPOWER 20ft wins for budget-friendly garage charging
At $49.99, it's $56 less than the longer model. The included NEMA 5-15 adapter lets you use a standard household outlet, and the NEMA 6-20 plug covers 240V Level 2 charging. Since it's a used unit with only three weeks of prior use, you're getting a nearly new charger for a lower price.
Product notes
28-ft Portable EV Charger (for those who need reach and weather resistance)
The 28-foot cable is the standout reason to choose this charger. If your EV is parked at the edge of a driveway or you share an outlet, that extra reach is a real convenience. The IP66 rating and wide operating temperature range (-30°C to 45°C) mean it can live outside without a cover. I also like the 4-level current adjustment: you can drop to 8A if you're on a busy circuit, or push to 16A when you're in a hurry. The cable uses copper wiring and a thickened TPE flame-retardant jacket, so it feels more substantial than a basic cord. The trade-off is price: at $105.99, it costs $56 more than the VDLPOWER, so it's a bigger investment.
VDLPOWER J1772 Level 1 & 2 EV Charger 20FT
If you're charging in a garage or carport where the outlet is just a few feet away, this 20-foot model is a practical, lower-cost pick. At $49.99, it's $56 cheaper than the longer unit, which frees up budget for a wall mount or extension cord if you need one. The listing says it comes in original packaging with a user manual and warranty card, and the condition is used because the previous owner only used it for three weeks. That makes it a good candidate for someone who wants a 16A charger without paying the higher price. The included NEMA 5-15 adapter lets you plug into a standard wall outlet, and the NEMA 6-20 plug covers 240V Level 2 charging. Just keep in mind the cable is 8 feet shorter, so you'll want a closer parking spot.
Final choice by use case
For most people charging at home within 20 feet of an outlet, the VDLPOWER 20ft gives you dependable 16A charging for $56 less. Choose the 28-foot portable charger if your car parks beyond 20 feet, you charge outdoors, or you want the flexibility of adjustable current for different household circuits. Both will charge your J1772 EV, so your decision comes down to reach, protection, and price.
