Xiozugibi XT150 Extra Battery Cable for EcoFlow Delta 2/3 — 1m DC Link, High-Purity Copper

The Xiozugibi XT150 extra battery cable is a 1-meter DC link engineered to safely connect EcoFlow DELTA expansion batteries (Delta 2/2 Max/Max/3/3 Plus/3 1500) and Wave air conditioners to a host power station for reliable supplemental power.

This compact cable is made to deliver a tight, low-loss DC connection between the EcoFlow host unit and compatible expansion battery packs. It’s designed with a thick, high-purity copper core to reduce heat build-up, and a flame-retardant outer jacket to resist wear in both indoor and outdoor use. Note that DELTA Pro, Pro 3, Ultra, and 3 Max are not supported — always confirm your model before buying.

How does this cable improve power transfer compared with generic cords?

The XT150 uses a heavy-gauge, high-purity copper conductor to lower electrical resistance and keep temperatures down during heavy draw periods. That results in steadier voltage delivery and less energy loss over the short 1-meter run. Its construction prioritizes stable DC transmission for expansion battery setups without repurposing AC wiring.

• High-purity thick copper core for reduced resistance and heat.
• Optimized for DC connections between EcoFlow host and expansion battery.
• Short 1 m length minimizes voltage drop and cable clutter.
• Not intended for linking two host units or AC power use.

Is this cable compatible with my EcoFlow device?

Compatibility is limited to specific EcoFlow expansion battery systems: DELTA 2, DELTA 2 Max, DELTA Max, DELTA 3, DELTA 3 Plus, and DELTA 3 1500. Wave 2 and Wave 3 air conditioners can also be connected with this cable. DELTA Pro, Pro 3, Ultra, and 3 Max are excluded, so check your unit’s model name and connection port before ordering.

• Works with: Delta 2 / 2 Max / Max / 3 / 3 Plus / 3 1500 expansion batteries.
• Also compatible with Wave 2 and Wave 3 air conditioners.
• Not compatible with Delta Pro, Pro 3, Ultra, 3 Max models.
• Confirm model and port type on your EcoFlow device prior to purchase.

How durable and safe is the XT150 for outdoor use?

The cable is built with a flame-retardant outer jacket that resists abrasion and aging, which helps maintain a reliable connection in variable environments. Coupled with the low-resistance copper core, the overall design manages heat more effectively, reducing stress on connectors during extended operation. While robust, it’s intended for DC link use only and should be routed and secured to avoid mechanical damage.

• Flame-retardant, wear-resistant outer layer for extended service life.
• Low-heat transmission minimizes thermal stress on connections.
• 1 m length reduces the risk of trip hazards and loose loops.
• Not a substitute for AC cabling; avoid using between host units.

What does the installation and day-to-day use look like?

Installation is straightforward: plug the XT150 into the expansion battery’s XT150 port and the matching port on the EcoFlow host. The short length keeps the battery and station close for neat placement, and the flexible insulation makes routing around corners easy. For safety, ensure both devices are powered down or in standby before connecting or disconnecting the cable.

• Plug-and-play DC connection to the host unit and expansion battery.
• 1 m length simplifies positioning and keeps cable tidy.
• Flexible jacket allows easy routing without kinking.
• Power down devices before connecting or disconnecting for safety.

Who this is for: The Xiozugibi XT150 extra battery cable is ideal for EcoFlow owners who use compatible DELTA expansion batteries or Wave air conditioners and need a short, reliable DC link for backup power setups. It suits campers, van-lifers, off-grid homeowners, and professionals who demand stable, low-heat power delivery in compact installations. If your system includes a DELTA Pro, Pro 3, Ultra, or 3 Max, choose a cable specified for those models instead.
