Frequently Asked Questions

Can the Apex 300+B300K+Hub D1 run a 1,500W space heater for how long?

With 5,529.6Wh of stored energy, a 1,500W load would theoretically last about 3.7 hours (5,529.6Wh ÷ 1,500W ≈ 3.69h) before needing a recharge, assuming 100% efficiency. Real‑world runtime will be a bit lower due to inverter losses and battery depth‑of‑discharge limits.

Is it suitable for powering an entire house during a blackout?

While the 3,840W output can handle many circuits simultaneously, the 5.5kWh capacity is limited for whole‑home loads like central AC or electric water heaters. It’s best suited for essential circuits such as lighting, refrigeration, and a few outlets rather than an entire home.

Is the $2,849 price justified for the 3,840W output and 5,529.6Wh capacity?

Compared to similar high‑capacity portable stations, the Apex bundle offers a strong watt‑hour‑per‑dollar ratio, especially with the included 700W DC Hub that adds versatility. Buyers who need sustained high power will find the cost reasonable, though casual users may find it overpriced for their needs.

How does the 700W DC Power Hub change the way you use the unit?

The hub lets you power DC devices—such as 12V refrigerators, LED lights, or CPAP machines—directly from the battery, avoiding the ~10% loss that occurs when converting to AC first. This can extend runtime for those devices and simplify wiring in RV or off‑grid setups.

Who it's not for

This isn't for you if you’re looking for a lightweight, grab‑and‑go power bank for occasional phone charging or short camping trips.
