About 2,159 Wh. CNET ran the Apex 300 on its own at 480 W and measured 2,159 Wh of the rated 2,764.8 Wh, about 78%. PCMag measured 4,959 Wh from an Apex 300 with one B300K expansion battery (5,528 Wh together), about 90%, with the load not stated. We count CNET's figure because it is the unit sold on its own.
Can the BLUETTI Apex 300 run 240 V appliances?
Yes, from its NEMA 14-50R outlet with the voltage selector set to 240 V, up to 3,840 W in total. The household outlets stay at 120 V.
Does the Apex 300 have USB ports?
No. USB-C, USB-A and 12 V outputs come from the Hub D1, sold separately. BLUETTI's US store said the hub ships from mid-December when we checked on October 25, 2026.
