BLUETTI Apex 300 Power Station vs EcoFlow Delta Pro 3

Both are 240V-capable LFP power stations with 4kW-class output, but they scale differently. The BLUETTI Apex 300 has the longer-rated battery (6,000 cycles vs 4,000) and expands much further with add-on batteries, so it suits RV owners and whole-home backup setups that will grow. The EcoFlow Delta Pro 3 starts with more built-in capacity (4,096Wh vs 2,764.8Wh) and more solar input (2,600W vs 2,400W), so it suits people who want more usable energy out of the box. Owners praise both for quiet operation and running heavy loads; Apex 300 owners flag short Bluetooth range and clunky software menus, and Delta Pro 3 reviewers note its weight.

• Choose the BLUETTI Apex 300 if you want the longest-rated battery life and room to stack up to six expansion batteries for long RV stays or whole-home backup.
• Choose the EcoFlow Delta Pro 3 if you want more capacity and solar charging built in from day one and only need to add one or two extra batteries later.
