“Had been planning to purchase an Ecoflow Delta 2 for a few years now but, having purchased the little brother of this -the 521 - which allowed me to run my elderly mother's television for 4 hours and charge electric blanket when power went, I saw the special offer price on the 757 (Heavin's 40th anniversary) and went for it. Simple and robust kit. No apps, just power and Anker reliability.
The 757 only takes a maximum solar voc of 30v so you're looking at 3 x 100w or 2x200w say Renogy or Ecoworthy panels (Anker way too expensive). The new Solix 757 takes 30-60v panels and that opens up the opportunity of using 1 large domestic roof sized panel at the right voltage (between 30-60) as it will just ignore the excess amps produced.
Nonetheless, despite being only capable of 300w solar, this is a fast charging beast!! 90 mins for 1250wh. It also runs up to 1500w power at ease and higher on short surges.
Heavins were great. Perfectly packaged, lots of emails and nicely delivered.
Will be buying again and again from Heavins.”
