    Default Delta 1300 power unit recharges to 80% in 45 minutes!

    https://www.takealot.com/ecoflow-del...n/PLID70439607


    I was amazed to see that this portable power unit recharges so quickly.
    It has a 1260 Wh (50.4V)Lithium Ion cell type 18650

    According to a piece on the web the Delta recharges without an AC power inverter (a power brick); it uses the same sort of cable as a desktop PC. The company says by passing through the inverter directly, the Delta can increase charging speed to more than 10 times the traditional AC to DC adapter cable. This also means it’s easier to replace a lost charging cable.

    Can someone explain how they have done this?

    Some of the specs:
    Recharge phone up to 140 times
    Microwave oven (1300W) up to 2 hours
    Refridgerator / Freezer (150W) up to 20 hours
    Flat screen TV (120W) 12+ hours
    Hairdryer (1600W) up to 2 hours
    Recharge laptop (150W) 23+ times
    Power drill (900W) up to 2 hours

    ? 800 Cycles (60%)
    Input sources to re-charge
    - Solar 400W, 10 - 65V DC, 10A max.
    - Cigarette Lighter 12V / 24V, 10A max.
    - Mains AC 220V
    - Re-charge 0 - 80% within 1 hour (AC mains)
    - Fully charged under 2 hours (AC mains)

    It has a 1280Wh lithium battery with 1800W inverter (can peak/surge to 3300W).

    The claim of 1hr to 80% charge, but 2hrs to 100% does not really make sense for lithium.

    My guess is that it has a 600-700W AC-DC charger (amps depends on internal battery voltage).

    Using/discharging it at max 1280W for 1 hour to flat is ok, but I'd not recommend putting higher loads on it for prolonged times. That would be discharging too fast (in my opinion).

    Inverter is pure sine wave. Nice.


    Looks like a nice product, but quite pricey.


    Thanks for sharing

    After more reading:
    - Fully charge in 1.6hrs at 1200W using AC.
    - Internally it has 18650 cells connected for 50.4V. So builtin charger is 20-25A.
    - Can only do 800 cycles. Not great for lithium, but that's probably their guarantee because they are really pushing it hard for that fast charge rate and 1800-3300W inverter/discharge.

    Is there a 230V ac model as the ones I see on www.ecoflow.com is 110Vac 60Hz for US market...?

    Yes there is a 220v version…we actually have been testing them extensively…the unit that you referring to the Delta 1300 charges from 0-80% in an hour and 0-100% 1.5 hrs (our Demo/Test unit)
    Our shipment has just landed…if you in the Cape Town area you are welcome to pop me DM…

    I think we see all the latest specs for LFP but the 18650 have less cycles. About 700 cycles in laptops a few years ago Sony rate their cells 53% cap left after 300 cycles.

    Thanks for the info.

    Then those should be fine for occasional use, but if (when?) load shedding becomes a permanent daily occurrence, it would last for 1 or maybe 2years and capacity will degrade daily.

    On Stage 8 we will have between 4.8 and 2.9 cycles per day (depending on where you live)...

    LS for 10 hours a day would be the wrong application of this unit.
