Yes, I agree it's about time these solar charger power packs came with powerpole inputs. We have the Ecoflow River 2 and it's very good but as you say, the radio still needs its actual power supply, leading to slightly lower efficiency, added to which if wanting to go portable/do POTA or whatever, its another heavy thing to carry with you. and another potential source of noise and/or another thing in the chain that could fail.

G'day Hayden. Great review. I love my Delta 2 and also have the external battery. Be aware that the connector for solar input is an XT60i (note the "i" suffix). It has an extra pin between the + and - terminals.

I just got the us version. It's very similar but the AC output ports are US style. 2 of them are 3 prong with ground connector and another 4 with 2 prong connectors. I don't have the equipment to check if there's HF interference but I'd assume it's similar. I wish the 12v outputs were higher amperage, that'd be nicer for ham radio.

Them great to have. just the inverter makes RFI . I found distance and putting ferrite on extion cord right wear it plus in to power station helps. The extion cord can act as a antenna bringing more RFI threw the cord. You will need this to run that new ICOM at 200 watts. Just use long cord or build a faraday room for the powerstation . 73

It looks like they make a accessory device that connects to their power banks called a "800W alternator charger". It has three modes, charging, reverse charging and maintenance. In the "reverse charging" mode it is used to supply DC power to charge your RV batteries or use as a booster pack to start a vehicle if the vehicles battery is dead. It connects to the port on the side of the unit where you would connect the additional battery packs. Maybe there is a possibility of using this port as a high power DC output. If you connect a volt meter to the jack on the side of the unit what do you see? Or maybe you could use the 800W alternator charger module in revers charge mode to power radios. It looks to just be a DC to DC converter.

Are these a "pure sine wave" output?

[michaelross-ajfgvkrz]

Hayden, do you have some ferrites to slip over the AC output lines? If so, and that shuts the RFI up, you could then install inside the unit, right at the inverter output.

[HamRadioNCKL]

Was curious if any RFI. Looks interesting.

[vkhau]

Interesting, would like to see more testing on the HF bands.

[Clinton_Cann]

I've had the vk version of the delta 2 for a few weeks . Mine dosen't like my 300 watt pannel. I plug the car charging cable into a cig to anderson adaptor on the solar pannel. David Murray KF5QQV also known as the 8 bit guy has great reviews on the eco flow stuff. The relay switching time between ac input and battery backup is a pain if using blaupunkt tv's as shack monitors . Annoying having to turn them back on each time the relay switches sources.

[michaelross-ajfgvkrz]

How does it stack up against the Jackery ?

[VictorJenks]

I have this same Generator Battery . It is noisy if too close .

[MAMAN]

Problem with a lot of these, is that they're noisy on HF.

[bob_-gd]

Biggest downside of these for me is the lack of a higher current dc output. Seems like a silly limitation, but it seems almost every powerstation manufacturer has that 10 amp 12v dc limit

[NLSD]

The pulsing on 40 and 80m bands makes it pretty clear that this unit is utilizing PWM charging, not MPPT. MPPT is typically RF-quiet, and also more efficient. As 40m and 80m are typically what one would use in an emergency/disaster/SHTF scenario, having a big battery bank like this dumping noise onto the bands is not a good choice.

To the person that suggested ferrites: sorry, no - why should the end user have to band-aid a decision made at the engineering desk? --especially at this price point?

Bottom line, this is not a good solution for the Amateur radio community, and I'm not really sure why they would have an Amateur test a solar generator that isn't RF-quiet in the first place.

[exophoric]

pretty crazy it has to know your email address to just turn on and off switches

[phatwongaming]

I found the fans are flat out noisy, so sold it off.

[Plasmastorm_nevv]

$1500 USD??? I can make my own for half that oe even less.

[halledwardb]

Yea, i saved a bunch and grabbed a battery out of a car.
