Fremo x700 Portable Power Station - Review

[@ElmerFuddGun]

At 10:12 your DC load showed only 0.59V when you turned the power back on. It very briefly showed 11V then dropped to 0.59V with the same 2.88A current for 3 seconds before finally cutting out. Seemed like the power bank has a capacitor on the output that quickly drained and then it refused to try to keep it going.

[@ElmerFuddGun]

That sound at 4:54 in the right speaker sounded weird... had to play it again to check it was the video and not my speaker.

[@JulianIlett]

My editing software does that occasionally.

[@pileofstuff]

At some point, your sponsors are going to have supplied enough solar generation and battery backup for your entire neighbourhood to go off-grid.

[@JulianIlett]

Yeah, one of these days I'm going to 'caterpillar' all these power stations together in a chain (starting with the smallest one) in an attempt to discharge them all simultaneously :)

[@pileofstuff]

@@JulianIlett Then connect the last to the first and create the largest and slowest oscillator!

[@PetRatty]

@@JulianIlett make sure you do it through a grid tie inverter to your house

[@michealkinney6205]

I love the tools and testing. Thanks for an in depth review. I appreciate the data very much. Thanks!

[@grrrams]

Is there some combination of button mashing that turns those bloody sounds off?

[@JulianIlett]

I don't think so :)

[@PetRatty]

if only, open it and remove the beeper

[@JulianIlett]

Stick tape over the speaker for half volume :)

[@hi-tech-guy-1823]

@@JulianIlett Or Re-flash the ESP (32 - 8266 both support PCM Audio : WAV MP3 AAC )With better Audio Files You only other Hope is They use a TF Card - Micro SD Card for the audio files I be tempted to look inside so see if they use a Universal World Inverter design And see if it has a Pot to adjust voltage 115 > 240V > 300V

[@stoojinator]

How often are you planning on pushing a button? It's not like you have to listen to it going while the unit is on. Its a short tone once or twice per use. Hardly annoying.

[@tinplategeek1058]

Kickstarter campaign coming soon so no idea what you will get, for how much or when.

[@TheEmbeddedHobbyist]

PRnewswire state $549 starting price

[@ElmerFuddGun]

LOL at the panel specs at 4:50: _indicator light: 1_ *_white hair_* _ blue LED indicator_ _(design drawing size, subject to the actual object)_

[@hectorsantizo1595]

hello I'm thinking about buying one. What has been your experience after two years?

[@ElmerFuddGun]

So is this a *Jackery* brand? At 3:36 the wall adapter has "Jackery Japan" left of the UK CA mark.

[@DialM4Microcontrollr]

Can it be charged via USB-C? That would be great

[@dervihernandez]

Nah they just replied to someone in Kickstarter, usb c is just out only that’s the only downside.

[@matzex1819]

how do you evaluate passthrough mode ? just everything that doesnt tun off? without taking it apart there is basically no way to know if the inverter runs on the input (2 stages of voltage conversion) or even more inefficient over battery (3 stages of voltage conversion).

[@The.Doctor.Venkman]

Nice unit and good review, Julian! I wonder if the inverter specs will half for a 240VAC output once that unit is available?

[@JulianIlett]

Probably not. It's all about the Watts. The current will halve - the voltage will double. The Watts stay the same :)

[@The.Doctor.Venkman]

@@JulianIlett should have remembered my V x I = W!

[@eliannafreely5725]

Thanks, very useful review. More words for the algorithm.

[@LhDiy]

Now change it to 240V AC output and no button sounds.

[@morlanius]

How can it both be certified for the UK and have yanky sockets on it?

[@cemilbogac2974]

can I load my my bike, while i'm driving ?

[@CTCTraining1]

I like the form factor but I guess the downside is I’d also need another bag for all the cables and adapters. Thx Julian!

[@PetRatty]

thanks for the review Julian, small and lightweight. always on usb power over a couple of months is not good, what is the price as i'm not going to "sign up" just to view their products

[@JulianIlett]

The unit does shut off automatically after 8 hours.

[@JulianIlett]

Not sure about pricing yet.

[@PetRatty]

@@JulianIlett looks good, didn't realise it was kickstarter

[@pev_]

With modern LED flashlights I always wonder: A lot of them have the SOS function, but is that really something that is needed, does anybody ever use it to any avail, or is it something that has just been taken as a "must have to boost sales"??

[@BeezyKing99]

have been in an emergency situation myself.... NO ONE UNDERSTANDS the SOS pattern anymore.

[@andyjdhurley]

@@BeezyKing99 It doesn't help when many of them get it wrong - the Jackery one which I have just says 'SO, SO, SO' etc, seems like the people who wrote the code for whatever chip they use doesn't know the SOS pattern either.

[@tin2001]

The chips provide the feature, and often there's no way to ignore it. And because all the chips do it, any new chips do it too since everyone else does it.

[@true3]

As a flight medic in the Rocky Mountains for over a decade I will say first hand that the people (Rescue personnel) that need to know SOS definitely do and I have been in over 4500 search and rescue calls with about half that were successful because of light flash and SOS signaling. It only has to save one life for it to be useful and that is why I believe all portable lighting devices should have that built-in or it written on the body so people know how to use it. Just my 2 cents!

[@stoojinator]

I'd be interested in one of them. Depending on how much it is (which I couldn't see on their website). I'm guessing it will be prohibitively expensive though. But would be super handy for someone like me who spends a lot of time off grid.

[@stoojinator]

Found a price of $US550 for it. So yeah, prohibitively expensive. I'll stick to my current solution, although this is neater.

[@Seven_Joy]

Maybe you'll get a super early bird offer on August 24

[@TheEmbeddedHobbyist]

Now we know why you need to keep adding more space in your shed.

[@JulianIlett]

Indeed. I'll do a workshop tour soon on my main channel :)

[@TKomoski]

Why don't they add a bluetooth speaker into one of these things?

[@piconano]

Fun fact about those potentiometers on the electronic load. They are rated for life under 50 times usage! So don't be shocked when it dies and creates havoc. I think eevblog did a video on them. Not sure if it was him or someone else. You need to sell off some of these power inverters you've been hoarding, and get yourself a 3D printer and let your creativity juices flowing.

[@jvdmeulen]

Too bad it doesn't say if it's usb-c PD or displays supported protocols for usb-c

[@dogastus]

That was a very thorough review. Many thanks.

[@liquidus2172]

Is this a paid review?

[@Neslekkim]

clover leaf?, I always called those mickymouse connectors :)

[@techman2471]

This unit would do great as a UPS in a home/office situation. It would give you plenty of time to get home or to the office to shut down computers, test equipment, small medical equipment used at home. i would also take it on a weekender camping but not for small appliances, just charging my phones, BT devices, and a laptop. LIghting with LED strings would be good, too.

[@monicatorres6181]

Como sabe si funciona como ups?

[@MichaelBeeny]

Why does so much electronics have to make sounds for every function? I hate it. Even my car plays sounds on many functions, drives me nuts.

[@Markus0021]

You should be able to turn the sound notifications OFF, or at LEAST turn down the volume! I've seen a lot of devices recently that don't allow either option - fixed volume, always on sounds which constantly annoy the user. Quite annoying.

[@RottnRobbie]

A review of a model that hasn't even kicked off a kickstarter campaign yet. It's all vapourware until they start shipping, which might be next year, or might be never, so what's the point?

[@An.Individual]

that is a USA model

[@JulianIlett]

USA and Japan I believe

[@MrCalldean]

I love most of your content, but these are becoming paid promos, to all intents and purposes.

[@gregorythomas333]

For the love of all that's holy...they had better put a way to silence...or severely lower...the volume of that speaker!! That thing is ridiculously loud for the audio signals.

[@fredflintstone1]

Hmm american sockets you must have enough battery portable power units by now I guess, getting ready for when the Power supply goes down:-)
