It is not a pure sine wave power inverter. And a f****** story. He just has a few more little Parts in it to make it a smoother wave but it is not a pure sine wave.
It's a quadric wave converter (most simple explanation is least squares to the 4th power), which is so close to pure sine wave that it has no effect on electronics. Only way to make a pure sine wave current is to have a spinning mechanical rotor. Considering Plank times and distances, quadric is close enough for government work.
I’ve had my 240 for 3 yrs now and stopped by to confirm the solar input. With my 200w AllPowers suitcase panel I’m getting 53 watts coming in woohooo 🎊 thanks again bro love your channel. Sincerely, solo female traveler/nomad/gypsy/rasta/happy sub 3 yrs an counting ✊🏽🤗
Nice! I bought 2 of these. Then watched your video. Then cancelled my order and bought 2 more with your discount code and saved $100! Hope to use one as a UPS system for my internet. And the second as emergency power in case of a blackout.
Very nice review! I swear man, Jackery is giving everybody but the pizza delivery boy a Jackery in order to get reviews! :-) But of all the reviews I have watched, you provided the most usable information! Thanks!
Ah man, you are very smart man. And thank you. Jackery had a $20 dollar coupon on Amazon, then I used your code and landed a jackery for $200.11 all in with tax included. Thank you!
Yea i see that low low price deal.thinking of getting it to supplement my 300wh clone brand I have.this could be enough to get me by and keep me from spending $600 to $1000.
Love my Jackery 440 as a backup power for my CPAP machine. The 440 is the big brother to the 240 shown in this video. Pros: Better than a gasoline generator. * Powers my CPAP machine for 20 to 24 hours or the first two to three nights of a natural disaster. * Provides nice clean PURE SINE WAVE invertered electricity for expensive electronics. * No power fluctuations associated with gas generators. * No noise. * No fumes. * Everything including the inverter is in one easy to carry case with easy access USB, DC and AC outlets. * Easily fits behinds the passenger seat in my car. * When not in use, holds a charge for months. So it only needs to be checked monthly. Cons: * It does take 8 hours to recharge, but I think most batteries at this price level do. For me, $500 is well worth the money to know my CPAP machine has clean power for at least the first two nights of a power outage / natural disaster without running a gasoline generator outside my house or car. Expectations: It does NOT run a regular microwave or refrigerator. Batteries that run kitchen appliances, like the ones we see in sailboats and luxury RV's, cost thousands of dollars. SV Delos has one of the best battery setups I have seen on RU-vid. They live full time on a sailboat, so for them, it is worth the extra money. ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-GvDCLtN22jY.html
Tom, Well we watched your video on the Jackery. Instead of going through my normal routine of "researching" a product, I followed your lead and saved myself countless hours. That being said, I went on your Amazon product page and ordered one. So not only did I get the $15.00 coupon and the HOBOTECH coupon code discount, we set you up with a bonus too for your work. To top that off I used Amazon Prime and it arrived in less than a day. KeepOnHoboTech'in
First, congratulations on your ever climbing subscriptions. Hobo_Tech certainly personifies what you know and how you deliver presentations. Your expertise and experience provides a comprehensive delivery. You are probably the best candidate/RU-vidr to provide product reviews and endorsements. Great job and thanks for the input.
I love that you have a great understanding of all the electrical things. This is me now after trying so hard to understand myself🤪🙃😳. I want to get out there, and live a nomadic life, I’m just so lost with understanding batteries, amps, volts, watts, inverters, achhh!🙀
Just received this yesterday (June 11, 2019) as part of an Amazon Lightning Sale. Jackery has made a couple of minor changes from when the video was made. There were no two boxes labeled 1 and 2. Instead, the charger and 12 charge cable came packed inside the black zip pouch. That looks to be a good idea reducing packing cost and waste. The cables look the same. The other change is the display layout is rearranged. The battery state of charge icon is the same and the input power still shows in the upper left corner to the left of the battery icon. The output power now shows on the left side of the battery icon under the input number. The remaining battery percent that was in the lower left corner is now centered on the right side of the battery icon. The new layout may be slightly easier to read. I do not know if there are any other internal changes that can not be seen. It came 33% charged and it easily charged right up to 100% overnight. Right now I have a 4 battery AA charger plugged into the inverter and all is working well. (The AA charger is drawing about 10 watts.) Looks like it is going to be a good and versatile portable power source. I think Tom's review gives a great overview of the product!
One thing I love about those portable power sources is that, they’re getting smaller & smaller in size! My dad has this old Duracell portable power station, and its a big boy - takes up a lot of space in his work van! Cheers Tommy 🖖🏼👌👍😎✌🏻
I have the same exact unit and love it! I filled the 12 volt hole with a 12 volt plug that contained two USB ports giving me four USB ports :-) I'll look forward to your cabling video on how to hook up a solar panel to the jackery. I've already got a 50 watt panel, hoping to use it!
I own the 240 and 500. We are avid hikers, campers, and travel alot. THE 240 and my opinions..... Just perfect for the carry weight to camp, beach, or hanging outside the RV. I use ours to recharge my phones, laptops, 18650/21700 and various eneloop batteries. Also I use it for my camplight, just anything you can think of without lugging alot of unnecessary weight making charging simple and quick. I use my 500 for more of a longggg term usage away from AC plug in power. So in short the 240 is just light and simple......for the price (if you can afford it or now the 300 model) why not buy it. Save the500's & 1000's for the heavy long term work. I bought the Solar package with the panels for all my models.
Not bad , but like you said 7 hour recharge . So if i don't have solar i'm gonna need to run the genny so i may as well just charge everything i need ? Looking into solar for the RV .
The good this is I’m getting this for a festival to use string lights and a small usb fan during the night. So I could put the solar panel in my windshield during the day to charge.
I appreciate all the information. That was a great review. Would to and will search some of your previous SOLAR information. I really need to learn more. Thanks
Thank you for your review. I have been very seriously considering purchasing the 240 just to have as backup if the power goes out, or to use wherever I don't have readily available power. I think I'm going to buy it.
if you have a CPAP that uses a humidfier and heated hose it will drain in about 4 hours. If you turn those off then you can get all night. But if purchase a DC inverter because the Airsense 10 uses 24 volt. The inverter takes the 12v and boosts it to 24V a good purchase
I noticed that Jackery has supplied several nomads with this unit and overall have rated this unit as pretty good, and the only one I've seen that has the 440 as well as the 240 also the mini solar panel, is Vancity Vanlife and also rates it as pretty good, I guess it wouldn't be a bad investment if you can get one that is on sale....thanks and take care HT.
They look pretty handy and in your closing remarks you mentioned your e-bike battery charging preference which is to "charge it slow so it lasts longer", I rather suspect that may be there reasoning for it having a long charge time. That was a good review that will definitely help people and assist them in their buying decisions!
It's possible. Seeing they offer a 2 year warranty. Still, I'd rather have 1 year warranty and be able to charge in 3 hours like every other device I have.
Your videos are the reason I just ordered the Jackery 500 with the 100 watt solar panel as well. I will be getting all the Jackery models over 500 ah.. Definitely the best I can find for the price range. Please tell me if you have any other Solar Generators that you can recommend over the Jackery 500 at this price point.
Solid, fair review... yeah, what is up with max charge input? It's larger on the 440 - 100w - but still the same issue. If they would double those max inputs, these would be in another league vs the direct competition... real head scratcher. Thumbs-up for the review and your cool cat!
Hi again :), We have a AER Amplifier- it says Ac 50/60 - 270 W on the back. From testing it on a watt tester, It fluctuates from 20w to 120w Max (at high volume) would this work ok with the higher label on the rear? Also would it safe to plug an extension lead into the Jackery 240 with say 4 plugs -using 20 w each? Thanks
I think your reviews right on I love my jetpack and just today my sportsman generator arrived home depot dropped the price just like you said how about a update on your sportsman? The drone seans on your last video were awesome that will be a cool asset for future videos keep up the excellent content thanks again!!
Nice review man. I don't need one but it's pretty damn cool. Might have to make up some reason for one for sure! The 2 cons aren't that bad at all (not a paid spokesperson). I don't need more things beeping at me needing my immediate attention. I can read so that wouldn't be a problem to me. Also, charge it while you work.
Do you think that the Jackery 240 or maybe 300 can run a portable air conditioner (e.g., 10,000 BTU) for at least for as long as the battery lasts? 🤔 Thank you.
I don't why they specify a 42 Watt limit. The charger is a constant current (about 3.6 Amps) from 11.25 volts to 25.5 volts. I use a 24 Vdc AC/DC power brick (purchased on eBay) and get 77 Watts of charge. From AC power, I get a full charge (from 0%) in about 4 hours. For DC charging, I use a boost converter (also bought on eBay). 10-30 Volts in with the output set at 25 volts. Using a 120 Watt, 12 volt solar panel, I get 82 Watts of input power and a full charge in the Jackery 240 in about 3.5 hours.
You should reach out to Inergy Solar (Pocotello, ID) and see if they'd let you try out a Kodiak! IMHO, they're the best option out there, especially when compared to Goal Zero's newer li-ion offerings. Different price point, but don't think you'd have any complaints with it, especially the recharging time part.
Not sure what small appliances you're referring to. I watched another video where he tried an electric kettle (no go), a toaster (no go) and a hair dryer (no go) and an ac fan (no go). It wouldn't power any of those at all.
Hey Hobotech! I just found your channel as I begin researching solar. I want to run a 10w water pump in a hydroponic tower that I 3d printed. I contacted jackery and asked if it would work for my application and the detailed response i received said "yes." I was hoping you had some input n this kind of setup; basically a single 100w panel, with the jackery 240 in an enclosure. The thought process is that I have mobile power constantly supplied to the pump with using only two compoenents, the panel and the jackery. In your experience, will this unit perform 4-5 months out of the year being constantly run? Thanks Hobotech, you rock!
Thank You for this comprehensive review! Well, from what I've learned from your vid and investigating more on-line this unit cannot power a desktop, correct? I was considering getting this in case the power runs out for a few hours. However, I suppose I could buy this unit and charge my Iphone and save the money for a more expensive model, correct?
The only difference is battery size. If you really wanted to spend that much for a larger battery the 440 would be a better deal since it can be charged a lot faster at 100 watts.
I just got a JACKERY 240 the paperwork said I can use a generator to charge it so can I use any generator to do this? And what's the smallest and biggest I can use. Thanks bro..👍
Thank you for the knowledge! Now.. I know the Jackery CAN be charged while charging other devices, but is it a good idea? TX power outage survivor great freeze of 21 looking to I.prove his power options with only enough cash to do.it once... Thanks in advance.
18 W, charging for cell phone is not a lot my second generation iPhone SE will charge and 18 W and my other coworkers phone that’s newer will charge at 20 or more watts but yeah, of course 10 W is better than 5 W
I bought a jackery 240 about 3 weeks ago and I've noticed something that I may just be overthinking about, and I'm trying to get other owners of the 240's opinion. I've noticed that when watching videos here on RU-vid that on some units, even like the 500 and 300 when you plug in charger to charge that the light is blue when charging and turns green when done. I've never saw a detailed video on the 240 to see if it acts the same when its done charging. Mine never turns green. It will charge up to 100% and the watts will taper down, slowly going to zero and the charger box even gets cold, from not pushing out anymore power, but the light never turns green, it always stays blue. The unit seems to function fine, and I even left it plugged up for like 12 hours just to make sure, but it never changes to green, it stays blue. Can anyone else who owns a 240 confirm if theirs stays blue or does turn green? Like I say, any other time I wouldn't think anything of it, but it's got me questioning why the 240 stays blue but the other units turn green when done
Hey Tom. I have a question I got a 240 from your store and I ant find the vid I think you said you can charge it with 100 w panel but you. Ant use more than 60 watts. Double cking doesn't error out or does just waist the "40" watts. Asking for cloudy days. Can I get more out of 100 watt panel on a cloudy day? It's only $20.00 more on a ridged panel. I DONT WANT ERROR OUT or hurt it in the sun.
Great review,i want to buy this,i have a question if its possible to answer my friend as i am not an expert on electricity....i have a solar panek of maximum power 250Wp voltage at Pmax 51,2v and current at Pmax 4,88A maximum system voltage 1000v.....is this suitable for charging the jackery without harming it?i mean with the typical mc4 cnnection to dc would work right?thank again
Hi Tom, great review, it's a shame it's not made in the US, is it better to have cheap or quality? Here in the UK, look on the back, made in China, even apple I phone's, safe travels 😀🇬🇧
I got a 13 inch 2012 Mac Book Pro that uses a 60 watt charger (Mag Safe Port). Instead of using the Jackery inverter (DC-AC-DC) it would be nice to use its cigarette lighter instead. You mentioned you do this for a PC, DC-DC (I don't think you provided the link). Do you know of an adapter that could do the same for my MPB who's charger outputs 16.5 volts * 3.65 amps = 60.225 watts? And the ability to connect a Mag Safe Connection?
I have the Jackery 240 and solar saga 60. When using the solar Saga 60 I get between 45w and 55W. I do live at around 8000 ft above sea level. When I bought it every review out there said that all charging is capped at 40w, which is what 12v and ac charging gives you. It was nice to find out after using it solar charging is not capped at 40w. At 55w it charges in about 4hrs.
This is no shocker. The SolarSaga 60 has a very high voltage for its size - the highest I ever tested. I demonstrated in later videos it will charge in the low 50w range if you push 25+ volts into it.
Tom it has been a while since your review. Have you found a way to charge at a faster rate or found another similarly priced product which charges at a faster rate? While on the topic of charge rates have you found USB battery packs which charge at higher rates? It would be great for a nomad to be able to charge their USB batteries and portable power stations while spending 1 or 2 hours in a Starbucks or library. Also have you found plastic plugs for the Jackery 12V plug? I have several 12V adapters which each provide 2 USB ports and 3 switched 12V outlets. Like the Jackery no plastic plugs were included.
The Jackery 240 is limited to 42 watts no matter what you connect it to. Sure, there are other units that charge faster but they aren't built as well. Most USB batteries will charge in 2-3 hours. I have Anker brand units shows on hobotech.tv/amazon. Getting my hands on a Jackery Bolt soon.
Hobotech - I want you to take a look at my youtube of my use of the Jackery 240 I bought with your code and how I am using it with my Thunderbolt solar panels from Harbor Freight. I just have two videos as of now on youtube (thanks to my grandson). You can search Senior Man in a Van. Thanks again. I use it all the time.
