This panel can put out close to 100 watts ru-vid.comUgkxOqI2yqX0XVrhR2BMJciTWrHJpG8FhJyg when positioned in the appropriate southernly direction, tilted to the optimal angle for your latitude/date, and connected to a higher capacity device than a 500. The built in kickstand angle is a fixed at 50 degrees. Up to 20% more power can be output by selecting the actual date and latitude optimal angle.The 500 will only input 3.5A maximum at 18 volts for 63 watts. Some of the excess power from the panel can be fed into a USB battery bank, charged directly from the panel while also charging a 500. This will allow you to harvest as much as 63 + 15 = 78 watts.If this panel is used to charge a larger device, such as the power station, then its full output potential can be realized.
As a vagabond I'll say solar panel charges are actually very useful for specific types of lifestyles. Yes the solar panel method takes a very long time to charge, but if you're like me and walk 10+miles a day or you're camping, even homeless. You don't need it to be max charged, just enough to either keep your phone from dying or enough to turn it on long enough for an emergency call etc. If you keep it out enough you can probably maintain around 30% of its max charge just walking around. Enough to last you till you can get to a plug or enough to charge. Phone to like 15%>
I live in one of the most sunny places in the United States, we never see rain or clouds here. I left this outside for weeks, maybe a month, and it still was not fully charged. But it was pretty close, I was able to charge my iPhone and some of an iPad with it.
@@bingcherry1122 waiting an entire month for a battery to charge is impatient? For those of us with an actual life, we need to charge our electronics DAILY not monthly. Why are you here? Do you even use electricity? Lol!
Someone opened one of these up and posted a photo in the Amazon reviews on 12/19/20. It showed a 4,000 mAh battery inside rated at 3.7VDC (not at 5VDC specified) for a total of 14.8 Wh (20,000 mAh @ 5VDC = 100 Wh). This would be only a fraction of the advertised capacity. Does anyone know what the real capacity of this charger is?
This is very common with the power bank market. You never get what you pay for. My advice is only buy 10k max mAh banks they are under 20$ and usually true to capacity.
for me, simply have 2 cheap 10000mAh powerbank is way better than having an expensive 20000mah powerbank, portable, cheap and never feeling too bad to throw it away, if you buy it from malls you can have 1 year warranty and easy to replace for free if error happens
That's why we do product research. There are solar power banks out there that charge up to 400mah. With that said you did an amazing job reviewing the product.
This is way better than other solar power bank videos. Concise and to the point. I would rather go for something that has a selling point such as cold resistance for alpine excursions. Thanks Tava!
Oh man the solar is useless. Sitting here in the hospital with thing drained as well as my cell phone thinking in a couple hours it'll have some kind of juice to pull. It is not an alternative.
ummm....glass cuts the power a solar panel gets by like 70 percent. To our eyes, windows let all the light through, but realistically glass reflects a lot of the light.
What you can do is if you bought one of these products and think its a waste of money, you could just buy the folding 5 panels that have a micro usb input and charge it that way. It's own panel will pitch in 200 milliamp hours and the 5 other panels will pitch in about an amp.
@@gary7vn This is true, but some people unless they look at the manual it's misleading because one panel simply doesn't provide enough power these days.
dude honestly, you probably only get (close to) 200 mAh if it's very sunny, in direct sunlight, with both axis angles constantly aligned with the sun, And even then it's only getting that around maybe 10/11am til 2 or 3pm most. With the peak times of the curve being close to 12 pm for only a couple hours. Plus DEFINITELY DO NOT EVERRR leave a lithium ion battery sitting in direct sunlight!! I don't care what any manufacturer or techy tells you. Because reality and physics would disagree 😂 But seriously, they are literal ticking timebombs if left in the sun especially with the solar panel being black absorbing the most heat from the sun, and it sits directly on top of the battery cell or cells inside the case, which is very tightly packed with no fans or air flow. Just saying. Do what u want but it's your funeral. Where i live in the South it gets deadly hot. Lithium fires in these batteries set in the sun long enough (just a few hours) can combust extremely suddenly without warning and burn extremely hot and fast burning through anything they're sitting on that isn't like rocks or brick or something. Cars have caught fire in less than 30 mins from a battery sitting on the dashboard or seat in direct sunlight.. But anyways if safely used, They really are in my opinion possibly useful if you just always have it charging in the sun after a full charge on wall outlet, and don't rely on it but keep it around. Then if you do run out of power and really need it, and it too runs dead, at least you can get a tiny charge into a device to power it up in an emergency. That's basically the bottom line. If i have one of these, the solar panel is literally useless for daily use so therby making the whole idea pointess. But if i am stuck somewhere, even not an emergency, maybe i go to the State Park, and hike in a couple miles, and my phone is dying, plus the little solar charger is dead, - while i'm hanging out enjoying the nature or whatever, maybe i'm cooking some food and my phone dies, i can be getting some power at least, even a tiny 4 or 5% on my phone where there was absolutely none at all if i really needed to check the weather right then, or the time, make a quick call or look up something very important, etc. So i guess its cool if you think of it that way. But even then, the solar panel still is so pointless since you can get quality solar chargers that put out 1.2 and 2.1 even usb3 now, with quick charge that are cheap, durable, lightweight, feature rich, waterproof, very price competitive, and actually charge your stuff in a few hours. lol
You exactly look like one of my friends. You also have the same last name. Do you perchance have relatives in Germany? Edit: I’ve looked through your other videos, and you even have the same hobbies. I think I found your doppelgänger / long lost twin…
I have a 20,000 mAh cellphone charger too. But, the number was a lie. I fully charged the battery up ,then plugged in a meter and then a Usb desk lamp and let it run till it was empty. All I actually got out was 3474 mAh at 5V DC. So, you might want to dig a little deeper and see what your device REALLY can store AND deliver to your devices. Honest manufacturers will tell you the real number: NightCore 10,000 mAH Battery charger "brick" says right on the side it will actually deliver 6400 mAh at 5V DC and it is a top-of-the-line device ($ 60 new)
I bought a solar panel battery like this with 4 panels that folded out. Kept it on my dash to charge while I rode my bike on a trip. I came back to a swollen battery. This is how I found out that the batteries themselves cannot take heat. Since the solar panel is required to be in the sun (and heat), having the battery attached (and also in the heat) is not a good idea. You need the solar panel and charger to be separate in order to keep the solar panel in the sun and the battery in the shade.
Same. Left mine on the car dash a whole summer and thought nothing of it until it hit one of our hottest weeks. I came back to a fat battery and panicked thinking it could explode at any moment. So even if you could efficiently charge through the built in solar panel powerbank, you run the risk of overheating the battery to even charge it. These solar banks only do well to capture short periods of light which will take weeks to charge safely.
Wow finally someone said it like it is, the solar on these sucks. I really don’t need mega milliamperes. I would really like to see a 10 or 15 k mil with a solar that actually works & is capable of charging the unit.
Yeah.. I have the 36800mAH version and it only charges my phone twice! Clearly it has less juice than advertised. Looking into the product more closely you can find lots of contradictions and false claims with their advertising.
Thank you for the update on the solor device. So, which solar power charger do you think is the best to purchase that charges fast buy the sun and is not a gimmick??
Basically there are none in this form factor and type that aren’t a gimmick. The foldable solar panel chargers are the only ones that would actually work well.
I used mine for the first time this past weekend, but it didn't seem to work. When I plugged the USB cable into the charger, I did not see any indication on my phone that it was charging from the solar charger. What's up with that?
The only thing I don’t like is…. > “IF” ☝🏾☝🏾🤦🏾♂️😡🤦🏾♂️🧔🏾♂️🤦🏾♂️🤷🏾♂️ if this battery bank dies,… “The solar-part of the device… 😐 😑😡🤦🏾♂️👎🏾 does NOT work. I thought that solar was a back-up or a just-in-case” ? Such as if your battery bank dies, then the solar would be able to kick-in and charge my phone. If I’m reading it wrong, then please educate me. Because if the solar works only if the battery is a little-charged, then I’ll be sending this 💩 back!! Immediately!!
Great review, very accurate! Unfortunately, I saw it after making the purchase. We are dealing with a power outage so I got it thinking I would use it for my device (as advertised) and outdoor solar lights which cover my two of my needs. It worked the first day for a few minutes and it hasn’t charged my phone since. I will be returning it and looking into a better quality charger. Thank for sharing!
I never thought that the panel on my charger would recharge it in hours, and I don't recall any advertising that ever said that. What it is good for is as the proverbial emergency back up in case all else fails. A few hours in sun should give you enough juice to charge a phone enough to make a short call or to note your position via the GPS.
Mine’s just flashing those two lights and not charging any batteries! Impossible to turn them off, hopefully it will stop flashing once the battery is completely flat.
NEVER BUY this!!! its a scam, batt size only ±2300mah, dunno as u recharge it many times it will reduce the batt quality. i buy 3months ago around 8USD. only the 9 SMD works best. works best only when charged at home wall plug.
How to fully activate solar cell battery? 1. In order to fully activate the battery, please charge it via outlet or computer for 10 hours at least at the first 2-3 uses 2. For safety, DO NOT leave the solar cell power bank charging in car in case of high temperature and avoid crashing.
I got one offered as a minor job perk, and with the Irish weather, the battery drain is stronger than any solar charging I was able to get. Pure marketing gimmick.
Does the battery stay on ready to charge a phone? Or if a phone reaches 100%, does the power bank shut off, and let the phone go flat, despite the power bank being able to charge the phone. Basically I want a power bank to act like an extended battery, not just to charge the battery when the bank is turned on. Does this make sure phone battery doesn't go flat if plugged in?
Wait, a Solar charger NEEDS to BE charged FROM something else? Or 4 days (in Fla thats not a prob)(My "adventures" are after hurricanes- no electricity) Seems to have missed the point of being- really really solar right? I only have- common sense.You were very clear, better than the other guys doing these.
Thanks for the video, it was really helpful! Do you know the temperature range, as a charger/powerbank, for normal operation? Because some equivalent products don't work well for low temperatures (0 or less ºC) and/or high humidity environments. Thanks in advance!
I am not entirely sure, but since this battery isn’t special from other batteries, I would say it would start to drop performance below 0°C and over 45. As for humidity, it is said to be waterproof, so I doubt that would have very much impact on performance.
I have one, the solar will only charge it to two bars. After I fully charge it from the charger, it won’t even charge my phone past 30% before it dies.
If you were stranded on an a deserted island like Gilligan you would have years of time to work with. In that situation the solar panel would be very helpful!!!! Lol!!!!🤣🤣🤣
These only hold about 4000-5000mAh. They're falsely advertised. Just get a well recognized brand one or get one at best buy. Most of the amazon ones are chinese brand that are nowhere near as good as advertised.
Even when you plug it in it takes forever to charge lmao. Ive had it plugged in for 12 pluss hours and i have 2 bars 🤣. I got it on amazon so i assumed it was a dud
It's fake bad device I do have one and three days out in the sun will still link one the first blue blinking light , extreme bad the only way is electric connect , for an hour or more to full charge
I had one of these I went on a plane to China and it was taken out of my bag never got it back, I portable charger that you can't travel with 🤣 that is an oxymoron
This was very informative, and help a bit woth me deciding if I should go with a normal power bank vs a solar power one. Really a awesome job on this video.
Thank you! In Germany it'S Oktober right now and the Bright Sunny days are now replaced by more greyish days. Is it useless? Does it need real Sun...or just daylight?
Good video, and informative, but , once the device is charged from a wall outlet, wouldn't keeping it in the sun, while hiking assist on keeping it charged, even at a lower clip. I love anyone's input. Thanks
I have this and I've barely used it over the course of one year because it only charges my phone for 5 minutes and the lights are flashing and won't turn off no matter how many times I click the button. It's useless
@@tavakessler yeah haha it worked great until it didn’t! If I can figure out how to get the lights to turn off I’ll still keep it as a charger 🤞🏼 I came here to make sure I wasn’t doing something wrong, so thanks for the vid :)
3 rules here. 1, buy from a reputable company. These solar chargers are stuffed with fake batteries with heavily skewed mah ratings and have been known to catch fire. 2, solar sucks. You need to be drawing at least 2 watts to 5 watts to make any real use of it and charging a 10,000mah power bank takes about 5 days of uninterrupted Sun to work. 3, buy a high capacity powerbank from a good company and get a separate solar panel. A good combination is the ROMOSS 60,000 and the Tenergy 60watt solar panel. It will charge a massive powerbank in about 2 days with a type C charger and can be a backup battery for laptops NOT consuming over 22watts of power. The only thing I don't like about ROMOSS power banks is that for the first 3 uses they need to be fully charged and depleted to get an accurate % reading and the size is a bit bulky, like a plastic brick lol.
