Solar Qi Power Bank | Blavor 20,000 mAh Solar Power Bank 

Have you ever used a solar power bank? How about Qi charging? Lemme know!

Thanks for the review. I did some actual testing of the solar capacity, and here's what I came up with. The specs for this unit say "Solar Panel Output: 260mA * 5" which is a meaningless number. Amperage without a corresponding voltage tells us nothing about the power. That is why solar panels are rated in watts (which is amperage times voltage), which is how they should have stated the solar panel in the specs. So we can't determine anything at all from the info they have provided in the specs. Since the panels can be removed from this unit, it is very easy to measure their output exactly. In direct sunlight, facing the sun, in the morning and at winter solstice (so worst-case for direct sunlight here) I got a short circuit amperage of 0.66 at 6.8 volts. Multiply those together to get a maximum best-case of 4.5 watts of power. That is just for the four external panels. Divide that by 4 and we find that each panel produces 1.12 watts individually. Multiply that by 5 (for the 5 panels total) and we get 5.6 watts. So the total solar power of all the panels is 5.6 watts, which is actually quite good for its size (just by looking at them you can tell they are good monocrystalline panels). Based on other solar panels I have tested and their specs, this is right in line with what is expected. Now we can calculate the amperage at a specific voltage. Since USB is 5 volts, if we divide 5.6 watts by 5 volts we get 1.12 amps (aka 1120 mA). Thus, theoretically at no loss, the solar provides 1120 mA of charging for a 5 V USB device. In reality, I would guess 900-1000 mA of actual charging maximum after losses. After some more math, 20,000 mAh divided by 1000 mA gives us a charge time of 20 hours in direct sunlight to totally charge the back if it were empty. That is with the panels directly facing the sun. If you have the panels laying flat on the ground, it will reduce the wattage significantly. In my test I also measured the amperage with them laying perfectly flat. It dropped from 0.66 amps to 0.18 amps! That's reducing the power to less than 1/3 the normal. So it is critical that the panels be aimed at the sun for maximum charging (and that means moving them throughout the day to follow the sun).

The only decent review of this product I’ve found anywhere - hugely appreciated!

Great review and great presentation. Just one constructive criticism...when talking about battery storage, always say milliamp hour...milliamp is a measure of current; so when you said "each panel is 260 milliamp hour rated" you should just say "260 milliamps" as that is the max current output in full sun (1.3 amps with all 5 panels connected). And at 1:09 you said "it's a 20,000 milliamp power bank", there you should say 20,000 milliamp hour power bank. I know this is nit-picking but as an engineer I just had to mention it.

I’ve been reviewing solar banks for a while and your review helped me more than others. I just ordered a Blavor 5 panel solar bank.

You answered all my questions so thank you 😊

Just got mine yesterday based off your review. So far so good.

Hi peeps, bought this guy for my upcoming Inca Trail at the end of the year. I will keep commenting on this post as I test all of the functionality. Here are my observations so far: - I couldn't even get one extra bar (out of 4) of charge during a 4 hour drive in the Australian sun while it was on my dash. I since found out that having glass between a solar cell and the sun reduces the efficiency SIGNIFICANTLY. So if you are thinking of this as a feature, don't, outdoors direct sun only. I will test this soon. - The bad boy is tubby, I guess it is as expected out of a 20000 mAH (cough 13000, more on that later) power bank - I fully emptied it, and now finished fully charged it, to test exactly how many mAH of charge I can get out of it. during this, I calculated that it took 10 hours give or take 5 minutes to charge from nothing to full using a 5V/2.1 output charger. - The Qi charging works well, not great, but well enough to make you smile, with my iPhone XR. Next up is the mAH calcs. Hope this helps :)

Detailed product review, thanks for sharing, opt in

solid review, very thorough.

Trust me ladies and gentlemen, when you whip one of these chargers out of your purse/pocket, you will start attracting the right kind of people. ☺️

Found it.. Thank you

A suggestion, if I may? I like your unbiased reviews and this is not a criticism. Please, when you're speaking about the unit's specs, mention the input and output specs, voltage and amps,it is important when choosing a solar power bank. Other than that, your reviews are well done and informative. Thx bro.

This detailed video is really helpful...tnx alot

Liked and subscribed to your channel after watching this video

Anyone flew on a commercial airplane with one of these? Great review by the way I bought one because of this video.

How is this channel only has 700 subscribers?

More tests. Example test the TRUE capacity since many are not what they claim, also test how much solar is captured in an hour. Stuff like that. Great potential.

Where do you hook the compass lanyard clip to , is it to be placed on the little clip that they say is the "hanger "

I just ordered one not too long ago...not from blavor...but it has 5 extra solar panels and qi wireless...same one different company....anyway...this so far is so much better then my previous solar charger.(it only had 1 solar panel and kept turnin off and on)...but with the new one..it charged my phone atleast 2 times..i can probably charge several times more but no need for it lol..but if you have an external solar charger pad...even better

"I got enough QI for the whole Valley, Grasshopper."

Very handy

It's strange that most of the Solar charger power bank reviews I have seen on RU-vid are indoors and rarely have actual testing these devices (with a USB voltage tester) outdoors in bright sunlight.

Great video! I just received this exact model from Amazon. Did you experience any difficulty with the Qi charging? I am curious if I need to do something to the power bank to enable or begin this function. I have tried while the power bank is plugged in and charging and I have tried while the power bank is in direct sunlight with all panels charging and still no response from the Qi charger. I have not been able to find any discussions online addressing this problem so my guess is that I received a defective model. Any help would be greatly appreciated. Thanks!

what about a test, about how much it acqually need to charge itselv with sun?

Ours just stopped! What do we have to do we r camping now all the time and it won't turn on at all do we have to change the fuse and If so what fuse amp do we buy?

Hello JDubb. I purchased on of these this week. Quick question, what is the best way to attach it to my backpack in order to charge on a hike? The plastic clip that pulls out doesn't seem adequate to support the weight with solar panels attached. I worry that it will break. Do you know of gadget that will allow this to easily attach to a backpack? Thanks. Dan.

FINAL THOUGHTS You can find the final results and tests that I carried out on other comments below. Far from professional tests but I think they paint a great picture. 1 - This power bank has a "Rated capacity" sticker on the back of the box stating 13000 mAH. this is NOT a 20000 mAH power bank. 2 - The power bank CANNOT handle charging multiple devices for it's whole charge. Really struggles. 3 - The power bank managed to 9233 mAH worth of charge into my products from full battery to empty. 4 - The solar charging cannot be efficient under glass. Direct sunlight only. And like so, takes roughly 18 hours to charge. I think those are the most important things for people to know before considering this product. I will be sending mine back. Hope my findings helped

Is the hook for the carabiner strong enough to hold the battery and the solar panels off of a backpack during a hike? I can't seem to spot it in the video.

@JDubb Which is better this one(in vid) or PD 18W Solar Panel Charger QC 3.0 Fast Charging Power Bank,Solar Phone Charger 20,000mAh Solar Powered External Battery with Camping Light/Compass Type C Portable Charger Three Outputs(Orange) ??

Can you add panels if you have a Balvor that is setup without that clip?

If you're a DIY they sell these multi panel solar chargers on ebay but withoit the Li Poly battery. Youll save a few bucks and you know whats in it.

Is it water/dust/shock proof like the other blaver products?

I think it's better than the other 20,000 Mah one since it isn't that much more expensive and i want it but i dont think i can get it in qatar

Does this have a fast wireless charging for Samsung S9, does it also charge macbook pro?

I own multiple power banks including solar so here's my $.02. First off output from the panels is in 100% direct sunlight at peak times of the day so don't expect full rated capacity. Second is don't think they will work well in indoor lighting, they won't. It's a maintainer at best.

Please let me know if this bank charges in the sun while charging another device at the same time. Thanks!

I am wondering 2 things about using this device. 1. I would like to use it for emergencies, so if I put it away fully charged for 3 years and pull it out, will it still have power in it to charge devices. 2. How long will the power bank last if I use it to power 1 device every day for let's say 2 years.

How many hours of full sun does it take to go from empty to full charge? If not Arizona or equivilant, I'm expecting several days worth of full sun (at least 70 hours +) as reasonable.

cool

Looks awesome but the plastic piece can it connect to the bank when the other panel's are not connected? I don't want to lose it. Thanks great review as always.

What about the fast charging compared to the other Blavor video you made?

If for some dumb reason I want to add extra solar panels but only have room to add 1 or 2 more, can I customize how many I can put? Or do i have to use all of them if I want extra panels? And how does this compare to the other Blavor solar power bank you reviewed that only has 1 panel?

I'm looking for something that I can put on the dash in my car to charge in casual//emergency use. Will it overheat?? Is it good?? I live in canada so the weather varies...

Does this charge iPhone 12 wirelessly? Also is it slower charging the phone than the other Blavor?

@ Plug & Play, is it water resistant?

Would this charge usb flashlights and walkie-talkies?

What's your take on sozo vs lit mobile vs blavor?

does it charge faster because it have extra solar panels?

So does it store the solar power in the power bank

IS THERE A 4 PANEL VER.?

Great video ! I have the X-DRAGON version of this power bank. But the solar panels are not removable, doesn't have a wireless charhing capabilities or a usb tipe C port. But after all the bases are present ; 5 solar panels and flash light.

Is it water proof?

how could one be sent to Australia?

Is this FAA compliant? Can I take it on a flight in the U.S.?

2 years later, I wonder if it still works?

Will this charge your cameras and or the Gopro Hero 7 blk?

Can u charge it to electricity outlet?

how fast do u think it would charge a note 10 plus?

Does this have fast charging?

This think doesn't have 20000mAh. It's 16000, and if you are lucky you will get only 14k. I've seen pics of someone who opened it up and it was only a 8000mAh battery, has 2 of them = 16k

Does that say "tepy-c"...?

You know, it would be ok to actually go outside, and test the solar part of the power bank. just a thought.

These packs are Way way TOO HEAVY FOR A PHONE ON A HIKE. Best you get a solar panel (no battery) and when you stop, then charge up your phone. All these "reviews" never test how the device charges a drained iPhone.. .. technically, this full charge can charge an iPhone XR like 6 times (20,000 mAh vs battery on iPhone XR 2,942 mAh)..but again, i get only 2/3 way charged... on multiple units.

852 Subs...Love your videos...like a million sub professional if you knw what I mean

is it waterproof?

Sooo, this or the Bigfoot?
