Does the solar panel work though?

can you charge it through a pc?

I bought a power bank with exactly the same case but orange from AliExpress. They said it was 5v/2.1A and 20000mAh but it couldn’t get higher than 0.50a and it is approx 6000mAh i opened a dispute and got full refund and i didn’t need to send it back lol

Make it yourself thanks to Avasva solutions. I think it’s the best way to learn how to build it in the cheapest way.

300,000 Not a chance. You would be lucky to get 5,000 out of it.

Agree that 300,000mAh is impossible but even 8,000 is useful. I have a quality 7,500 mAh backup and it’s wonderful. I have a small 200mAh power supply I use with my phone. Sometimes it can’t keep up with bright video playing. So figure your phone averages around 100mAh. You can see the solar panel is almost useless considering ~5 PeakEq hrs per day. Consider it’s 10,000Ah backup with light and solar panel that will provide 25% of your power. Charge overnight with 1amp. Maybe this specific unit is lower quality than others. Mine is still arriving. …I’ll update later.

What’s written on the battery (probably more accurate than the seller’s rated claim) is the ‘theoretical maximum’. And since the rated output is 5v, with these being 3.7v batteries, that means they’re wired in series, giving you 7.4v at 4000mah. The regulator on the electronics board, through heat loss and inefficiency, will stop the voltage down to 5v.

But the CAPACITY is still only 4000mah – in other words, maybe 1.5x to 2x the battery in your phone. Remember, your PHONE already uses some of the best battery technology available – the phone manufacturers want to be able to claim great battery life. Why would anyone expect that two batteries, about the size of the one in their phone, would be 50 to 100 times the capacity?

This is a 4,000mah (at best) battery bank. To claim it’s a 300,000mah bank is criminal.

I bought 2, each holding 500,000mah. I love mine! you can charge the unit by sunlight or pc, mines not fake, will come in handy when the power goes out! i may just buy some more.

Saw something like this on Ebay, I happen to have a 160Ah deep cycle battery on hand, it weighs more than 10 kilograms. What they are advertising is 300Ah in a tiny little device like that, they are absolutely full of shit. I also have a 15Ah battery that weighs about the same as a brick.

Do you think the only way of getting a 30,000mah power bank is to make one yourself?

I can’t stop laughing on this video I would crash to bits lol

ça rentrerait une 3ème batterie dedans ?????

its fake

I bought this power bank and it is absolutely a piece of crap. Never charges using solar power, then I thought, I may be that it charges directly my phone when I put it in the sun…I was wrong again. It only charges when using a power outlet and it has enough power to charge 2 iPhones, 3 at the most. Don’t waste your money and buy a better one.
Thank you for this video. I bought the power bank before I watch your video and it was late late late late late for me 🙁

thanks for the review

Three hundred thousand!?!?

Fck me..I just purchased this on ebay and waiting for delivery..I paid 15 bucks. I hope ididnt get fcked to bad

I bet Chinese laughing over this video smart taken your money but good thing you open it too see much big ripp off buy this power bank thanks for making this video save alot money for people out there

I got this exact solar charger and it works great. Charged it via the supplied USB cable and a power adapter overnight.
I let my Samsung phone run down to 20% and plugged it into the solar charger. I timed it and it took 1.5 hours to fully charge my phone. I used my phone like I normally do; let run down to 40%. I timed it at 8.5 hours. Plugged the phone into the solar charger again. I had not charged the solar charger. I timed it again and it took 1.5 hours to fully charge my phone again.
I recommend this solar charger.

god i can’t believe it;
