DoSHIn 20000mah Solar Charger Dual USB Solar Power Bank with LED Light for iPhone 6 Plus,iPod, Samsung Galaxy S6 and More (Red)

Not a 20,000 milliamp...Only charges my Galaxy S9 2 times...would not recommend if you are looking for a 20,000 milliamp. It is more like a 10,000 milliamp charger...

It is nowhere near the 20,000 mah advertised. At most it is 4,000 mah. The case is cheap and the solar panel pushes into the casing with a minimal amount of pressure. Its only redeeming quality is the LED flashlight, which is slightly brighter than an iPhone camera flashlight.

I like it

works great charges 3 or 4 times with out rechargeing

It works good I love it

Horrible does not work.

Yes, I have one of those, but I should have known, that if it sounds too good to be true, it most likely is. Mine stopped working after a few charges and since there was nothing to be gained any more, I opened it up. Come to find out the description is a clear bait and switch or in other words a lie. As you can see from the picture. there are two batteries as the one in the picture in this unit. And this battery states rather clearly, 4000mAh. 2 x 4000mAh last time I checked does not come up to the stated 20000mAh.So, in the meantime I have disassembled the no longer working unit that I got. There are in fact 2x4000mAh Li-Po cells in this battery pack. I have them right in front of me. As far as the solar cell goes: The Solar cell that is included is a better joke. The solar cell included is a 107x61mm cell with 5V and 200mA or 1W maximum output. So, even if you would be able to get this at the optimal angle it would take the included solar cell about 4000x2 = 8000mAh, divided by 200mA => 40 hours of charging. Now in reality, the charging current will be 50% of the max current at best, and in solar technology one usually uses about 30% as the basis of a calculation, but even at 50% (best case) the battery would take more than 80 hours of extreme bright sun light to be charged. or in other words, 10 days out in the sun. And that is at the real capacity of 8000mAh. If this unit would have really the advertised 20000mAh, then it would take a month to charge from solar. You do the math if that is useful.

Works great

Mi è arrivato con consegna molto veloce ma il prodotto non è quel che dicono che sia. Non dura niente la batteria e il pannello solare è fragilissimo. Arrivato con custodia da cinesi senza istruzioni ne garanzie. Andate sulle marche conosciute e pagatelo anche un po di più ma non fate l'errore che ho fatto io a comprarlo.

Non posso giudicare il prodotto come carica batteria o dal punto di vista dell'energia solare perché non è stato provato.Appena arrivato aprendo lo sportellino delle porte usb, lo sportellino mo è rimasto in mano, la qualità del materiale era piuttosto scadente, nessuna istruzione all'interno ed era impossibile individuare la porta da 2 A e quella da 1A.Ho rifiutato il prodotto inviandolo indietro.

Non so se lo sto usando correttamente. Unico bottone da accensione per vedere carice residua e torcia a seconda dei click. Quando attacco un dispositivo comincia la ricarica con luci led blu ma dopo qualche minuto si spegne e la ricarica non avviene più. All' accendere la torcia e ricaricare il cel o altro dispositivo bt allora si rimane attivo. E' normale?
