" ... This is a lightweight and powerful charger. ... If a cord can plug into USB for charging this will charge it up quickly as long as you have sun. ... "
" ... My balcony faces the south, so I've had this solar charger set up to charge power banks. ... One is an Anker 10,000 mAH I. I also have a Nectec 20,100 mAH power bank. ... Charging both power banks, when a cloud passes and the voltage drops, as soon as the sun is back, the voltage is right back up to .96 or thereabouts. ...

" ... Bought this for our camping trip and guess what this solar panel didn’t disappoint it charge my battery pack in 10 hrs with direct sunlight. ... "
" ... Also, I'll mention that it's better to charge a portable battery pack (I have a 10,000 mAH one and it's plenty for my needs) than to directly charge the phone itself. ... "
" ... Love this kepts out battery packs charged along with our phones!! ... Used it on my kayak in the sun all day fishing to charge our packs! ... "
" ... I liked the reviews I read about this particular solar panel, and I also liked that it did NOT have an integral battery of its own - I am hesitant to leave a sealed battery out in direct sunlight for several hours at a time. ... It took less than 2 hours to bring my 3rd generation Kindle from less than 10% to fully charged. ... I have also used it to top-off the charge on our turbidity meter, and the ion-selective probe meter that we use daily in the lab. ... "
