Review: Quality product. - Fully needs my needs. And one of the few products that will charge my old iPhone 11 and my even older iPad. Just realize that it does take several hours to recharge fully. It came in at 81% charged and it took six hours to get to 100%. But now that I know that I can deal with it. Having the chords attached is great – you never go to charge somewhere and you don’t have the right cord. That more than meet expectations. It is a heavier product that you’re not gonna want to carry in your pants pocket unless you are wearing a belt but it feels really well made. They are doing a lot of building around me and I do have power outages, so I’m going to buy a second one. I’m so pleased with it. Just charge it up as soon as you get it and then instructions are to recharge every three months so it will be ready for you. Next day delivery! Have not had it long enough to review longevity of use.
Review: Good Buy! - Phenomenal product! Charges faster than any charger I’ve ever had. It even keeps my laptop charged. Doesn’t charge the laptop fast at all but it does give it a slow charge. If I use the charger daily, I recharge it over night. It will get down to 20% when I use it most of the day. It will recharge to 100% overnight. I wish you could see what the % level is without plugging it into my phone or to start recharging it. It would be good to have button you can push to see what the remaining charging % is. I would only buy a different one IF it was an even stronger charging one. But, I love the product for sure. Comes in handy often. I tad bulky and heavy but it works really well on everything I need to charge.
