    This portable charger is a great invention. It's very convenient to use. It's not bothersome to carry. Just put it in your pocket and plug your cell to it and it starts to charge. great purchase.

    The battery life on this is quite good. It's a little odd that when I plug in mt anker to charge my phone I have to push down on the anker charge button to activate the charge. That's no problem now that I figured that out. Works great!

    This is something i have been wanting for a while, a battery back that I can take every where and charge some of my devices on the go if im running out of battery. It works good, no issues and it has everything I need.

    Love the sleek look and feel, charged many items several times over already. FYI - it can only charge from USB-C to regular usb, not reversed, which may be inconvenient for some people who are used to a different charging option.

    Picked this up as backup for some international travel and it was super helpful to have on more than one occasion. Good for a few charges and conveniently sized. I only used it for phone recharges, didn't try anything bigger like a Switch.

    Anker does it again. I got this charger because my son loves to play on his switch and always runs out of battery. This comes in clutch. So worth the price. And also helps charge my phone and my wife’s phone when we go to Disneyland.

    Works just has the description of the product states. We use it for are older galaxy S6, which does not hold the charge very long. When the charge run out on the Galaxy S6 tablet we plug the Anker unit into the Galaxy S6.

    Another Good Anker Power Pack

    My last power pack was an Anker. I had no complaints with it. Lasted about 4 years. My only issue with my new one was that it was supposed to include a travel pouch, as described on the packing box. It did not. Not worth the trouble of taking it back to Best Buy to inquire. I have my old one.

    Compact and Powerful

    Today there are a multitude of portable chargers of which Anker is one that very rarely disappoints when it comes to mobile accessories. This portable charger was exactly what I had envisioned as it is compact and holds plenty of charge. It does charge devices extremely quick and seems to hold enough power to charge the number of devices as advertised. The only disappointing aspect is that it does not have usb-c charging, but this is not uncommon in many portable chargers though it still would have been beneficial to have the option. Many "usb-c' powered devices are usb-a to usb-c anyways so there are really only a handful of devices that would truly benefit from usb-c charging so I can understand the reason Anker elected not to include this feature. Overall all though for the price I would definitely recommend this product as it is sleek, powerful, and easy to use.

    I have ordered it twice one as a gift because it is amazing, I get at least 3 full charges out of my Fold 3, and I am impressed with the weight and overall size it is slim for that much power

    My Anker battery is great backup; especially when traveling. No more waiting for an opportunity to charge up my iPhone at a busy airport. Have my charger right on my purse and it’s much safer!

    This charger has plenty of capacity for charging 3 iPhones. Worked out great when touring Europe. The higher capacity units are too heavy and the smaller units do not have enough capacity.

    Works great! Love it. Weight of it makes sense of the longevity, which seems to have a medium lasting to it. If I were to gauge for what would feel endless, it’s charge life is like half of that.
