    There is nothing faster to charge your phone or other devices! My first one lasted 3 years. Love my new one. Be sure you buy the heavy duty charging plug (Samsung) or else it will burn out. (Don't use your phone charging cord)

    I purchased this battery backup for my girlfriend who was attending a two week residency program for her law school. It worked wonderfully well allowing her to charge her Samsung Galaxy S23+, her Amazon Fire tablet, and her Microsoft Surface with no troubles and quickly. I am looking to get the next one up from this model that will charge my laptop thanks to the results of this product.

    To be perfectly honest i like anker products but this one just fell a little short of expectations. This isnt my first one but definitely not the last i own. It will work for a quick few charges like it states yet their are other models thst just that have the cut above this model. Yeah it can fit in your pocket but hope you dont have slippery pockets(shorts/sweatpants) otherwise it might just end up on the ground or left somewhere you sat. Design is good and does its job but there are others that are around this price point(give or take 15-20) that are just better

    I Iove this power bank. Bought this for my trip - I am very happy with the purchase. It's worth the money. I had easily fully charged three phones alternately and still had juice in the power bank. It only used 1 "light" for the three charges. I kept the powerbank in the pouch even when charging my phone. I love the design simple but elegant.

    I’ve had the chance to use this product once since buying it. It charged my phone from 20%-100% and it still had a full battery life. I’m glad I upgraded from another cheaper one I had that barely charged to 100%. The only downside though, is that it’s a little too big for my liking and not as light as I’d want it to be.

    I used this on my european trip and worked perfectly…. It can charge up to 3 devices at once (2 via USB, 1 via USB-C)…. The USB-C is also how you charge the power bank which does take awhile. The power bank has 4 indicator lights for battery life 0-25%, 25-50%, 50-75%, 75-100%…. It’s an awesome product which i highly recommend.

    It charges my devices quick and easy. On my most recent trip it kept both my travel partner’s and my phones charged the entire time. We were traveling for 12 hours. It also keeps my Quest 3 charged while in use. For those that own one they know the Quest 3 is a battery hog. This charger is well worth the price.

    Great product! Charges my phone quickly. Lasts for approx. 3-4 charges for my Samsung Galaxy S21. It is a bit heavy to carry around in my purse but definitely worth buying!

    Best purchase I made all year. Went away for few days and my iphone kept running low. I kept the charger in my bag and charged my i phone while it was still in my bag. It charged up fast and friends borrowed it as well for their phones. The charge lasted for days and still works without being recharged. A little on the heavy side but absolutely worth it.

    These portable power packs are perfect for travelling - their size and weight make them ideal. I slip them in an inner pocket of my backpack and get multiple charges for my iPhone and iPad before they need recharging. Plug them in to recharge when you go to bed and they will be fully charged before you wake up. Incredibly pleased with this purchase!

    Nice slim design. Used to charge my single iphone 11 starting @ 10% charge to a full 100%charge within an hour. Provided my iphone with several charges and still had more juice left. Unit was just what I needed when camping with no electricity. Did not have to recharge unit over my 2 week vacation. Completely Satisfied!
