Reliable & Fast Charging – A Must-Have!
I’ve been using this Anker Portable Charger for about four years, and it has never let me down! Whether I’m traveling or at home, this power bank charges my devices super fast, even my tablet. The 20,000mAh capacity means I can get multiple charges before needing to recharge it, which is a lifesaver on long trips.Recently, I bought one for my godfather in Cuba, where power outages are common. It works perfectly for keeping his phone and mini fan charged when the electricity goes out. The dual ports are a great feature, allowing him to charge two devices at once. This is hands down one of the best portable chargers I’ve ever owned—durable, reliable, and powerful. If you need a high-quality battery pack, I highly recommend this one!

Longstanding charge
Used for travel in Greece, Italy and London so far. Pack in by purse and use as needed. Lasts a long time and can charge my phone and friend’s phones too. It is larger and heavier than the smaller/less powerful chargers, but doable if you need this amount of charge. It stays charged for a LONG time: put it in storage shelf mid-January, pulled out for next international trip in June (same year) and it was still fully charged.

Great product, great company
I just love Anker power banks. I have been using this brand long before it became popular. I have at least 15 Anker power banks of various sizes and designs. In fact I still have the very first one I purchased at least 17 years ago. Don’t use it for much but still works great and holds a charge. I only buy Anker power banks and cables. I traveled on an airplane 4 times a week for three years, these are life savers…

Great charger
This charger is great. It holds the charge to itself for a very long time. And I use it for about 3 to 4 days before I have to charge it again and I charge my cell phone with it throughout the day which I have to charge because I’m on it a lot for work and it doesn’t go out fast and it charges my phone quickly and I love that it’s mobile so I can move around with me. The only week it does take a long time to charge, but it’s worth it whenever it is charged.

Great portable charger for you backup power supply
The family affectionately calls this "The Brick," as in "Can I borrow The Brick. My phone is almost dead." I've used it to change a small MacBook Pro and many iPhones. For a portable charger, it has plenty of power. While it isn't light, it is very reliable. It's the center piece of my charging kit that I carry in my backpack where ever we go. My only con is that since it is such a large capacity, it can take awhile to fully change even with a faster USB-C charger.

Hurricane-prone area STAPLE
I love the simplicity, yet functionality of this charger. I was going to get a MagSafe charger for my phone, but opted for the corded version and I’m so glad I did. Not only can it charge my family’s phones, but also iPads, flashlights, chromebooks for school, and so much more. This will be perfect if we ever lose power due to a storm. It’s heavy, but not so much that it’s not portable. I also like that it’s not complicated to operate. Just plug, push the button and charge! It charges my iPhone 13 in about an hour and still has plenty of charge for other devices. It does include a USB charger for the battery bank. Simple and easy to use.

Excellent power bank
I love Anker products, they've been on top of their game for a long while now. This is a great power bank. It is slow to charge, but this is obviously due to it's high capacity, so just be aware of that. Only complaint is that the capacity is not 20,000 mah as stated. I'm getting just about 17,000 mah on my meter, several attempt to drain the battery completely and recharge have all yielded the same result. You'll lose roughly 20% during transfer of energy, so this leaves you with about 13,600 mah. Just another thing to be aware of, doesn't take away from how good it is.

Works like a charm
Charges devices fast, and holds a lot of power. It can keep my quest 2 going for multiple hours, which is nice since it's old and the battery isn't what it used to be.Only thing that would make this better is if it had a digital battery display instead of the 4 dots.
