Anker Ultra Compact High Speed VoltageBoost Technology Reviews Summary

Device Longevity

Pros:

• "I have been using this Anker battery power bank for 2 years."
• "Still a little on the heavy side. My only dislike is that it only charges one phone before it needs charging again."
• "This is my second one of these that I have purchases, and there is a reason I would buy more."
• "Quality construction, works great."

Cons:

• "I did not damage this product or overuse it, but less than a year after buying it, it won't charge anything at all."
• "I bought this product in late 2022, worked so well at first, now it won't charge."
• "I have had good Anker products in the past but this portable charger does not work."
• "This is my 3rd Anker battery. The others lasted easily over a year for my iPhone. This one doesn’t take a charge."

Compatibility

Pros:

• "I’ve been using this portable charger for years with my iPhone 8 and IPAD. Slim and lightweight with multiple charges."
• "This battery pack is great for extra battery life when away from home. My sons use it after-school, before practice and after practice on his long days at school."
• "I have used this to charge my MacBook and it has saved me on the go at college."
• "I’m a blind individual and hesitated on buying this power bank, because of all the customer issues with charging. Along with unreadable instructions. I’m glad I made the purchase."

Cons:

• "However it DOES NOT work with IPhone 15!! It actually drains the phone battery."
• "I received this for Christmas. I have an iPhone 15 pro max it does not work for me at all."
• "Unfortunately after charging it, it supposedly should charge my iphone 13 pro at least twice, it does not."
• "I thought this was able to charge using the USB-C connection as an output and thought this would be a great buy, but it only charges the actual battery pack via USB-C as an input."

Charging Speed and Efficiency

Pros:

• "Great product for charging devices while traveling or camping."
• "I tested this charger twice prior to vacation. It did charge my phone very slowly both times."
• "It charges my phone 2x from under 10% phone battery."
• "This thing is small but has a lot of power. I can charge my iPhone 13 Pro Max almost twice on this thing before it dies."

Cons:

• "this portable charging bank does the job for when you cant find an outlet a d your phone needs to charge but it heat up after a few min and idk if its my charger but i feel like it charges my phone slow."
• "Absolute garbage, not only does it take FOREVER to charge this device, this device also takes FOREVER to charge my devices."
• "Took most of the day to charge fully, seemed to drain fairly quickly too considering it should have been able to charge my phone twice but barely made it even though power bank was fully charged."
• "It takes up to 3 or 4 hours to charge the battery from 0%."
