    I love this power bank because it is a great mix of storage capacity and mobility. It can charge your phone or tablet multiple times but isn’t as bulky as larger power banks. It is also great because it comes pre charged!

    Looks good so far. As others have mentioned the charger arrives with 88% charge and doesn't charge higher initially. I have not yet drained the power as reported by others to see if it will fully charge.

    USB-a port is off kilter with case and cannot use. Not sure if this was a return or just poor QC but the case also is scratched up. About the size of two modern cell phones stacked, convenient but wish it was functional. Glad I only paid $13 on Black Friday and not full price

    The portable charger I recently tried has been a game-changer for my on-the-go lifestyle. With a sleek design and lightweight build, it fits easily in my bag. The 20,000mAh capacity provides multiple charges for my devices, ensuring I never run out of battery during long days. The dual USB ports allow me to charge two devices simultaneously, which is incredibly convenient. It also features fast charging technology, reducing downtime significantly. Overall, this portable charger is reliable, efficient, and a must-have for anyone needing extra power while traveling or out and about!

    I bought this for myself for Pokémon GO Fest, and it crushed it. I was out in the sun all day, screen on full brightness, GPS and data running, and this charger never let my phone die. In fact, I still had power left after the event. It’s a bit heavier than smaller packs (as expected), but the battery life is totally worth it. Charges fast, lasts forever, and now it lives in my bag full-time. Highly recommended.

    Hold its charge pretty well, I like that it keeps track of how charged it is with the percentage display. Charge it up takes a while if you’re not doing it directly on the outlet and with a particular USB to wall plug converter, but this is very useful to keep the phone chargedfor prolonged trips or just throughout the day. Not too heavy either, though definitely bulky for one’s pants.

    Amazing! It charges my devices quickly and the battery lasts a long time. It is a bit on the heavier side, but worth it. It tells you how much charge it has and turns off on its own when your phone is not plugged.

    I recently bought this power bank, and it has been an absolute game-changer for my travels and daily use. It charges my phone 2–3 times on a single charge and does so quickly. The compact size makes it easy to carry in my bag or pocket, and it feels sturdy and well-built. I also love the LED indicators that show the battery level. It’s great for road trips, flights, or just getting through a long workday without hunting for an outlet. Definitely a must-have for anyone who relies heavily on their phone.

    I love that I can charge multiple devices at once. The charge for the battery lasts me a long while, but I may not use it as much as the average person. The size is a little bigger than I would like but it still fits nicely in my small backpack.

    I have purchased so many charger banks for trips and things that literally work for a day or dont work at all. I came across this one and decided to give it a try as the reviews looked promising. When i went in store to pick it up, the sales associate said its the only one he will use and told me how he uses it. I have had time to use it now and it has been great! You can even charge multiple devices with it at the same time. We charged up 3 iphones one day and it still had lots of hours left.

    Needed a portable charger to for trips because not all public chargers are available, so i decided to get one of my own and not worried about finding a public charging station for my electronical devices. The product is very good and it can charge my phone, my buds and my tablet and still have charge left.

    Great power bank that is very powerful and charges fast. It has an LCD display that shows how much power is remaining. Only thing I would say is it's a bit bulky so keep that in mind.
