    Although it's a bit bulky, I bought it for using whenever I need to on the go. I recently use it at a wrestling live event and charge my phone from this pack. It took about several hours to charge the battery pack. I highly recommend getting this.

    Great product! This purchase is actually my second one. Whole family loves them my daughter uses them for switch and IPad. Will charge my iPhone pro from 10% to full like 10 times. We charge them and they set on the sofa table because we have a large open floor plan with no outlets close. Also there great to have during power outages.

    Size is bulky, but definitely holds a charge and recharges your phone or accessories within a decent time. It's not a fast charger, but not slow either. Lasts for days!!!

    Great portable power with lots of juice. Charges efficiently and rather quick. A little on the bulky side but makes up with multiple ports and good back up.

    A bit on the heavier side. Came mostly charged from the store; purchased two and one was at 80% and the other 90%, charged fully before leaving for a weekend camping trip. I didn't fully charge our phones in an attempt to conserve battery but after three days of charging our phones back to 60% or so from <15% both chargers were still over half full. Definately taking on our next camping trip.

    A good portable charger but heavy

    I purchased this power bank due to it's high capacity that I can use during my travelling. I tried this on my iphone and one of my android phones. This charges the phones pretty fast. I like the LCD charge indicator. compared this with another power bank I have and found few drawbacks. no built-in cables and no prongs to connect to a wall outlet. The major drawback I found is the weight of this power bank. This is very heavy compared to similar models in the market. Hence, decided to give a three star rating.

    No, I would not recommend this to a friend

      Hi protector,
      Glad the high capacity and fast charging worked well for your devices, and the LCD indicator is useful. The weight you mentioned is a common trade‑off with 30,000mAh power banks since larger batteries require more cells, which adds bulk. Built‑in cables and wall‑outlet prongs are design choices that vary by model, but your feedback is valuable and helps highlight what features matter most when traveling.

    I brought this battery bank because my previous one no longer works. I’m glad I did, because a day later, my neighborhood had a power outage that lasted all day. This battery bank charges my phone very quickly within 30 minutes and the bank still have enough charge to charge 2 more phones.

    Great solid battery, takes several hours to charge but trust me, will last days. Charged mine to 100 percent, ive been using to charge my phone and ipad multiples times 100 and it only takes 10-20% of said battery. Solid purchase if you need a sustainable power source, plus with 3 ports for potebtial use, i can charge three things at once or, use it as a extendor, as long as it has more than 1% battery, i can connect it to charge and still use the other 2 ports as a additional charging station.

    Its a great powerbank! I got it last minute before a week long vacation in yellowstone. It was ready to pick up within an hour and it came at 80%. It lasts a loooong time, it's heavy duty (I actually dropped it on a concrete parking lot with minimal damage), and the fast charging is actually fast. I only wish that it had a wireless charging option, but that's not a big deal to me.

    Must have battery bank for phones

    I was in need of a new battery bank after I found mine had decided to swell like a balloon. I usually look for the cheapest alternative. But that is probably why i have been in this predicament a few times in the last year. Bestbuy had a sale going on I couldn't pass up. This was the same price as a battery bank with half its capacity and a name I didn't know. Does take a day to charge just about but i can charge my phone 8 times from 0% to 100% and that is something I am impressed with.
