    This portable charger is very practical and easy to carry. It is compact, lightweight, and perfect for everyday use or travel. The charging speed is good and it works reliably when I need extra battery during the day. The build quality feels solid and it is simple to use. Overall, it is a convenient and dependable portable charger that does exactly what it promises.

    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!!!

    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.

    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.

    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.

    Love it despite being a bit big and heavy (easily fit in a fanny pack though) and overkill for what we needed it for apparently. Needed something for a full day at Universal Epic Universe and then a full day at Disney World Magic Kingdom to keep two cell phones and R36S charged. Don’t think after 3-4 charges that the energizer dropped much below 75%. Probably didn’t need to recharge it between park days but did.

    Powerful, portable charging device

    This is a very powerful charging block, which is awesome to take on a trip whether it’s a weekend or a couple weeks. You carried on the plane and if you happen to be on a plane that doesn’t have power in your seat and you’re on a longer flight, it works perfectly highly impressed with its portability. It is a little heavy because it has so much power but it’s well worth having this product.

    This charger works well and as advertised. Barely moved when I charged my phone. Haven't had for very long but no complaints. It is a bit bulky and heavy but I keep it in my bag so that's not an issue for me.

    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.
