    Bought this for Pokemon Go Fest. It works really well, even if it is bulky. This battery is allowed on Allegiant airlines since it is less than 28k mAh, but it isn't like they checked my batteries. This battery feels sturdy and it lasts for a while, especially for Pokemon Go. Pokemon Go drains a lot of phone battery, so this battery pack does the trick.

    Although heavier than I expected, this battery charger has replenished my phone multiple times (about 25% per charge) before needing recharging itself.

    Great power bank! This Energizer 20,000mAh charger is super reliable. Charges my phone multiple times and even works well for tablets. The LCD screen is a nice touch, showing exactly how much battery is left. A bit bulky, but worth it for the capacity. Great value for the price!

    Excellent product. I primarily use it to power LED lights and a small fan in the rooftop tent in my overland vehicle. It has enough power to last all night. Additionally, if I fully charge it and then dont use it for weeks on end it retains full charge.

    Consider weight vs storage size

    Works well and it’s great that it has extra ports for different wires. It’s noticeably heavy when kept in a small handbag or purse but given the sheer amount of power it stores it makes sense, so that’s kind of the price you pay for extra charging. Consider physical weight vs storage size as the deciding factor when you purchase a portable charger. If weight is more important don’t go for this one. If you don’t mind weight and just want a lot of storage go for it.

    Workhorse of a charger

    I bought a couple of these for a family trip, and they are workhorses that did what they were supposed to do. This battery has hours of capacity and is very reasonably priced. I purchased it for the value and was not disappointed. Be aware that these are bulky and kinda heavy, but you can charge a phone several times (3 or 4?) if this thing is fully charged. I think it's good.

    This little pack for the cost is awesome. I use it when im put and about, though its going to come in good when my son and i are playing pokemon go over the holidays. It does a fast charge with one device connected, and regular charge with two.

      Glad to hear this power bank is keeping up with your adventures! It’s great that you’re getting fast charging with one device — that’s exactly how the smart output management is designed to work. Hope it powers plenty of Pokémon catches this holiday season!
