    This is a pretty small battery pack that's easy to carry. It's lightbweight an easily fits in a pocket. It's a bit wider/taller that a credit card and about 1/4 inch thick. It's slightly bigger than the Energizer model from previous years. I like the LCD panel that displays the precise charge level, rather than the 4 lights of the old model that could only indicate a charging range of 25%. (1 light, charge level of 0% to 25%, 2 lights, 26% to 50%, etc.) This pack has 2 USB-C and 1 USB-A ports, all along the top. There's no more micro-USB on the side, nor a second USB-A, as with the past versions. Has a high enough capacity to fully recharge most phones with a bit extra left over. Definitely recommend.

    The Energizer MAX 5,000mAh 15W USB-C 3-port Power Bank is a lightweight & portable power solution. Weighing in at only .26 pounds, this battery is the perfect companion when away from a charging spots, as it should give you up to 18 hours of additional phone life. It ships pre-charged, so you can use it right out-of-the box. Mine had an 86% charge when I opened it up. The Energizer MAX has a large bright LCD display, which is easily readable even in full sunlight. It also includes a 3ft USB-C charging cable. The Energizer MAX has three ports, one USB-C In/Out, one additional USB-C and a USB-A port. The main USB-C port is rated 3A. I would definitely recommend this product.

    My favorite feature of this power bank is that it displays the remaining power level. It can be quite tedious to make an educated guess as to how much power may be left, like some other power banks show, so this is a very beautiful feature! It charges decently quickly, whether for your phone or to apply more power to the power bank itself! Lastly, the pricing felt like a steal compared to other competitors who may charge 15 dollars or more. I paid about 8 dollars for this, and I couldn't ask for more of a nice, simple power bank!

    Overall, I enjoy the charger! The battery life is better than expected for the size of the battery and it's easy to travel with! It's great for day trips or even running quick errands. I would definitely recommend for everyone and for such a good price.

    Pros: Great size to put in your pocket on the go or in a small bag. Charges kind of slow but better than wireless charging. This is great for emergency purposes and small travel trips. CONS: I wouldn't charge a tablet with this because it will take along time to charge up and probably drain the battery quickly.

    I always keep one of these on the go. Some days my battery usage is high. This charger is helpful when I am having a high battery usage day in the city. It is not the fastest but it gives enough charge to finish the day.

    I got this for my wife to use during Pokémon GO Fest, and it was a total win. We were out all day with screen brightness cranked and apps running nonstop. This little charger kept her phone powered the whole time and still had juice left. Super compact, lightweight, and charges faster than I expected for a 5,000mAh pack. Great emergency backup or daily carry, especially for gamers or heavy phone users.

    The Energizer is an excellent everyday power bank compact, reasonably priced, and equipped with a convenient LCD display and multi-port versatility. It’s perfect as an emergency backup for your phone or smaller devices during errands, light travel, or daily commuting. Just don’t rely on it to fully charge tablets or power high-demand devices for extended use.

      Hi AleR,
      Thanks for the thoughtful review!
      We’re glad to hear the MAX 5,000mAh power bank is serving you well for everyday use. Its compact size, LCD display, and multi-port setup make it a great companion for quick errands and light travel. You're absolutely right—while it's perfect for phones and smaller devices, it’s not designed to fully power tablets or high-demand gear over long periods. For those needs, a higher-capacity model like our 20,000mAh or 30,000mAh options might be worth considering.

    I have tried different brands of power bank before but this energizer power bank is very good. It doesnt heats up and is very light to carry. I like the percentage display to keep track of battery. And has different types of outlet too. Will definitely recommend this.

    I went and bought this cause if the power Goes out i might need this for my phone. BestBuy had some flash sale or something And i got this for $4 (including tax). So That being cheaper than Wal-Mart, why Not buy it. It has a USB-C & USB-A port So it will be good for a phone or a flashlight When you got no power after a storm. To me its good to have a back-up. And we All need our phone to work at all times. Also has a LCD screen for power level.

    This is the perfect size and output to take hiking. The larger mAh portable chargers were a little too bulky when you are trying to pack as light as you can but this one was perfect. Good for 1-2 charges on a samsung android phone. Great safety devise to ensure you always have your phone charged.

    I purchased this portable battery charger for my vacation trip to NYC. It worked great, light weight and easily fit in my small hand bag. Battery charged my phone super fast and lasted for 2 days. For the price I highly recommend this as a backup for any trip.
