    Product performed as described, but be AWARE: there is NO fast charging. Please read package i promise you wont regret it. Second major issue is, even with oackaging claiming the usb-c is an in/out (which means you should have the ability to charge the bank with a usb c to usb c cable connected to higher speeds block. This does NOT work. The only way you can charge is : you must use the cable that came with the bank. Insert usb c end of cable into charger rhan the orher end of rhe cord is a usb A which you must plug into a wall charger with A compat. Despite the bank taking 3 hrs ro charge, it did work for about 2 weeks; resulting in chargikg fine, but when plugged it into my phone about 30 sec later it would display a warning of very slow charging. About 3 days later it failed to charge at all.

      Hi MikeK,
      Sorry for the trouble you experienced with this power bank. Based on the product specifications, this model provides a maximum total output of 15W, so charging speeds will be standard rather than fast‑charge levels. The USB‑C1 port is designed for both input and output, and the unit can be recharged through that port using a USB‑C to USB‑A cable connected to a USB AC adapter.

    One failed unit and website support is insecure

    This reviewer received promo considerations or sweepstakes entry for writing a review.

    The power bank has failed and just blinks "188" -- it was just displaying a garbled number before. I have not found a way to reset it. I wish to contact support but their website is not secure! When it worked (and I still have one working of two), it's a pretty handy power bank and I got it for a good price on sale. Nothing too fancy in terms of charge speed in or out, but the LCD to tell you the charge percentage is nice. I'd like a way to get support where I don't have to type in my whole address through an unencrypted website though. I'm pretty sure this is just bad luck but I don't have a way to rectify the issue.

      We’re very sorry to hear one of your units failed and that you encountered concerns with the website security. The "188" blinking typically indicates an internal error. Unfortunately, there is no reset function for this issue, but we’re here to help.

      To avoid entering personal details through a form, you can email us directly at [email protected]. Please include your product model, serial number, proof of purchase, and a brief description or photo/video of the issue. We’ll take care of the rest and assist you with a warranty replacement if applicable.

      Thank you for your honest feedback — we’ll also pass your website security concern to our team for review.

    Worked great for about 4 months. I think the battery brick itself gone bad out the blue. I have another later model that I ordered from Amazon and it’s working still. Would love to give this another chance but it’s barely been 6 months and mine stopped working.

      Hi CMZ3,
      Sorry the power bank failed after just one use — that’s definitely not the experience we aim to deliver. If you purchased it only a few days ago, you can return it directly at the store. If you're still within the return window and prefer support, feel free to reach out at https://support.energizerpowerpacks.com/, and we’ll help troubleshoot or arrange a replacement.

    Only charging to 16% of capacity after about 30 cycles of use. Very disappointing! Also, the on/off button is too easily pushed unintentionally while the power bank is in a pocket or a bag.

    I've been using the Energizer MAX 10,000mAh power

    This reviewer received promo considerations or sweepstakes entry for writing a review.

    I've been using the Energizer MAX 10,000mAh power bank for a while now, and it's been working really well for me. The 10,000mAh capacity gives me plenty of juice to recharge my smartphone multiple times throughout the day, which is perfect for travel or long days out. The 15W USB-C charging is a nice feature - it's fast enough to get my devices powered up without waiting forever. I really appreciate having 3 ports available, so I can charge multiple devices at once when needed. Whether it's my phone, earbuds, or other accessories, this power bank handles it all. One of my favorite features is the LCD screen. It's super convenient to see exactly how much battery life is left rather than guessing based on LED lights. This helps me plan when I need to recharge the power bank itself. Build quality feels solid and reliable, which is what I expect from Energizer. It's compact enough to toss in my bag without adding too much bulk or weight. Overall, this is a dependable power bank that does exactly what I need it to do. If you're looking for a trustworthy portable charger with good capacity and multiple ports, I'd definitely recommend giving this one a try.
