    How can I get the best solution if I have a problem with my product?

    You can find us on your manual or through your order.

    You will get satisfactory compensation if there are any technical problems with our power bank no matter whether the return window is closed or not. We will solve your problem within 24 hours.

    Getting hot when charging, is it normal?

    Yes. It does get a little bit warm when both fast charging and fast discharging. Please feel free to use it since this power bank has built-in over-heat protection.

    What's the biggest disadvantage of this power bank?

    The biggest disadvantage of this power bank is the weight of this power bank is around 12.99 ounces, which is just a bit heavy, but the weight matches the huge juice, fast charging, built-in cables, and wall plug, and broad compatibility.

    What is the real capacity of this power bank?

    It has 20,000mah but it ends up providing less than 20,000mah to your device because it loses energy when discharged, which is common for power bank.

    Customers like the built-in cables of the power bank. They mention that the attached cables are convenient, but short and feel fragile. The built- in AC input and multiple built in output cables eliminate the need for numerous cords. The LCD display is easy to read and the different cables tucked away neatly.

    I purchased this battery and 6 months later the built-in cord stopped working. Charmast immediately sent me a replacement. They are an amazing company and they stand behind their products and their customer service! I have purchased at least 8 of the smaller batteries and they have worked perfectly and I never leave home without one. These batteries are the best and I cannot recommend enough! I’d give extra stars if I could.

    I LOVE this thing. I brought it on a trip to Argentina, and my phone stayed fully charged the whole time, and everyone else kept stealing it to use it too haha it charges SO fast. Like in 20 minutes. I love how it easily plugs into the wall so I don’t have to carry yet another charging cord around with me. I’ve even started using this to charge my phone overnight instead of plugging it into the regular wall charger, and I bring it with me everywhere. A must buy!

     This power bank has everything I would like in one unit. Unfortunately I am again returning my second defective unit to give it one last try. First bank charged my new iPhone 15pro with be built in c charging cable, but it would stop charging after 5-15 min or so. This second unit, the cords worked well, but within 3 days, I was plugging it into an outlet using the fold down AC plug, I heard a small click. Now it feels a bit loose and will only charge via AC if positioned in the perfect position using things to prop it. I see it as a fire hazard so I avoid it altogether, I could charge it using a cord, sure but the AC option was something that really caught my attention on this bank. I’ve purchased a few of charmast brand banks and always had good experiences with them. If this third one doesn’t hold up I will try another brand bank with the A/C option j fortunately.
