Customer Ratings & Reviews

The Energizer Max Portable Charger is a fantastic option for anyone wanting a portable phone or tablet charger. It's the size of an average smartphone, so it travels well. The charge time is super fast and I can get 4 full charges (1% to 100%) before having to worry about recharging the charger. This is a great item to have while traveling or when you're at home and the power goes out.

Compact and powerful. I was able to carry this in my hand along with my phone while it charged. In no time, my phone had enough power for me to disconnect it.

Is the perfect thing to have on hand when you need to charge your phone but not near an electrical outlet or charging station. Great for travel

This is an okay charger battery pack. However, it suffers from the same issue as most all other packs; that it will shut off if only a low amp draw device is connected, plans were to use the pack to power a set of portable USB powered speakers for iPod listening on the go. But the pack would only start and power the speakers for about one minute and then turn off. The pack works fine to charge my iPhone 14, however it was a very slow charge that drained this 5000 mAh model. And only got the phone to 60 or 70 percent. When using to charge an iWatch, the pack had the same issue of periodically turning off before the watch was charged. I had to power on the pack multiple times, over an hour of time and only got a 70 percent charge on the watch. It works in a pinch, and will save you from a complete dead battery phone or device. But is not an option for quick charging or getting a full charge on newer high capacity battery devices.

This slim battery charger fits into purses and is great when one needs to charge up ones cellphone. I had to use it on many occasions.

Very slim & convenient at a great price. I can charge my Galaxy Z Fold 3 twice off a full charge.

Picked this up for traveling and has done a great job at topping off the phones when power outlets are not available.

Works well and is slim enough to fit in a go-bag!!

Excellent phone charger for emergencies when you have no other options

Light-weight enough that it's not a problem to keep it handy in my briefcase (because the phone always runs low at inconvenient locations!).

I love having these portable chargers available when I need them them. I like the fact that this one is light weight and small enough to fit into a purse that I can carry into a football game or anywhere where I can not carry a big purse. The charger will also fit into the pocket of tights that I have with side pockets. No more being without a charged phone. The only thing you must remember is that the charger has to have a charge and that is on you to have it ready when you need it.

Very happy with this back up battery. Can alwaya count on it to carry me thru till i can get tona place to use my wall plug.

I have purchased this item to have power when needed. It charged up quickly and provided good power when needed.

This product was just what my son needed when we attended his college orientation! His devices remained charged during the whole event!

[Employee of bestbuy] This always saves me when I forget to charge my phone, barely notice it with the magsafe holding

Lost my other power block and needed a good replacement. This is it. Does the trick and holds a charge for a while. Also like the 2 method charging as well.

Charger works well. I can get about two cell phone charges from the energizer charger.

Excellent portable charger for Apple iPhone, fit perfect in my backpack and charge the iPhone very fast.

The product charged quickly and functioned as promised. We will have to see howit holds up overctime but so fr so good.

Perfect small size battery pack to carry during travel.
