Customer Ratings & Reviews

This is a great product to have you can charge 3 devices at once!

It’s might be big but it sure comes in handy! I’ve charged multiple phones with it and I’ve haven’t had an issue!

Lots of capacity. Good for long trips and convenient for multiple devices.

[Employee of bestbuy] Charges my tablet fully and is surprisingly light.

Good charger, chargers fast and holds a long charge

Love it despite being a bit big and heavy (easily fit in a fanny pack though) and overkill for what we needed it for apparently. Needed something for a full day at Universal Epic Universe and then a full day at Disney World Magic Kingdom to keep two cell phones and R36S charged. Don’t think after 3-4 charges that the energizer dropped much below 75%. Probably didn’t need to recharge it between park days but did.

Great item works as advertised as I work on the go and need it to keep my phone charged

Lasts long and charges many devices for a week !!!

Powerful high capacity portable charger. Only uses 10% of its battery to charge iphone up reach 80%~. Slightly bulky but Travel and concert approved.

Extremely useful power block for charging! It does what it says and has a big supply.

Good power bank charges really good and last very long

amazing device that can last extremely long. Heavy but will last you for days/weeks

[Employee of bestbuy] Very useful, gets multiple charges to phone, love the digital display

Recharges quickly. It’s a little heavy-but manageable.

Battery that is enough in all situations. Just getting it fast on juice.

Purchased this battery for a trip to Southeast Asia and it has come in handy many times. I kept it in my backpack as I traveled. I recommend to anybody looking for a reliable and long lasting charge.

Its a little slow but ive charged my phone several times over and was able to keep my lapto on life support for over an hour.
