Customer Ratings & Reviews

This is really handy and portable while travelling.. it took around 2 hrs to fully charge this battery, once charged i can use it to quickly charge my phone almost two time...

This power bank takes forever to recharge. Like around 8 hours or so. I think this is taking too long for a 4000 mAh battery. From some other reviews for a 20,000 mAh battery from another brand, it takes about the same length of time to finish charging. This is the downside of this product. Other than that, it does support fast charging for my Samsung Galaxy S8. It won't fully charge my phone from 0% to 100%, but it was able to charge 80% - 85%. Decent enough for me, although I would get a larger mAh battery.

This was a gift for a relative who is traveling out of the country and will be taking a lot of photos. It is small enough to carry and powerful enough to charge a phone and a camera.

Bought one for each of my very active, and very connected kids. They kill their phone batteries in half a day, but with this they can fully recharge not once, but twice if necessary

Got this for my son because kids don't like to keep their phones charged. Now he has no excuse not to pick up the phone I pay for when I call him.

It was very cheap like $16-22 I believe, it’s flimsy and not as durable as my other portable charger purchase. It works. It will give you 3.5/4 bars on your phone.

This is so far the best portable charger yet. I've tried a few and this one got me though my son's school concert. I Was able to take many pictures and still have juice after.

Very easy to use. Great to have in a pinch. Gave these as Christmas gifts. Everyone said that they didn't think that they needed one. In the end, they all loved it.

This is a good backup for charging on the go. The speed to fully charge the device is not as fast but it serves its purpose.

Exactly what I needed when I am out. Have had a hard time always keeping my phone charged. Now I am able to charge when I am not where I am able to plug in. Love it!!

It is hard to see which phones this product is compatible for so I bought the wrong one but if you have the apple charger you can still use it. Works good!

Great to have on hand to provide that extra charge you need on the go. Just be sure to have a lightning cable to charge an iPhone as it only includes a Micro USB.

Ran my iPad with it and it recharged it faster than a normal USB plugged into the wall would have. So far, I am loving it. Hope it continues to perform as it has.

This: Tzumi - PocketJuice Solo 4000 mAh Portable Charger for Most USB-Enabled Devices - works well for the $4.99 I paid for it on a "Deal Of The Day".

This gives enough juice to charge a phone on the go and has come in useful to me several times. Definitely worth the money.

For almost $5 as a door buster, you can't go wrong for such a low price, given that a USB-based mobile device will eventually need a quick charge in a pinch!

This charger is cute and compact and kind of a life saver when you're in a rush. Does get a bit warm though.

I had to use my charger the other day . My other charger broke when I was away from my home for the day. This charger came in Handy. Works Great!!!!!.

Nice to have this extra battery backup for those times when you are out and about and realize you are low on phone charge, works as intended.

Works in a pinch when no other power source is available. Small and easy to bring along. Downsides are short cable and it’s easily misplaced.
