Customer Ratings & Reviews

I bought this mainly to allow me to charge my iPad and iPhone without being tethered to an AC outlet, and it has served its purpose nicely. While it is a little heavy, and not small enough for your pants pocket (despite the name implying so), it does fit in my wife's purse or in my backpack's small pocket, which is portable enough for my needs. I'm able to fully charge (from 1% to 100% battery) the iPad twice on one full charge of the PocketJuice, which is nice. I do wish it came with a longer included microUSB to USB cable, but it's fairly easy to get another cable to use. It also would be nice to come packaged with a USB-to-AC power adapter. Still, it's a good product to have on hand, particularly if you don't have easy access to another power source.

A great product that does recharge electronics very fast. The only downsize is the weight

This is a great portable charger that does the trick. I was able to charge a dual go pro battery charger and iphone a few times over. You never realize how much you need one until you have one. I highly recommend the pocket juice.

Great for long flights, camping or when the power is out.

I purchased the Pocket Juice battery pack mainly for travelling. I find myself on long distance trips with layovers that I use my portable electronic devices and need an external source of power when outlets are not easily accessible or available. To that end, this battery pack is well suited and offers several charges of a phone and a couple for a tablet (both of which can easily and somewhat quickly be charged by this battery pack). The build quality is decent. The only con I can think of is that this battery pack is larger than expected. It is 20,000 mah so, I knew it would be large, I was just expecting it to be a little smaller than it actually is.

Portable chargers are great for travel. This one is a bit on the heavy side, but that is not surprising given the capacity. It should have enough power to keep our Surface or iPad going through a couple movies.

Although it takes hours to fully charge, I was able to fully charge my Samsung S7 four-five times over with this battery pack. The only drawback is its bulk. Its very heavy and I don't think you can carry this on airplanes.

This thing lasts forever. Its a bit big in size, (close to 6 inches in length, 3 inches wide, and 1 inch tall. (All estimates)), but its a 20,000 mAh battery so I'm not sure what I was expecting. It takes a while to charge, (about 24 hours for a full charge), but again, its a 20,000 mAh battery, so I'm not sure what I was expecting. This is my first portable battery of this size so I'm not sure if the size and charge time is normal for a 20,000 mAh, but it still lasts forever (I haven't managed to use a full charge in a day yet.) I'm very satisfyed with my purchase.

This battery pack really provided a surprising amount of power in a recent river rafting trip. It was a little heavy to carry but worthwhile in light of my power needs. Also seemed like a sturdy device.

Bought this on the road to help with charge my phone going from state to state. It is big and heavy but packs a good charge. Charges fast and I get several charges out of it to my iPhone 6s Plus.

This charged my iPhone 4 times while I was on a trip. It's several inches longer than my phone and a bit heavy, but it does what it's supposed to do. It charged my phone when I needed it.

If it wasn't for it being heavy, I would always bring it with me all the time. But I do love how it can fully charge my phone and tablet twice. If you don't mind the weight and the size, then this charger is for you.

The charger does what it states. It charges my cell phone and tablet fast. It's a little heavy for my liking and a little big for my purse, but overall it is a goodbye. I would buy it again if I need it to.

Holds 4 full iPhone charges and it recharges your phone fast! My only complaint is that it is a bit cumbersome in size, but it's the price you pay when you forget to charge your phone

This portable charger, while it takes awhile to charge will charge my iPhone at least 4 times, more quickly than my wall charger. With 2 USB ports it’s great for travel/

This charger is definitely worth it! I picked one up as a Deal of the Day and was skeptical as I have tried other chargers and they would discharge during storage and would be dead when you needed it. Not this one. Plus it’s got two USB charging ports and enough juice to charge two iPhones phones at the same time. Great on those trips to an all day amusement park. I loved the one so much that I bought two more to give to my kids for their book bag. Don’t miss out on this great product!

I’ve used this device for two years now and have to say it is incredible. At first i just used it as a travel companion for portable power and was never let down. Then I strapped it to my motorcycle and used it to keep my phone charged up while using my navigation. This is where it really shines. I could leave it on my bike for 3-4 days, using it throughout the day before having to recharge. I used it yesterday to keep my phone charged up while navigating the Road to Hana in Maui. When I started my phone was 86% and the charger pack had just 2 out of 4lights showing. I thought it would keep my charged for most of the day. I started at 9:30 am and returned at 9 pm. At he end of the day I just had one light and my phone was at 100% The pack kept my phone charged while in constant use for just under 12 hours with only 2 lights to start with. I was impressed. i thought for sure the pack would have run out of power, but it did not. This is the best power pack I’ve used, and would recommend it to anyone who needs reliable portable power.

Heavy and bulky but I actually prefer this way, since it feels solid and durable. I have 2 other lighter and slimmer power banks and they don't hold up the charge and perform as good as this one. It takes a while to fully charge it but once it's fully charged, I can be gone a few days with my iPhone 6s without worrying to find power outlet. It would be more convenient if it had flashlight like my other 2 power banks. 5-star if you can grab one on sale!

Very convenient to use anywhere at home. It's not always convenient to have a charging cable and wall charger in every room of the house. This Portable Charger is convenient for using at the kitchen table, on the coffee table while watching TV, and on the bedroom nightstand. This unit charges VERY quickly, I'm always impressed at how efficient the unit operates.

This portable charger packs the charge. It can easily and quickly charge your cell phone. I've had several other brands lower in price that die after a few uses, not the Tzumi. I can now travel and not fear I'll miss taking pictures on my cellphone because of a low battery. This device is heavier than the other charges I own, but it's absolutely worth it given the power and quickness of the charging. You can not go wrong with a Tzumi.
