    Works, but lacking

    Posted
    ZaneRoss82

    As a basic battery bank / charger this works fine. It will fully charge a larger device like the Samsung Note 8. The Digital read out of battery percentage is also nice. Fairly thin, and doesn't get overly hot when in use. Things I don't like: No USB C port even though the picture on Best Buys Website shows a USB C port. This guy only has USB Type A for charging your device, and MicroUSB to charge the battery bank. It doesn't work with the Qualcomm Wireless fast charging specification, so although it will wirelessly charge your device, it's very slow. It won't charge smaller wireless devices like a smatwatch. Guessing its because they don't pull enough watts. It starts charging, but the bank eventually turns itself off because its not detecting enough wattage being pulled. Overall, for the price I would just stick with normal battery banks as this is very slow and doesn't support the newest connection available.

    Simple and Effective Portable Wireless

    Posted
    N900

    I got this portable wireless (charges my phone without having to plug it or my phone into anything) and was skeptical. I have a Note8. I don't need something that charges too quickly, just something that I can use to set my phone on when it gets low without having to look for a plug. It exceeded my expectations. It charges relatively quickly. I went from 70-96 percent in about two hours. Again, not fast, but not slow either. This is perfect for those with a desk job who don't want to have to plug in. It is small and pocketable. The price is really good for working so well with the Note8. I wouldn't say it is "quick charge" but it is as fast as the older Samsung wireless charger I have. Again, absolutely worth the price. Maybe a little more. I was pleasantly surprised. I highly recommend it.

    This product (and I purchased 2 of them to use with my 2 new iphones), would continue to turn off after various random charging minutes. In addition, when I purchased them, I was told it would charge through the very thin phone cases each phone has to protect it. This was not true...it would not charge at all wirelessly unless I removed the phones from their cases and then once plugged in and as mentioned above, they would not charge the phone to a full charge and would turn off randomly.

    If your phone has a fast charge ability.... Don't get this powerbank. It's SLOW and drains QUICKLY. I use a note 8, and this thing WON'T charge your phone fast enough to keep it full. I use it while I'm navigating with my phone or using Spotify. The wireless charging feature works...buts it's SLOW also. 2 stars because it works.. BUT it doesn't do it's job WELL.

    Gives Extra Juice

    Instead of buying just the wireless charger. This serves as powerbank plus a wireless charger. I bring it with me all the time at work and wherever I go. It charges faster with the cable but if you forget to bring the cable then this will give you juice. Not fast to charge but extends your phone when needed.

    Poor Performance - Tzumi PocketJuice

    I returned the Tzumi PocketJuice portable charger. It took forever to charge my iPhone 8 Plus and never fully charged the phone. I'm not sure if it was defective or not. The only thing I liked was the LED battery life percentage detector.

    This gem had 85% battery in it right when I opened it and saved my life on the walk home! I love that it’s wireless because I forgot my charger at home. I would purchase again next time I’ll purchase the ones with 8,000+ mAh though!

    This battery pack is cool and it comes in handy the best part is that it will charge your phone wirelessly and it charges your phone fast aswell. This is cool and it’s a must have if you are always on the go.

    Wireless charging where?

    Item did not charge efficiently. The main reason I purchased the device was because I have an IPhone X and love to use my wireless charging, but this device failed to do so. Most likely to return.

    Worst Portable charger i ever used. The wireless charging only works for about 3 minutes then stops working. It also takes forever to charge a phone even with the wire....

    This charger works very well, so far. It's only been a couple of days, but it is working as advertised. I will update in a couple of weeks IF this changes.

    Wireless charging is useless it takes a while to find the sweet spot to actually charge it and the wire it comes with makes charging harder and it dies really quickly

    Great for minimizing the amount of cables you carry on the go. It’s a qi charger and Inuse it to charge my iPhone 8 Plus. It’s light and I LOVE the battery percentage display.

    I like the wireless aspect because I have both iPhone and Samsung with the wireless I don't need the different cords. Simply charge and go.

    As a wireless charger the unit turns off during charging even though battery is not charged. Also charging is extremely slow.

    This is the worst product i've ever purchased. It barely charges one device to 50%, much less charging 2 devices.
