Compact size, little heavy for something as small as it is. But that is overlooked after watching a 3-1/2 hour video on a tablet, and still had enough charge left, to charge my phone. Very pleased, enough so, that I went back and purchased a second for the wife to use on her trips. Excellant pricing and quick shipping.

Superpak is outstanding, orderd 2, on one of them the LED light didn't work, but that was not an issue for me. Took one on a 4 day trip, charged my phone (GS8+) about 4 times (50-100%), iPad a couple times, Bluetooth speaker (JBL charge2), and MS Surface tablet every day (20-100%). It worked flawlessly, and charges devices quickly, it does take about 8-10 hours to recharge itself, but if leave it plugged in before I go to sleep it's always full when I get up, so I don't have to have 5 charges for all my devices, just one for the battery pack and rotate all my devices through the battery during the day to top them off. (Bonus: get a micro-USB to USB-C adapter for your phone, and you only have to have one cable, you can also plug a device into the battery and change the battery at the same time, aka pass through, so when you wake up your device and Superpak battery are full)

Super excellent price, I only ordered one, used it with my 10 inch tablet and watched a 3-1/2 hour video, then midway thru found my galaxy S8 was low, so I plugged that in as well. The movie ended, the phone was charged and all was good, and plenty left in the battery bank. Woke up the next day thinking about how well it worked, logged back on to Tanga and purchased a second. Couple days and it was at my door. They are not refurbs, they are new items. Great to have on hand for emergency use.

This battery is slim, not too heavy, and quickly charged my phone in less than half the time with my wall outlet charger. Holds a charge for a very long time. Charged 3 phones and 1 tablet using only 25% of the battery. Charges Android and IPhone well with their certified chords (not included).

THIS IS MY LIFE SAVER THIS BATTERY. S
