This is not the case. I've got it connected to an old iPhone so I can watch it on Apple TV. It can be left on all day without becoming too hot.
As long as there's a USB port, it'll suffice.
Of course, simultaneous push and pull draws are bad for any battery, so avoid it if at all possible.

With its glossy finish, this 10000mAh power bank looks great. It appeared to be smaller and thinner than I had anticipated. However, if necessary, it can still be carried in pants or a bag. br>br>I used this to recharge a Samsung Galaxy Note 9 with a battery capacity of 4000mAh. So, theoretically, this power bank could recharge a dead Note 9 twice, but I'm not convinced that this is the case. It's possible that if you turned the phone off and left it unattended for a while, it would charge faster. When you plug in a spare battery, you continue to use your phone, as do the majority of people. When used in this way, it appeared that the capacity of 10000mAh was overstated. br>br>The digital readout is nice. br>br>However, unlike the photo, it did not come with a lanyard. In response to a question I posed, the seller stated that they would consider adding one in the future. The lanyard in my photo was one of ten that came in a pack that I also bought on Amazon. Would I suggest it? br>br> Yes, it's more for commuting purposes. Not ideal for backpacking or, as in my case, running in the woods while wearing a hydration vest. The square shape, in my opinion, just adds to the packability. able to compete with even bigger lipstick (cylindrical) chargers.
It's a little heavy, but I was able to charge my iPhone twice at Disneyland and T-Mobile. The core remained at 45% of its original value of its original%.
This handy charger will come in handy on your next trip! You use the included cable to charge it, and the portable charger holds several charges for your phone. It is extremely effective. Furthermore, the two USB ports with outputs make it suitable for use by a family on vacation. What a fantastic offer!.
Holds a charge and looks after me when I'm in need. It will, in fact, look after myself and a friend! It's surprisingly light for how powerful it is!.
This powerhouse of a charger is one of my favorites. Light as a feather! It's perfect for traveling and sightseeing because it can charge both my iPhone and Android. This is an excellent investment!.
This is exactly what I needed because I have an iPhone 6 that needs to be charged all of the time!.
It failed to deliver on its promises. It charges my iPhone 7 Plus one and a quarter times instead of the manufacturer's claim of five times. My GETIHU power bank, which is 40% less expensive but has a four-time charging capacity.
Unpredictable Power Packsbr>br>Rough calculations indicated that charging the internal battery would require approximately 10,000 mah. However, only under 7,000mah was provided until the batteries were completely discharged from 100% to 0%. A continuous discharge battery with a capacity of 1000 ah was used. The discrepancy, I believe, is due to the DC converter circuitry's efficiency. I'll put the second unit to the test and report back. br>br>I purchased one of these power banks and returned it for a refund. The first one didn't always turn on to charge a connected device; it took up to 30 seconds to turn on at times. It would turn on and off at random times. I tried several cables and charged several different devices with the same result. br>br>When the replacement arrived, it behaved exactly like the first power bank - it would not charge any of my devices. br>br> It was unable to be turned off. The LED Battery % charge display was illuminated when the box was opened. If the device was left stationary for an extended period of time, it would eventually turn off, only to relight when it was moved. When it was turned off, it would not turn on to charge a connected device that was connected to a cable, just like the first one. I tried several cables and charged several different devices with the same result. br>br>It also came with no instructions, so it was never clear exactly how this thing was supposed to function in the first place. br>br>It also came with no instructions, so it was never clear exactly how this thing was supposed to function in the first place. br>br>I wouldn't have accepted a third to try out if I hadn't been given the option of returning it (presumably for a refund).
