This is must buy product for those who likes nature and wanted to work outside of the house or office Or who does frequent travel where you don’t find the electric outlet. This product is all in one and holds a good amount of power and can be use for small mixers ,music system, laptop at park, beach , mountain. I recently used this product at the park where I could not get the power for my laptop and this power bank was perfect in that condition to us. The battery do not heat up during the whole charging period or when you charge fully. You also can plug USB charger for phone, and AC outlet to charge your laptop or any other device at the same time and there is no issue. This also comes with the case where you can store and protect the power bank.

A generally good concept, except for some shortcomings.Everything has a cost, not just in price but in tradeoffs. For anyone with an already heavy computer bag, this additional weight and bulk are going to be noticed immediately. If you want power, you pay for it in several dimensions. There is no free joule.Experience shows that it takes about 4-5 hours to charge a depleted battery pack. That is about twice as long as it will power a typical Thinkpad using the AC outlet, though you can use the AC outlet power while the battery pack is being charged. In one test I completely removed the OEM battery from the Thinkpad and the battery pack successfully powered the computer for 2.5 hours on AC OUT without dropping below the recommended 20 percent minimum charge level. Note that the 20 percent is an industry recommendation but not mentioned by the distributor/manufacturer.For a typical laptop that calls for 19-20 volts DC, a far better design solution would have been a DC OUT at 19 VDC. Some Kristonia power products evidently have this feature. Instead, with this device, you have to use AC OUT to run through your laptop AC/DC converter/adapter, and that involves enormous inefficiencies. You lose energy in the DC=> AC conversion within the battery pack, then again with the AC=>DC conversion at your laptop adapter, and the battery pack then has to run a fan to cools its conversion innards, resulting in not just power losses but a bit of noise that may not be welcome to everyone. That fan appears to stay on when supply AC power out, rather than only operating when the internal components require cooling. Another design shortcoming.The "user manual" is the size of a post-card, with type too small to be read normally.To the device distributor: Redesign this thing for a 19 VDC OUT port, and a set of DC tip/connectors for a versatile range of laptops, and you will have a 5-star winner.Nice points:The power status display is a plus.The carrying case is a nice bit of foofoo.None of the components run hot.The AC/DC external adapter meets US safety standards (though the battery pack unit doesn't)The watt-hours output is clearly marked on the battery pack case to shore up your arguments with the unschooled knuckledraggers at TSASpeaking of TSA, the advertised 99.9 watt-hours would mean this is as powerful a "spare battery" pack as TSA and airlines would normally allow for carry-on.If you know how to press buttons, you should be able to operate in pass-through mode, charging the battery pack from an AC source while also supplying power to the AC and DC out ports.Summary: the product is a limited success, reflecting some unfortunate engineering tradeoffs resulting in inefficient power supply and limited utility of the device.
