Ranked in these QuestionsQuestion Ranking
Pro Easily replace the internal batteries
The Zilu Smart uses standard 18650 high capacity batteries inside of its closure. So for those that want to be able to have a long lasting charger and not have to worry about throwing it out when the batteries inside die this is a good choice as replacements can be easily found at most places rechargeable batteries are sold.
Pro Large capacity
The Zilu Smart has a 4400mah battery inside, which for the price of $24 is quite a bit more than similar priced chargers out there.
Pro Battery lasts longer than most portable chargers
Pro Informative incremental LED
There is no screen on the device in order to save room, but there is a circular led that has 10% incremental segments that will let the user know within 10% how much the device is charged or needs to be charged.
Pro Environmental packaging
All Anker products come in compact recyclable cardboard boxes, which not only makes them easy to open but also environmental friendly.
Con Power to weight ratio is subpar
There are other portable chargers that use smaller and more powerful batteries, which allows the casing to be smaller and weigh less as well. The Zilu sadly is a bit heavier than most, but that seems to be at the cost of using 18650 batteries, which can be easily replaced compared to non replaceable smaller options.
Con Multiple reports of the device failing
Multiple people have reported that the devices stopped working within the first month of use.
