"You are right. The actual capacity is less than what it says on the box because of the charging voltage.It is the same for all other power banks.
"Discharging voltage of a standard Li-ion battery is 3.7V, while the output of the Jackery battery charger is 5V. To convert 3.7V output up to 5V through the circuit, plus conversion loss, the final effective capacity into a device of the Jackery Giant + 12000mAh – will be around 12000*85%*(3.7/5) = 7548mAh."
If this was helpful, please let me know.
The power pack is compact and easy to travel with. It has some weight to it but it certainly isn't too heavy to be easily portable. Charging it is simple, as is operation. The single button makes powering the pack on and off easy. The flashlight is a nice option, although it's not that bright and unlikely to be used by most. It could certainly be handy for those camping.
The pack charged my iPhone and Apple Watch each night without issue and still had plenty of power left even after a couple days in the woods. With the iPhone plugged into the 2.1A port, charging is faster than it'd be from your typical iPhone charger (the higher amperage is closer to the iPad charger), while still charging the Apple Watch in the 1A port at standard speed.
A great combination of size, power, and price, this power pack is a great blend of all the things you should look for. I'm very happy with this pack and highly recommend it to anyone looking for more power on the go.
Update- after speaking to Jackerys customer service (or lack thereof), they mention nothing about a warranty on the product & instead want me to "send a video of the problem" so that they "can give me a solution later." Maybe I was just one of the unlucky ones to receive a faulty product, but I def learned my lesson & won't be buying from Jackery again.
With that said, there are some downsides to this particular model, in comparison to its competitors in the 12k-13k mah class.
The charging input and output are both below average in comparison to other batteries in the marketplace.
The charging input of this battery is below average at only 1.5a. Almost all of its competitors (Ravpower, Anker, Aukey, EasyAcc ) offer portable batteries in this mah class with 2a inputs. Input amperage determines how quickly the battery recharges. Most 12k-13k batteries can fully charge in about 6-7 hours, but because this battery has such a low charging input, recharge time is relegated to 8-10 hours.
The charging output is also below average. This battery has 1 port that provides a 1a output, and a second port that provides a 2.1a output. In truth, 2.1a is enough to charge almost any phone or tablet – but again – most competitors provide substantially more charging output, by giving you at least one 2.4a port.
Jackery could easily have updated the ports on this product from the time it entered the market in 2012-2013, to reflect current technology standards, but they haven’t. It’s probably the main reason why this battery bank is substantially less expensive to buy than its competitors (old technology).
My comments above may sound harsh, but I don’t hate this battery bank. I’m just trying to paint an honest picture so people understand how this battery bank compares to others in the marketplace. My current phone is a Galaxy S5 and this portable battery works just fine for my purposes. For the $20 I paid for it, I think it’s an excellent value – but I understand its limitations, and you should too.
