Generally, people just need to fully charge their phones once in a day. OISLE’s design conception is to find a perfect balance between practicability and exquisiteness, and with the best quality.
Please NOTE :
Power bank has two regular standard of capacity , one is the battery capacity, one is the rated capacity. The 4225mah power bank, being labeled 4225mah/3.7v core capacity be converted to rated capacity 3000mah/5v. and the 2800mah power bank, being labeled 2800mah/3.7v core capacity be converted to rated capacity 2000mah/5v.
Why exist this difference?
The most important reason is the conversion rate. Because most of power bank’s battery voltage is 3.7V, and power bank needs to increase the voltage to 5V when charging the mobile phone, which making the power bank’s conversion efficiency only 3.75/5=74%, Also include generated heat when battery voltage boosting, and various of wire consumption, Electricity and self-consumption. these points add up to account for 30%-40% of the power of the mobile power source.So the 4225mAh power bank can really be used by us only about 3000mAh.
Also, The conversion rate of the entire mobile power industry is basically in the range of 60%-70%. Please kindly noted.

Ordered an external battery for the iPhone 6s, came quickly to the cash register pyaterochki near the house. Externally, I liked it very much, it sits quite tightly on the phone, but it does not break on a thick cover. In the kit there were two cases of transparent thin, one from my phone, the second from some other iPhone of the same size only with two holes under the camera and a flash, Plus a short cord for charging. while everything is fine, charges. The track was tracked before receiving. arrived in 7 days. let’s hope it works for a long time.

It fits my iPhone 11 nicely, looks unique, and the surface is pleasant to the touch. The charging speed is not fast charging, but it will not affect the use of the phone all the time. recommend this shop

Reached in 9 days instead of 5. the delivery itself changed to 5post. Upon receipt there were problems, decided to call in support. The battery is generally pleasant, there is a slight smell of plastic. The material is something like soft touch, it’s nice to keep. Slightly rocking as it holds on one port for charging. Pasted an additional strip from the kit, it became better. The switch button is slowly flickering, clicked on pressing. The complete wire is somewhere 15 cm, charges. In general, the purchase is satisfied, the phone in the hand sits confidently, although it became heavier. By the time of charge I will test.
