The difference and pros and cons of mobile power software and hardware
The software version is more powerful than the hardware version.
The hardware version is continuously running and the software version is automatic. There is a load to run. Life is longer than hardware.
The hardware version of the LED power display is not accurate enough to achieve the effect of breathing lights and marquees. The software version is intelligent. The software version is more accurate than the hardware version.
The conversion efficiency of the hardware version is generally 75%. The conversion rate for the software version is 85%. That is to say, the mobile power of the same capacity will charge your mobile phone, and the software version will charge more times than the software version. This point is more obvious when the capacity is larger.
The software version has a longer service life, and the software version uses a control IC that can be programmed to control the display of the indicator light and is more intelligent. The hardware version simply uses a simple circuit to control charge and discharge.

 

 

Advantages of the software version:
The software version is dual IC control. It is easy to realize synchronous rectification, high efficiency, low heat generation, and flexible function changes, which has become a development trend. Software version optimization is mainly to speed up the main loop. Currently, the main loop is less than 200us. Fast control is achieved by integrating a dedicated comparator. For example, a DC-DC comparison is performed at 5.0 V, and pwm control is turned off unconditionally at 5.5 V.
Input interface: V8 port, micro usb (for Android port, flat port)
Power display: 4 levels of LED lights display power, intelligent automatic shutdown in non-working state.
Charge and discharge protection: The circuit board has a built-in lithium battery protection IC with overvoltage protection, overcurrent protection and undervoltage protection.
Charging input requirements: The best match is the charger above 5V1A, and any other 5V constant voltage power supply can be used as the charging input power.

Purchasing & Delivery

Before you make your purchase, it’s helpful to know the measurements of the area you plan to place the furniture. You should also measure any doorways and hallways through which the furniture will pass to get to its final destination.
Picking up at the store
Shopify Shop requires that all products are properly inspected BEFORE you take it home to insure there are no surprises. Our team is happy to open all packages and will assist in the inspection process. We will then reseal packages for safe transport. We encourage all customers to bring furniture pads or blankets to protect the items during transport as well as rope or tie downs. Shopify Shop will not be responsible for damage that occurs after leaving the store or during transit. It is the purchaser’s responsibility to make sure the correct items are picked up and in good condition.
Delivery
Customers are able to pick the next available delivery day that best fits their schedule. However, to route stops as efficiently as possible, Shopify Shop will provide the time frame. Customers will not be able to choose a time. You will be notified in advance of your scheduled time frame. Please make sure that a responsible adult (18 years or older) will be home at that time.
In preparation for your delivery, please remove existing furniture, pictures, mirrors, accessories, etc. to prevent damages. Also insure that the area where you would like your furniture placed is clear of any old furniture and any other items that may obstruct the passageway of the delivery team. Shopify Shop will deliver, assemble, and set-up your new furniture purchase and remove all packing materials from your home. Our delivery crews are not permitted to move your existing furniture or other household items. Delivery personnel will attempt to deliver the purchased items in a safe and controlled manner but will not attempt to place furniture if they feel it will result in damage to the product or your home. Delivery personnel are unable to remove doors, hoist furniture or carry furniture up more than 3 flights of stairs. An elevator must be available for deliveries to the 4th floor and above.
