1. Look at the appearance
When you first see them, you may wonder, will it be heavy?
Actually, for self-reliant people, it's more What matters is “whether it takes up space or not.”
2. Review product performance
Whether the appearance suits your eyes is actually very subjective. As a highly functional product, appropriate performance is the key to choice. For external power supply, there are three main parameters: battery capacity, power, interface type and quantity.
1. Battery Capacity
Capacity is the most important specification of a battery, which determines how long it can be used on a full charge. The mobile power bank we usually use for mobile devices. Phones typically use milliamp hours (mAh), but theLarge capacity outdoor batteries will use Wh as a unit, because the number of converted mAh is very large. The kilowatt hour of electricity that we know is 1,000 Wh.
2. Power Supply
The size of the power supply determines what electrical devices that power supply can power, which also determines what you can do outside with it. If you just charge cell phones, laptops, drones, lights, etc. outdoors, 100W of power is enough, but if you want to have an outdoor picnic, use some small portable appliances, such as rice cookers, outdoor hot water kettles, low-pressure dryers. electric hair, etc., require more than 500W power.
3. Interface Type and Quantity
The power server has a total of 7 output ports, including 1 AC output, 2 DC outputs, 1 car charger and 3 USB-A; the littlePower stations have 9, including 2 AC, 2 DC, 1 car charger, 2 USB-A and 2 USB-C.
4. Self-charging speed
Continental power supply (DC input), car charger and solar charging panel are the traditional standard configurations of outdoor power supplies.
3. Review safety performance
In addition to using high-quality batteries and high-quality flame-retardant materials, the safety of outdoor power supplies is also related to the waveform of the inverter and shell material.
Outdoor power supplies are typically used outdoors or in vehicles. They are inevitably subject to shocks, falls, compressions and, in extreme cases, collisions and crushing. To protect the lithium battery cells inside, you need to have a strong and sturdy shell. In this regard, the small power plant and the small power plantelectric are doing well. The shells of both are made of PC+ABS VO grade flame retardant materials. This material has good scratch resistance, impact resistance and drop resistance, and adopts the American standard. UL Safety The current highest level of laboratory flame-retardant material standards can effectively prevent leakage and electric shock compared to metal enclosures.
4. Watch the usage experience
① Folding handle VS fixed handle: The folding handle is not only convenient for storage, but also can be used as a mobile phone holder, freeing your hands when watching movies. dramas.
② Large green light screen VS black and white screen: LED screen lighting is mainly convenient for night use.
③ “Flat” VS “Vertical” AC outlet: The vertical AC outlet is close to the ground when charging for a long time, the charging head wire bends easily when chargingtouches the ground. A pair of AC sockets are flatLying on the opposite side not only avoids bending of the charging cable and prolongs the life of the plug, but also makes reasonable use of the limited space to prevent plugs from different sizes to influence each other.
5. Look at the brand history
After all, outdoor power supplies are not cheap consumer goods worth a few hundred yuan. Once quality issues arise, safety is at stake, so it is. always important to choose a reliable brand.
