Comparison ANKER 535 PowerHouse vs Jackery Explorer 1000

Power that a device can consistently produce for an indefinitely long time without any unpleasant consequences. For normal operation of the charging station, the rated power must be at least 15 - 20% higher than the total power of all devices simultaneously connected to it.

Some electrical appliances (in particular, units with electric motors - refrigerators, air conditioners, etc.) consume significantly more energy at startup than after reaching the operating mode. For such a load, the peak power of the charging station must be taken into account - its indicator must be higher than the starting power of the load.

Full-size USB A connectors are popular in computer technology, they are standardly used in adapter chargers for 230 V household networks and 12 V auto sockets. In charging stations, such outlets are widely used for charging gadgets.

- The total number of such ports can be very diverse ( 1 USB, 2 connectors, 3 ports and even 4), since it allows you to connect for charging, and in some cases for power, various low-power devices - smartphones, tablets, power banks, lamps, etc. .

- The strength of the power. The maximum power output through the USB A connector to the device being charged. Note that different ports of the charging station can output different power (for example, 1.5 A and 2.1 A). In this case, the highest power strength is usually indicated.

— Power. The maximum output power in watts (W) that the charging station is capable of delivering through the USB A connector to one charging device.

Full size USB A ports with fast charging support. It allows you to charge your smartphone, tablet or other connected device much faster. The charging process takes place at increased power, and the current and voltage at each stage are regulated in such a way as to remain within the optimal values. However, it should be borne in mind that in our time there are many fast charging technologies and not all of them are compatible with each other.

- The strength of the current. The parameters of the current issued through the USB A fast charging connectors. Note that different voltage and current parameters can be output to different ports of the charging station. This item specifies the current values at a certain voltage (for example, 5 V / 3 A, 9 V / 2 A, 12 V / 1.5 A).

— Power. The maximum power in watts (W) that the charging station is capable of delivering through the USB A fast charging connector to one charging device. High output power allows you to speed up the charging process. However, the appropriate power must be supported by the device being charged - otherwise the speed of the process will be limited by the characteristics of the gadget.

USB type C ports are smaller than classic USBs, and they also have a convenient reversible design that allows you to connect the plug in either direction. USB type C was originally designed to be able to implement various advanced features: increased power supply, fast charging technologies, etc.

Since the port is relatively new and quite powerful (there are USB type C with a power of 60 W and even 100 W), the total number of such connectors is often limited to 1 port, less often two).

- The strength of the power. The maximum power output through the USB type C connector to a charging device. Note that different ports of the charging station can output different power (for example, 1.5 A and 2.1 A). In this case, the highest power strength is usually indicated.

— Power. The maximum power in watts (W) that the charging station is capable of delivering to one rechargeable gadget. The high output power of the USB type C port allows you to speed up the charging process. However, the appropriate power must be supported by the device being charged - otherwise the speed of the process will be limited by the characteristics of the gadget.

The ability to replenish energy reserves in the battery cells of the charging station via the USB type C connector. This port itself is small in size and has a convenient double-sided design, thanks to which the plug can be inserted in either direction. However, in charging stations it does not always work as an input interface.

DC connector for a distinctive round plug (like those used in many laptops) used to recharge the battery of the device. Note that DC- in plugs may have different sizes, and chargers with such plugs may have different operating voltages. In practice, this leads to the fact that finding a suitable charger for a portable station is not easy, you need to be especially careful when searching.

A large two-pole connector for connecting batteries, chargers and all kinds of equipment where reliable contact is required for the sake of ensuring stable operation of the equipment. Anderson Port is resistant to moisture changes, can be used both for indoor and outdoor mechanisms. Thanks to identical mating parts, a pair is formed by two identical connectors, which are rotated 180 ° relative to each other. Most often, Anderson port is used in mobile homes on wheels.

— Li-Ion. The key advantage of lithium-ion batteries is their high capacity with small dimensions and weight. Also, Li-Ion batteries are not subject to memory effect and can charge quite quickly. Of course, this option is not without its drawbacks - first of all, it is sensitivity to low or elevated temperatures, and if overloaded, the lithium-ion battery can catch fire or even explode. However, thanks to the use of built-in controllers, the likelihood of such “accidents” is extremely low and, in general, the advantages of this technology significantly outweigh the disadvantages.

— Li-Pol. An improved version of lithium-ion technology (see the corresponding paragraph): the liquid electrolyte in Li-Pol batteries is replaced with a solid polymer. At the same high capacity, the batteries have become more compact, there is practically no “memory effect” in them, and the likelihood of fires and explosions in the event of critical violations of operating conditions is minimized. The downside of these improvements was increased cost and increased sensitivity to frost. However, most often these shortcomings are not significant.

— LiFePO4. Lithium iron phosphate batteries are a modification of lithium ion batteries (see corresponding paragraph) designed to eliminate some of the shortcomings of the original technology. LiFePO4 batteries are characterized by a...large number of charge/discharge cycles, chemical and thermal stability, low temperature tolerance, short charging time (including high currents) and safety in operation. The likelihood of an “explosion” of a LiFePO4 battery when overloaded is reduced to almost zero, and in general, such batteries cope with high peak loads without problems and maintain the operating voltage almost until discharge.

— Li-Ion NMC. A type of lithium rechargeable battery using a complex alloy in the manufacture of the cathode. It contains nickel, manganese and cadmium. This “recipe” allows you to increase the power of a power source based on Li-Ion NMC elements. Batteries of this type have a high specific capacity and a stable discharge voltage, provide a long operating time of the charging station with high performance, are characterized by a complete absence of “memory effect”, maintain functionality over a wide temperature range and are fireproof.

— VRLA. Acid batteries with a regulating safety valve to release excess gas. The abbreviation VRLA stands for Valve Regulated Lead Acid. Batteries of this type have a sealed, non-separable design and come in two types: AGM VRLA (the battery plates are equipped with a layer of fiberglass absorbent) and GEL VRLA (with a gel electrolyte in a jelly-like state). Batteries with a control valve are resistant to deep discharges, do not require topping up with distillate throughout their entire service life, and do not emit hydrogen or oxygen.

- Semi-solid State. An advanced type of lithium-ion battery (see above), which combines some of the characteristics of liquid and solid batteries. It uses an electrolyte that is in a semi-soft or gel-like state, making the batteries more resistant to leakage than traditional wet batteries. Semi-solid state technology allows for a significant increase in the energy density of cells. As a result, it is possible to make compact batteries with high energy intensity.
