When a lipo's balance connector is plugged into a lipo balancer, the balancer can both monitor the voltage of each cell and if need be, discharge any high cells in order to balance the pack. For example below is the breakdown of cells (voltage) by color in the above photo when using a volt meter. As such you, or more often your charger, can use each pair to access a specific cell. This ability exists because there is a wire going to the (-) and (+) of each individual call. As such there will always be one more balance wire than the number of cells, in this case 4 wires for 3 cells.ДЇinally it's time to get down to the real reason for having the balance connector, the ability to monitor and manipulate each individual cell. The balance leads are connected at both the (-) and (+) of each cell. Then the main leads are connected to the outer most (-) and (+) tabs. The best chargers support their fastest rates on each port at the same time, without added devices slowing anything down.As you can see this pack is composed of 3 cells wired in series. Combined power output: After testing each individual port, we test the combined output when each is pushed to the maximum.Then we repeat that test on each chargerвЂ™s other ports, confirming that every port behaves as expected and that, combined, they match the indicated output. We start with the power load set to 0 amps and then turn it up until it matches the promised amperage, ensuring the voltage stays within a range of 4.75 volts to 5.25 volts. This setup allows us to finely control the power flow and determine whether it matches the advertised rate. USB-A ports: We test the maximum power draw from each port by plugging in a variable power load and an ammeter.

We use the Total Phase USB Power Delivery Analyzer and its Data Center Software to measure and record this data, including the advertised power profiles, the steady state output, and whether any errors occur in charging.

USB-C ports: USB-C uses digital communication between devices to verify charging speeds in a way that USB-A doesnвЂ™t with the right tools, you can interpret exactly whatвЂ™s going on in the communication between the charger and the device youвЂ™ve plugged in.

But if size is not a chief concern for you, a slightly larger charger with multiple ports is often a better value than a smaller one that can charge only a single device.

Multiple USB ports: This feature is nice to have, but itвЂ™s not as necessary as it used to be now that particularly small, affordable, and properly performing options are more readily available.

Accepting a little more volume is fine if that means more power or more ports, but all other things being equal, smaller is better.

Size: Although absolute size is not the top determining factor, we naturally prefer smaller chargers to larger ones.

We use this as a comparative figure, ruling out models that are unnecessarily expensive.

Power-to-dollar value: Simply put, we consider how good of a value each charger is for the total power it can put out across its ports.

Considering the generally low prices of these chargers, you wonвЂ™t find significant savings by choosing a charger slower than 12 watts.

USB-A ports with 12-watt or QuickCharge 3.0 output: USB-A charging maxes out at 12 watts (5 volts, 2.4 amps) for Apple devices and many Android phones, though some of the latter can charge faster via QualcommвЂ™s QuickCharge 3.0 standard.

Those more-powerful and more-expensive chargers are better options if you need to charge a tablet or a laptop. Although having higher output doesnвЂ™t hurt since your device draws only as much power as itвЂ™s rated for, paying more for power you wonвЂ™t use doesnвЂ™t make much sense, so thereвЂ™s no reason to buy anything over 45 watts specifically for your phone.

USB-C ports with 18- to 45-watt output: USB-C ports allow many phones to charge faster-with the right cables-drawing power at 15, 18, or 20 watts (the higher two levels are designated as USB-C Power Delivery, or USB-C PD).
