For, to choose the right battery you need to analyze options, that it should have, and plug type.
Necessary parameters for the charging device notebook:
- 1) The DC voltage is given in volts (V) – must match the value specified on the laptop (theoretically tolerance is about 1 AT, but not always).
- 2) The intensity of the current is measured in amperes (BUT) – this value represents the maximum current, that can charge the power source. This parameter should not be less than, than is required for a laptop, but there may be more (but the stick is not necessary to go too). Connecting to a power source which is too little amps can result in damage to the notebook, because the components will not get enough current.

For the above example, multiply x 19V 3.42 = 64,98W, happened, что прекрасно подойдет зарядное с питанием 65W (you can buy and more powerful, but with preservation of the first indicators ).
parameters established – time to move on to the selection of the plug.
Необходимо измерить внутренний и наружный диаметры штекера. In the case of our Toshiba exits, что мы имеем штекер питания с внешним диаметром 5,5 mm 2,5 мм внутренним. Now, where have all the necessary information, you can continue to search. В поисковой системе сайта https://maxpower.com.ua/ enter the brand and power settings, eg “Toshiba «19V 3,42 5,5 2,5»” and voila – we have a product of interest!
