Most PlayBook owners along with BlackBerry 7, iOS, and Android users have fallen prey to old underpowered cellphone chargers. It is easy to assume that since they all charge via USB or MicroUSB that they should all work. Truthfully there is a critical factor that plays into all mobile chargers that that is the output amperage. With BlackBerry 10 the folks at BlackBerry are recommending at least a 750mA charger to consistently charge the BlackBerry Z10. This is because “Chargers supplying less than 750mA may not provide enough power to sustain a charge on the device during heavy use.”
I have been pushing BlackBerry’s super cheap 1.8A chargers on BerryReview since they push out more than double that charge for your house and car. As a comparison BlackBerry is shipping out a 750mAh charger with the BlackBerry Z10. Terrence sent me over some pictures of old BlackBerry chargers. You can clearly see that some of the older charger do not push out the required 750mAh. Please do not use them with your BlackBerry Z10 or else it will barely charge if at all. You can usually see what amperage your charger pushes out by checking where it says output. It will usually either be measured in milliampre like 750mA or in the case of high amperage chargers like the Premium PlayBook charger it will be measured in ampere like 1.8A (which is 1800mA). The “h” in the “mAh” acronym just stands for hour so “mAh” is “milliampere-hour.”
Here are some old chargers to test your new skills out on:
