1. The maximum current is 1.5A when outputting 9V. Exceeding this current will automatically protect the shutdown boost.
2. When outputting 12V, the maximum current is 1.2A. Exceeding this current will automatically protect the turn-off boost.
3. Output cable length 0.5 meters, output interface is 5521/5525 male
4 Use this product must comply with the law of energy conservation; that is, output = input + loss (line loss + boost loss), analogy: the output capacity of 12V-1A when your input USB charger or mobile power carrying capacity exceeds More than 5V3A; According to my experience, the general route charger is 12V-1A, but the actual use does not require 1A of the current (the standard 1A refers to the maximum current, generally leave a margin). Use 5V-2.1A Mobile power is sufficient (again emphasize that those who must buy a regular mobile power cottage Although the target is 5V-2.1A but many can not reach, if you find in the use of current is not enough to move, you must consider a better point High-current mobile power

Boost line advantages:
1, exquisite and compact, use does not occupy space.
2. The quality of the core booster circuit is stable and reliable, the interference of the double-panel design is small, the conversion efficiency is high, and the standby loss of the micro-ampere quiescent current is small.
3, wire quality is reliable, the plug is equipped with a tuning fork spring, plug more tight.
4, flexible and diverse applications. Any small home appliances, equipment, instrumentation, tools, etc. that use 12V/9V power adapters, within 9W, can be used with this adapter cable + mobile power.
* Note 1:
The output 9W is full-load working state (5V2.1A input). If the load needs to work for a long time, it is recommended to reduce the power or enhance heat dissipation. No heat sealing status is recommended and the load is less than 7W.
Rest assured with the load:
Routers, cats, switches, miniature camera/monitor cameras (without infrared), driving recorders (actual power consumption is generally around 12V 0.3A), car air purifiers (generally less than 5W).
* Note 2:
DC5521, DC5.5 * 2.1 plug specifically refers to: plug-in metal part of the outer diameter of 5.5mm, the inner diameter of 2.1mm. Please confirm the load plug specifications before buying!
Plug specifications non-5521 are currently known to have:
Tenda router, totolink (for 5.5 * 2.5mm specifications, the same diameter, different diameter, so it is particularly easy to make mistakes, please pay special attention.)
Electronic dog (mostly designed as a DC3.5 plug)
* Note 3:
About 5V power supply, currently encountered a very few cases connected to the charging treasure can not be used, after verification is charging treasure output ripple is too large (there are two cases are connected charging treasure does not power, but replaced the notebook USB power supply router light) .
Because the charging treasure originally only used for charging, the ripple requirements are not high, some charging treasure manufacturers do not design the filter circuit to save costs, the output ripple exceeding the standard, this will interfere with or even damage the follow-up electrical circuit (in order to say that some charging Po injury phone is the ripple problem).
