FEATURES
- Current control driver for low impedance injectors
- 4 channels
- Available in three current versions:
8A/2A
4A/1A
2A/0.5A
TECHNICAL DESCRIPTION
Peak and Hold 8A/2A
- Controls up to 4 injectors with impedance below 1.5 ohm
- 16 Bosch 160lb/h (1600cc) injectors (4 per channel)
- 8 Siemens low impedance injectors (2 per channel)
- 4 MSD low impedance injectors (2 per channel) (with 2 ohms impedance per injector)
- Controls up to 4 injectors with 1.5 to 3 ohms of impedance
- 8 Bosch 160lb/h (1600cc) injectors (2 per channel)
- 4 Siemens 83lb/h injectors
- 4 MSD injectors (with 2 ohms impedance per injector)
- Controls up to 4 injectors with 3 to 7 ohms of impedance
- 4 Bosch 160lb/h (1600cc) injectors
Dimensions: 115 x 90 x 33mm
TO DETERMINE WHICH PEAK & HOLD YOU NEED
- Grab a multi-meter and select Ohms 200
- Touch the positive and negative leads of multi-meter together to measure resistance (record this number...i.e. measured 0.3)
- Then take the positive and negative leads from multi-meter and put on each terminal of the injector. Doesn't matter the order. Record this measurement
- Take the ohms measurement from Step 3 and then subtract the number you got in Step 2 (i.e. Step 3 4.8ohms - Step 2 0.3ohms = Total 4.5ohms)
High Impedance Injectors - Above 7ohms - No Peak and Hold Boxes are needed.
Peak and Hold 2A - 3ohms to 7ohms (Bosch 160lb/hr).
Peak and Hold 4A - Below 3ohms to 1.5ohms.
Peak and Hold 8A - Below 1.5ohms (Billet Atomizer*).
All low impedance Billet Atomizer Injectors manufactured after Nov. 2012 require 8A regardless of measured resistance.
*Billet Atomizer Injectors - Anything prior to serial # C300**** should only use the 4A/1A. This only applies to injectors manufactured prior to Nov. 2012.

Excellent quality with just the right amount and type of connection points I needed!
Extremely good quality. I've used many Anker product over the years and this one didn't disappoint! Needed it to run a laptop on my network in isolation mode and to have accessible connections for ethernet as well as a wireless mouse and extra cooling fan as my laptop has only 1 standard size USB 3.0 port. This is the mini version so It won't necessarily supply enough juice to charge your laptop at the same time (there's another 8 in 1 made by Anker for that) but it can supply enough power to maybe get you through a very trying session, very short term. Super-easy to connect and just works. Fits comfortably in my carry bag too. Very light weight, good heat dissipation although I didn't really have any or at least not much. Compatible with all the connectors you see in the picture. In my case at least, it wasn't a luxury it was a necessity and it proved it's value immediately.

USB ports charge.
Relatively cheap, lightweight, and better than most. It gets warm, but not hot. The Video adapter was immediately recognized by my Macbook and works flawlessly at all resolutions made available (much higher than Windows PCs) I used it both as the recipient of my 65W Mac charger, and the Mac received its power from this device; I also had the 65W Mac charger plugged directly into the Mac, and this plugged into the second USB-C plug on the mac. It works (HDMI monitor) both ways. It says that the ports are not for "charging", however be aware that they do charge when devices are connected, for example my iPhone to the extra USB-C port, or the USB-A port. My Logi back-lighted keyboard lights up too. I don't know why they say it is not for charging. Perhaps it is simply saying there are no ports expressly intended to do charging without connecting to your computer.

High quality and all the right connection types
This works great. I've used it for both my MAC and PC. I really love the Ethernet on the end and the HDMI connections (which modern laptops don't include at times). This is a great adaptor and highly recommend.

One complaint
Works very well and solved port issues on my X1 Carbon. My only quibble is that the C interface cable from the unit to the PC is a bit too stiff and tends to lose connection if things move about.

Perfect for my use
Works as intended. Solid build quality and works with my Windows laptop through the USB C connection. I wish the product description would clarify that the USB ports do not support video.
