Background

General

For a number of years there have been all kinds of power banks that held conventional primary or rechargeable batteries and have a USB-A socket to allow charging cell phones.  This combines that function with the additional capability to jump start a car.  These new devices also typically have a flashlight function.  They are packaged in a shape that's similar to a cell phone, but somewhat larger.

The first one I heard about is called Lightning Pak (official web page).  They make a number of packs with different capacities (6.5, 13 & 15 AH).  A friend has the small one.
Then I got this one branded Annke (official web page).  They make units rated for:
CP-02A  8 AH,
CP-03 12 AH,
CP-05 6 AH
The paperwork that came with is says it's 8 AH capacity.  But measuring the capacity depends very much on what load is used so I expect there will be a lot of claims about capacity that don't specify the test conditions.  More on that later.
The interesting thing is that they both use the same connector for the jump starting functions and the output voltage is very close to 12 VDC.  So right away I want to make an adapter cable to a Power Pole with the 45 Amp terminals using 10 AWG super flex wire.

GB150 Jump Starter

2024 The No.co GB150 is an excellent jump starter battery.  Note this does not make a good power bank since it capacity in only 88 Watt hours (88 Wh / 12V = 7.3 Ah)

Power Bank

This is the term for a reasonably small box that has a number of rechargeable batteries and USB outputs.  Typically used to charge cell phones and/or supply 5VDC to USB devices.

Smart Battery Box

The idea is to add features to a classical battery box that might hold a 100 Amp Hour battery.  Things like USB, cigarette lighter, Power Pole sockets.  Metering for charge and/or discharge. 

Licitti - 1000W AC Battery Box PRO is the first one I herd about. ($218 + $55 shipping = $273 (same shipping of more ordered)
Has:On/Off switch, LCD screen, USB & DC ports, built-in Pure Sine Wave 1000W inverter, 10A solar MPPT charge controller, 10 (solar input), 50 (in/Out) & 175 (In/Out) Amp Anderson connectors, holds a group 27/31 size battery.
To make your own power station.

The $799 Ecoflow Delta 2, 10:13 - 1kWh storage (83Ah 12V battery), 1.8kW AC output
The EcoFlow Delta 2 is LOUD! (when AC charging, but it's adjustable)

Power Station

This is a Power Bank that also has a DC to 120 VAC inverter.  These typically have a display similar to those used on UPS power supplies that show the input and output powers.  Some have a provision to directly connect a solar panel (include a MPPT charge controller), in which case they are called "Solar Generators".

USB-C Power Delivery (Wiki)

This is a new technology that allows higher voltages (5, 9, 15, 20, 28, 36 &48) on USB-C ports rated for Power Delivery.  This corresponds to the world wide adoption of USB-C as the default power connector for hand held devices.  So, going forward look for USB-C PD ports both for charging and output.

Description

Annke CP-02A

Not sure what batteries it uses.  There are similar products on eBay that have no case and no batteries, but are intended to use 6 each 18650 batteries.  This would be a 4S2P connection yielding 12V nominal.

I have on order (30 June 2016) one of the "Mobile Power Bank USB DC 6x18650 Battery Charger Car Jump Starter 3.6/5/6/9/12" and some 18650 unprotected batteries for it.  The ad says "Car Jump Starter" but the photos do not show any EC5 connectors.

Load Testing

Using the EL1132 Electronic Load and a custom made EC5-45 Amp Power Pole cable with 10 AWG Super Flex wire.  First built a 10 AWG to Power Pole cable for the EL1132.
See Fig 7 for the test setup.

Battery Capacity Test Table  4 Amp Load

Note the 8 Amp Hour rating this unit is advertised with did not specify the test conditions.  I randomly choose 4 amps for this test.
It turns out that at 4 Amps the capacity is only 1.8 AH.  A back of the envelope calculation:
at half the load current the capacity might double to 4 AH, so at 1 amp load maybe 8 AH capacity.
It makes sense the AH rating would be for the lowest current application, i.e. slow charging a cell phone ( maybe 1/2 amp).
The AH rating when jump starting might be 180 Amps & 10 seconds or 1/2 Amp Hour.

12:14 pm back on charge. Charge LEDs still blinking at 6:30pm

Operation

The USB-A output is normally off and the button needs to be pressed to turn it on.  A quick press turns on the "power on" LEDs.  If there is no load the unit turns itself off after maybe 15 seconds.  This makes it unsuitable for use with low current loads like the GoPro video camera or the WSPRlite radio beacon, both of which have very low standby current drain.

Pressing and holding the button turns on the Flashlight function.  Then a quick press causes fast flashing.  Another quick press results in an SOS Morse code flash.  Another quick press turns the unit off.

The jump start contact seem to be hot all the time.  (That makes sense since switching hundreds of amps is not something that can be done in a small space.

Fraudulent Power Bank

This was advertised on eBay as a power bank & Jump Starter, but when it arrived there were no high current terminals so there's no way it can be used as a high current source.
Marked on front AILI and on back as "Power Banker".  It came without any batteries and needs up to 6 each 18650 Li-Ion cells.

ANKEWR PowerCore20100

This is the newest and best power bank I've got.  It works well with low current loads, like the GoPro video camera or the WSPRlite radio beacon, both of which have very low standby current drain.
The label says:

PowerCore20100
Model: A1271
Capacity: 20100 mAh / 72.36 Wh
Input: 5VDC @ 2A  Output: 5VDC @ 4.8A
Anker Technologies Co. Ltd. | Made in China

Two each USB-A outputs.
Single USBmicro input.

I haven't bought one, but they offer a 400Wh power bank called the "Power House" which includes 5V, 12V and 115VAC outputs, and uses a "12 Volt" input (they say 16 - 17 VDC @ 6A).
The Suaoki unit seems to have more features and a much lower price. PS5B  444Wh, 3 charging methods: AC line, 12/24VDC vehicle or solar panel (
100 Watt panel: 18 VDC @ 5Amp at Equator)
