20000mAh Car Battery Jump Starter Pack, Baceyong Battery Booster with LED Flashlight USB Ports Clamps, Battery Power Bank Charger for Motorcycles Boat RV

OK, had a few days now.... arrived via P.O. mid strike earlier than expected - tracked, unsigned.(put the willies up me whilst away the weekend before thinking delivered, but no...P.O. should really give option to delay delivery before first attempt...AHEM!)Item:- Picture on box black n yellow - relax item red n black like photo- Hammer front probably only useful on glass (I'd not use as hammer).+ (plus)- Comes charged- USB fastest phone charger I've ever seen (blew my hard charge points away by miles x 3)- Has 4 USB charge points- Rapid unit recharge via plug to mains.- (minus)- universal connects (why I opted for this particular model of starter) not worked for me.... whether due to needing to be connected to smart items (not regular items needing charge) & no polarity control I have no idea. Tried a few. Very disappointing. Guess needs midway transformer of better integrals (board/software). Not tested car cigarette lighter socket but think that has transformer built in.- Compass - as useful as a Chocolate Fireguard in a Foundry! points ok til you move it, then north is south no matter how you jiggle or long you leave it. Enough said.-- Neither Nor :First time I needed to restart 2.0 lt car I did it 4 times (garage in/out + later repeat) Unlike old DRAPER Unit which would like a car battery drag the starter a moment this tiny box just made the car as vigorous as a 17 year old athlete.... no beat missed.... go all day!! GREAT!!Literally as I bring unit back for top up from paltry 98% I am drafting review in mind when I see the charge % suddenly drop..... RAPIDLY!!! 87% 77% now I think what have I done? This is a second a percent or two decreasing! Put charger in it stops. Pull out it drops again fast!Then I remember, first time I used USB to charge phone the unit dropped 2% quick (been in storage awhile I guess) yet when unit charged it rapidly went up 100%Long story short - got down to 26% for 4 starts BUT after a min charge was up to 48%.I guess this may be typical of many lithium units (high discharge low capacity like bike mc batteries).SO trust the display initially less.Conclusion:I would estimate you will get around 7-10 starts with this unit which rapidly recharges REALLY.USB charging I know nothing more rapid.Universal charger.... let me know if it ever works??Car charger - quite probably.Compass - may as well tape over.Hammer - guess glass only emergencyOHHH! The LIghts - yep a long press on/off for torch which is two bright LED, other presses produce sos pattern etc (WTH sales point) if you press power rapidly twice you get flashing red n blue led lights (WHY!!! put on your dashboard n think you're batman???)Nutshell - cracking starter, USB charger (hope does not blow my MC bike relay....why I bought, think will not, unlike starting connected to my running car ..untested as of now) .... not a bad buy.
