EBOSSOM Car Battery Jump Starter with Air Compressor JC8 Review

This jump starter has a built-in air compressor, so one unit covers a dead battery and a flat tire. The listing sells it in two battery options, labeled 8000 mha and 12000 mha, at $69.99 and $74.99, and it never states a capacity beyond those two labels. The listing says it is suitable for gasoline engines with a displacement of up to 6.0 liters and diesel engines up to 3.5 liters, and that it connects to 12V vehicles. The compressor side has an LCD, three pressure units and five inflation modes, with a custom mode the listing says reaches 150 PSI.

Specifications

Options and pricing

There are two options, labeled by battery size in the catalog: 8000 mha at $69.99 and 12000 mha at $74.99. The labels spell the unit mha, which is the store's own spelling, and the description gives no capacity of its own. The listing also shows higher struck-through prices of $84.99 and $89.99 for the two options, the store's own figures. The what-you-get list names the jump starter, jumper cables, a pump hose, 4 nozzles, a USB-C charging cable, a manual and an EVA carrying case, and ends with lifetime tech support, a promise whose terms we could not find.

How it compares

Next to the Luxe X8 tire inflator at $74.99, which lists a 2500mAh battery, and the I7 Pro air pump at $39.99, which lists a 6000mAh battery, this is the only one of the three whose listing offers jump starting. The cordless pressure washer from $89.99 is a different kind of tool for cleaning, not for the roadside.

Shipping and processing

• Where it ships. The store's shipping policy says "We currently only support shipping within the United States." It lists places it does not ship to: Alaska, American Samoa, Guam, Hawaii, the Marshall Islands, the Northern Mariana Islands, "Palu" (as written), Puerto Rico, Rhode Island, the U.S. Virgin Islands and the Armed Forces addresses, and it cannot deliver to PO boxes, military or protected areas. It does not mention Canada, the United Kingdom, Australia or New Zealand (checked 2026-11-11).
• Cost and time. The same page says "Free shipping for all the products*" (the asterisk has no note on the page), gives 1-2 business days of processing and 2-7 business days of standard shipping, and says the store offers no choice of courier. It adds that extreme weather can delay delivery.
• Country selector. The footer of the store lets a visitor pick the United States (USD) and eight European countries (Czechia, France, Germany, Italy, the Netherlands, Poland, Portugal, Spain). The shipping policy does not mention them, so we could not tell which is current for orders outside the United States.

Returns and warranty

• Returns. The refund policy gives 30 days after receiving the item to request a return. The item must be in the condition received, unworn or unused, with tags and in its original packaging, with the receipt or proof of purchase. Contact [email protected] first: items sent back without a return request are not accepted. The shipping policy page repeats the 30 days and the same conditions (checked 2026-11-11).
• Costs and refunds. The two pages differ on two points. The refund policy says that if a return is accepted the store sends a return shipping label; the shipping policy says the buyer pays the shipping fee when the return is the buyer's own choice and the store pays when it sent a damaged or wrong item (and charges no restocking fee). The refund policy says an approved refund arrives within 10 business days; the shipping policy says 1-8 business days.
• Not returnable. The refund policy says it cannot accept returns on sale items or gift cards, nor on perishable goods, custom or personalized products, personal care goods, or "hazardous materials, flammable liquids, or gases". Neither page says whether a battery-powered product counts as hazardous, so ask before you buy. For a damaged, defective or wrong item the store asks to be contacted at once. For exchanges it says to return the item and, once the return is accepted, buy the new one separately.
• This listing. The page shows a price of $69.99 against a higher listed price of $84.99. The store's homepage product cards call the lower price "Sale price" and the higher one "Regular price". The refund policy does not accept returns on sale items, while the shipping policy page gives 30 days without that exception, so ask the store before you order.

• Warranty. We found no warranty page on the store. Its terms of service say it does not warrant that products will meet expectations, and that products are provided "as is" and "as available" "except as expressly stated by us", without warranties or conditions of any kind, express or implied (checked 2026-11-11).
• Sign-up perk. The homepage's email sign-up lists an "Auto warranty extension" among its member perks; no page we read gives its terms.
• This product page states no warranty that we could read, so the 'as is' wording above is all we found.

Before you buy

Ships to the United States only. The store's shipping policy supports delivery within the United States and nothing else. If you live in Canada, the United Kingdom, Australia or New Zealand, your country is not listed as a place it ships to (checked 2026-11-11).

EBOSSOM describes itself on its About page as a maker of battery solutions for home, outdoor and daily use, "founded by an elite team responsible for developing power systems for top automotive brands": that is the store's own wording and we could not check it. Its contact page names WENERGY TECHNOLOGIES INC. at a street address in Texas (the city is written "Singapore TX") and gives [email protected] for questions.

We have not read any independent review of this product or of the store, and the store's pages are the only source for its terms.
